Barca</a> (University of Melbourne).</p> <p>Molecular dynamics is a computer simulation method that has been developed to better understand the movements of atoms and molecules within a system. Among the different approaches taken are <em>Ab Intio</em> (or first principles) calculations, whereby scientists use what is known of the fundamental laws of nature to develop the algorithms they run on computers.</p> <p>Accurate simulations of the properties of molecules and atoms (as well as how they interact) can lead to a wide range of societal benefits, including developing therapeutic drugs, producing biofuels, recycling plastics, and engineering medical biomaterials.</p> <p>Although the use of computers for performing molecular dynamics simulations goes back several decades, many traditional approaches have been limited by the accuracy of the force fields (computational models computer scientists develop to describe the forces between atoms and molecules). These limits have undermined the accuracy of the resulting simulations.</p> <p>While other approaches such as quantum mechanical methods have delivered the desired accuracy, they were not able to scale on powerful supercomputers to model the thousands of atoms within a biosystem.</p> <p>To address this challenge, the Gordon Bell Prize-winning team developed a new technique combining methods called <em>molecular fragmentation</em> and <em>MP2 perturbation theory</em>.</p> <p>Using their algorithmic innovations on a powerful exascale computer, the team was able to achieve a record-breaking performance of simulating more than one million electrons for a computational chemistry application, and to scale their algorithm to an EFlop/s (processing a quintillion calculations per second). The Gordon Bell Prize-winning team’s resulting simulation is 1,000 times larger in system-size than the existing state-of-the-art, and was processed 1,000 times faster than any previous model.</p> <p>The Gordon Bell Prize-winning team performed several Ab Initio Molecular Dynamics (AIMD) time steps on a molecular cluster with over two million electrons utilizing 9,400 nodes on the Frontier exascale supercomputer, significantly larger than any previous AIMD or static energy and/or gradient calculation at a comparable level of accuracy. These calculations achieve 1006.7 PFLOP/s providing a throughput efficiency of 59% of attainable FP64 peak on 99.9% of the machine. In addition, the team demonstrated low time step latency of 3.4 s/timestep on a protein fragment with 1,496 atoms and over 5,500 electrons attaining a simulation throughput of 25,000 time steps per day on 1,024 nodes of Perlmutter.</p> <p>In their paper, the 2024 ACM Gordon Bell Prize-winning team claims, “This leap forward is not merely incremental; it redefines the boundaries of what is computationally feasible in molecular dynamics, setting a new benchmark for accuracy and efficiency in large-scale simulations. The enhanced scalability and accuracy of our simulation techniques empowers the scientific community to tackle longstanding challenges in both chemistry and biology.”</p> <p>The Frontier supercomputer, located at the Oak Ridge National Laboratory in Oak Ridge, Tennessee, is the world’s first and fastest exascale supercomputer. It can perform a quintillion (a billion billion) operations per second. When Frontier came online in 2022, it was 2.5 times faster than the world’s second most powerful supercomputer. As of November 2024, Frontier <a href="https://top500.org/lists/top500/list/2024/11/"> is ranked as the world’s second most powerful supercomputer</a>. The Perlmutter supercomputer is housed at the (US) National Energy Research Scientific Computing Center (NERSC). It is used primarily in applications including climate analysis, quantum information science, clean energy technologies, as well as semiconductors and microelectronics. As of November 2024, it is ranked as the world’s 19<sup>th</sup> most powerful supercomputer.</p></div> </div> <div class="awards-winners__related-content"> <h3> 2023 ACM Gordon Bell Prize Awarded to International Team for Materials Simulations Which Achieve Quantum Accuracy at Scale</h3> <div class="awards-winners__related-content-body"> <p>ACM, the Association for Computing Machinery, named an eight-member team drawn from American and Indian institutions as the winner of the 2023 ACM Gordon Bell Prizefor the project, “<a href="https://dl.acm.org/doi/10.1145/3581784.3627037">Large-Scale Materials Modeling at Quantum Accuracy: <em>Ab Initio</em> Simulations of Quasicrystals and Interacting Extended Defects in Metallic Alloys</a>.”</p> <p>The members of the team are: <a href="https://awards.acm.org/award-recipients/das_3170153">Sambit Das</a> (University of Michigan), <a href="https://awards.acm.org/award-recipients/kanungo_5691160">Bikash Kanungo</a> (University of Michigan), <a href="https://awards.acm.org/award-recipients/subramanian_3878405">Vishal Subramanian</a>, (University of Michigan), <a href="https://awards.acm.org/award-recipients/panigrahi_3236308">Gourab Panigrahi</a> (Indian Institute of Science, Bangalore), <a href="https://awards.acm.org/award-recipients/motamarri_4291569">Phani Motamarri</a> (Indian Institute of Science, Bangalore), <a href="https://awards.acm.org/award-recipients/rogers_8914944">David Rogers</a> (Oakridge National Laboratory), <a href="https://awards.acm.org/award-recipients/zimmerman_2420676">Paul M.

In their abstract to their Gordon Bell Prize-winning project the authors write, “ <em> Ab initio </em> electronic-structure has remained dichotomous between achievable accuracy and length-scale. Quantum Many-Body (QMB) methods realize quantum accuracy but fail to scale.”</p> <p>To address this challenge, the Gordon Bell Prize-winning team developed a framework that combines the accuracy provided by QMB methods with the efficiency of Density-Functional Theory (DFT) to access larger length scales at quantum accuracy—a goal that existing approaches have not been able to achieve.</p> <p>The 2023 ACM Gordon Bell Prize-winning team writes, “We demonstrate a paradigm shift in DFT that not only provides an accuracy commensurate with QMB methods in ground-state energies, but also attains an unprecedented performance of 659.7 PFLOPS (43.1% peak FP64 performance) on 619,124 electrons using 8,000 GPU nodes of Frontier supercomputer.”</p> <p>The <a href="https://awards.acm.org/bell/">ACM Gordon Bell Prize</a> tracks the progress of parallel computing and rewards innovation in applying high-performance computing to challenges in science, engineering, and large-scale data analytics.

Teams at Google and the University of Science and Technology of China in Hefei both claim to have developed devices that have achieved quantum supremacy.</p> <p>According to the Gordon Bell Prize recipients, determining whether a device has achieved quantum supremacy for a given task (in a specific scenario) begins with sampling the interactions of the different quantum bits (qubits) in a random quantum circuit (RQC). As the number of possible interactions among qubits in a random quantum circuit is staggeringly large, simulating their interactions is a problem well-suited for a high-performance computer. However, the quantum physics behind the entangled qubits requires that the classical binary bits used in a supercomputer store and compute the information with exponentially-increasing complexity.</p> <p>In their Gordon Bell Prize-winning work, the Chinese researchers introduced a systematic design process that covers the algorithm, parallelization, and architecture required for the simulation. Using a new Sunway Supercomputer, the Chinese team effectively simulated a 10x10x (1+40+1) random quantum circuit (a new milestone for classical simulation of RQC). Their simulation achieved a performance of 1.2 Eflops (one quintillion floating-point operations per second) single-precision, or 4.4 Eflops mixed-precision, using over 41.9 million Sunway cores (processors).</p> <p>The project far outpaced state-of-the-art approaches to simulating an RQC. For example, the most recent effort, using the Summit supercomputer to simulate a random quantum circuit of the Google Sycamore quantum processor (which has 53 qubits), was estimated to take 10,000 years to perform. By contrast, the Chinese team’s approach employing the Sunway supercomputer takes only 304 seconds for a simulation of similar quantum complexity.</p> <p>The Chinese team explained that they undertook this challenge because achieving real-time simulation of an RQC using a supercomputer would aid both in the development of quantum devices and in bringing algorithmic and architectural innovations within the traditional supercomputing community.</p> <p>The <a href="https://awards.acm.org/bell/" target="_blank">ACM Gordon Bell Prize</a> tracks the progress of parallel computing and rewards innovation in applying high performance computing to challenges in science, engineering, and large-scale data analytics.

MD simulations allow scientists to gain a better sense of how a system (which could include anything from a single cell to a cloud of gas) progresses over time. Practical applications of molecular dynamics include studying large molecules such as proteins for drug development.</p> <p><em>Ab initio</em> (meaning in Latin “from the beginning” or “from first principles”) Molecular Dynamics (AIMD) is an approach that differs slightly from Standard Molecular Dynamics (SMD) in how interatomic forces are calculated during the simulation. The level of precision that can be gained through AIMD has made it the preferred simulation method of scientists for more than 35 years. At the same time, while AIMD allows for greater accuracy, the approach requires more computation—and has therefore been limited to the study of small-sized systems (systems that have a maximum size of thousands of atoms).</p> <p>In their Gordon Bell Prize-winning paper, the team introduced Deep Potential Molecular Dynamics (DPMD). DPMD is a new machine learning-based protocol that can simulate a more than 1 nanosecond-long trajectory of over 100 million atoms per day. While other machine learning-based protocols have been introduced for MD simulations in recent years, the authors contend that their protocol achieves the first efficient MD simulation of 100 million atoms with <em>ab initio</em> accuracy.</p> <p>As the Gordon Bell Prize recognizes achievement in high performance computing, finalists must demonstrate that their proposed algorithm can scale (run efficiently) on the world’s most powerful supercomputers. The team developed a highly optimized code (GPU Deep MD-Kit), which they successfully ran on the Summit supercomputer. The team’s GPU Deep MD-Kit efficiently scaled up to the entire Summit supercomputer, attaining 91 PFLOPS (1 PFLOP = 1 quadrillion floating operation points per second) in double precision (45.5% of the peak) and 162/275 PFLOPS in mixed-single/half precision.</p> <p>The Summit supercomputer, developed by IBM for the (US) Oak Ridge National Laboratory, was the first supercomputer to reach exaflop speed (1 quintillion operations per second), and was the world’s fastest supercomputer from November 2018 to June 2020.</p> <p>In the abstract of their paper, the Gordon Bell Prize winning team wrote, “The great accomplishment of this work is that it opens the door to simulating unprecedented size and time scales with <em>ab initio</em> accuracy. It also poses new challenges to the next-generation supercomputer for a better integration of machine learning and physical modeling.”</p> <p>The award was presented by ACM President Gabriele Kotsis and Bronis de Supinski, Chair of the 2020 Gordon Bell Prize Award Committee, during the <a href="https://sc20.supercomputing.org" target="_blank"> International Conference for High Performance Computing, Networking, Storage and Analysis (SC20)</a>, which was held virtually for the first time.</p></div> </div> <div class="awards-winners__related-content"> <h3> 2019 ACM Gordon Bell Prize Awarded to ETH Zurich Team for Developing Simulation that Maps Heat in Transistors</h3> <div class="awards-winners__related-content-body"> <p>ACM named a six-member team from the Swiss Federal Institute of Technology (ETH) Zurich recipients of the 2019 ACM Gordon Bell Prize for their project, “A Data-Centric Approach to Extreme-Scale Ab initio Dissipative Quantum Transport Simulations.”</p> <p>The ETH Zurich team introduced DaCe OMEN, a new framework for simulating the transport of electrical signals through nanoscale materials (such as the silicon atoms used in transistors). To better understand the thermal properties of transistors, the team simulated how electricity would be transported through a two-dimensional slice of transistor consisting of 10,0000 atoms. The ETH Zurich researchers simulated the 10,000-atom system 14 times faster than an earlier framework that was used for a 1,000-atom system. The DaCe OMEN code they developed for the simulation has been run on two top-6 hybrid supercomputers, reaching a sustained performance of 85.45 Pflop/s on 4,560 nodes of Summit (42.55% of the peak) in double precision, and 90.89 Pflop/s in mixed precision.</p> <p>The <a href="https://awards.acm.org/bell">ACM Gordon Bell Prize</a> tracks the progress of parallel computing and rewards innovation in applying high performance computing to challenges in science, engineering, and large-scale data analytics.

Pancake and Arndt Bode, Chair of the 2019 Gordon Bell Prize Award Committee, during the <a href="https://sc19.supercomputing.org" target="_blank">International Conference for High Performance Computing, Networking, Storage and Analysis (SC19)</a> in Denver, Colorado.</p> <p>Today’s commercial microchips contain 100,000,000 transistors in the span of a single millimeter, and managing heat generation and dissipation is one of the central problems in computer architecture. As the transistors on each microchip have become smaller and more densely packed, the amount of heat they generate has steadily increased. The cooling systems needed to keep supercomputers and data centers from overheating have become increasingly expensive. They estimate that cooling can consume up to 40% of the total electricity needed for data centers, amounting to cumulative costs of many billions of dollars per year.</p> <p>Today’s supercomputers, which can perform up to 200 quadrillion calculations per second, allow scientists in many disciplines to gain new insights by processing a staggering number of variables. The ETH Zurich team used their simulation to develop a map of where heat is produced in a single transistor, how it is generated and how it is evacuated. It is hoped that a deeper understanding of these thermal characteristics could inform the development of new semiconductors with optimal heat-evacuating properties.</p> <p>In recent years, the OMEN framework has been a popular quantum transport simulator for modeling nanoscale materials, but has experienced scaling bottlenecks. The ETH Zurich Team wrote a variation of OMEN that is Data Centric (DaCe OMEN). “We show that the key to eliminating the scaling bottleneck is in formulating a communication-avoiding algorithm,” the team writes in their paper. The ETH Zurich team’s solver yields data movement characteristics that can be used for performance and communication modeling, communication avoidance, and dataflow transformations. They go on to note that the speedup made by the DaCe OMEN framework is two orders of magnitude faster per atom than the original OMEN code.</p> <p>The ETH Zurich team also built a graphical interface for the DaCe OMEN framework that includes a visualization of dataflow in lieu of a simple textual description. Anyone running the code can use the image representation to interact with the data directly. The team believes this new innovation could be applied to numerous scientific disciplines beyond nanoelectronics.</p> <p>Winning team members include <a href="/award_winners/ziogas_5092899">Alexandros Nikolaos Ziogas</a>, <a href="/award_winners/ben-nun_8472723">Tal Ben-Nun</a>, <a href="/award_winners/schneider_5912517">Timo Schneider</a> and <a href="/award_winners/hoefler_4381890">Torsten Hoefler</a>, from ETH Zurich’s Scalable Parallel Computing Laboratory, as well as <a href="/award_winners/fernandez_0087167">Guillermo Indalecio Fernández</a> and <a href="/award_winners/luisier_6647158">Mathieu Luisier</a> from ETH Zurich’s Integrated Systems Laboratory.</p></div> </div> <div class="awards-winners__related-content"> <h3> Two Teams Honored with 2018 ACM Gordon Bell Prize for Work in Combating Opioid Addiction, Understanding Climate Change</h3> <div class="awards-winners__related-content-body"> <p>ACM named two teams to receive the 2018 ACM Gordon Bell Prize.

Prior to the awards ceremony, all of the Gordon Bell Prize finalists presented their papers during SC18.</p> <p><em><strong>Employing Supercomputers to Combat the Opioid Epidemic</strong></em><br /> <b>Paper Title:</b> “Attacking the Opioid Epidemic: Determining the Epistatic and Pleiotropic Genetic Architectures for Chronic Pain and Opioid Addiction"<br /> <strong>Prize Category:</strong> Sustained Performance Prize<br /> <strong>Team:</strong> Oak Ridge National Laboratory<br /> According to the US Centers for Disease Control and Prevention (CDC), 115 people die every day in the US from opioid overdoes. Additionally, the CDC found that there was a 30% increase in opioid overdoes in the period between July 2016 and September 2017 in 52 areas and 45 states. The aim of the Oak Ridge National Laboratory (ORNL) team is to use supercomputing to provide a tool in combating the opioid epidemic by understanding the underlying genetic architecture of how individuals develop chronic pain and respond to opioids. ORNL team members also believe that their project will help with the identification of new therapeutic approaches for opioid misuse. Genome-wide association studies (GWASs) have led to important discoveries in varied types of diseases. For a genome dataset, the ORNL team had access to the Million Veterans Program (MVP), a joint initiative of the US Department of Energy and the US Veterans Administration (VA). The MVP dataset includes 750,000 human genome types, associated with more than a billion medical records over a 20-year period.</p> <p>The ORNL team developed a new “CoMet” algorithm that allows supercomputers to process vast amounts of genetic data and identify genes that may be more susceptible to pain and opioid addiction—as well as promising treatments. By running the ORNL team’s algorithm, supercomputers were able to successfully process genetic data at a magnitude that is four to five times greater than the latest state-of-the-art approaches.

Increasingly, state and local governments are interested in the question of how extreme weather events will change (or affect) their local communities. In order to address these important questions, climate scientists routinely configure and run high-fidelity simulations under a range of different climate change scenarios. Recently, it has been shown that deep learning methods, wherein artificial neural networks vaguely inspired by the human brain learn from large amounts of data, can be applied to better understand extreme weather conditions. Using high-performance computers, the Lawrence Berkeley National Laboratory (LBNL) team trained a deep neural network to identify extreme weather patterns from high-resolution climate simulations. They demonstrated that accurate datasets can be computed for weather patterns such as tropical cyclones and atmospheric rivers.</p> <p>To train the neural network, the LBNL team paper proposed an innovative blend of hardware and software solutions. These included a novel architecture as well as a number of system-level innovations to enable the largest graphics processing units (GPU)-based HPC systems in the world to process vast amounts of weather-related data.

For example, the Chinese team’s 3D simulations may inform engineering standards for buildings being developed in zones known to have seismic activity. In this vein, many have advocated for a significant increase in the amount of sensors to regularly monitor seismic activity. The Tangshan earthquake, which occurred on July 28, 1976 in Tangshan, Hebei, China, is regarded as the most devastating earthquake of the 20<sup>th</sup> century, and resulted in approximately 242,000-700,000 deaths. In developing their simulations for the Tangshan earthquake, the winning team included input data from the entire spatial area of the quake, a surface diameter of 320 km by 312 km, as well as 40 km deep below the earth’s surface. The input data also included a frequency range of the earthquake of up to 18 Hz (Hertz). In the study of earthquakes, a Hertz is a unit of measurement that measures the number of times an event happens in the period of a second. For example, it might correspond to the number of times the ground shakes back and forth during an earthquake. Previous simulations of violent earthquakes have employed a lower frequency than 18 Hz, since enormous memory and time consumption are needed for high frequency simulations.</p> <p>This year’s winning team is not the first to develop algorithms for supercomputers in an effort to simulate earthquake activity. In the abstract of their presentation, the 2017 Gordon Bell recipients write: “Our innovations include: (1) a customized parallelization scheme that employs the 10 million cores efficiently at both the process and thread levels; (2) an elaborate memory scheme that integrates on-chip halo exchange through register communication, optimized blocking configuration guided by an analytic model, and coalesced DMA access with array fusion; (3) on-the-fly compression that doubles the maximum problem size and further improves the performance by 24%."</p> <p>Of its new innovations, the Chinese team adds that its on-the-fly compression scheme may be effectively applied to other challenges in exascale computing. In their paper, the authors state: “The even more exciting innovation is the on-the-fly compression scheme, which, at the cost of an acceptable level of accuracy lost, scales our simulation performance and capabilities even beyond the machine’s physical constraints. While the current compression scheme is largely customized for our specific application and the Sunway architecture, we believe the idea has great potential to be applied to other applications and other architectures.”</p> <p>Winning team members include <a href="/award_winners/fu_0834628">Haohuan Fu</a>, Tsinghua University and National Supercomputing Center, Wuxi, China; <a href="/award_winners/he_2344210">Conghui He</a>, Tsinghua University and National Supercomputing Center, Wuxi, China; <a href="/award_winners/chen_0613492">Bingwei Chen</a>, Tsinghua University and National Supercomputing Center, Wuxi, China; <a href="/award_winners/yin_5835769">Zekun Yin</a>, Shandong University; <a href="/award_winners/zhang_8268883">Zhenguo Zhang</a>, Southern University of Science and Technology, China; <a href="/award_winners/zhang_8680907">Wenqiang Zhang</a>, University of Science and Technology of China; <a href="/award_winners/zhang_9366313">Tingjian Zhang</a>, Shandong University; <a href="/award_winners/xue_7407473">Wei Xue</a>, Tsinghua University and National Supercomputing Center, Wuxi, China; <a href="/award_winners/liu_7402178">Weiguo Liu</a>, Shandong University; <a href="/award_winners/yin_6066691">Wanwang Yin</a>, National Research Center of Parallel Computer Engineering and Technology, China; <a href="/award_winners/yang_2304814">Guangwen Yang</a>, Tsinghua University and National Supercomputing Center, Wuxi, China; and <a href="/award_winners/chen_6182978">Xioafei Chen</a>, Southern University of Science and Technology, China.</p> <p>Innovations from advanced scientific computing have a far-reaching impact in many areas of science and society—from understanding the evolution of the universe and other challenges in astronomy, to complex geological phenomena, to nuclear energy research, to economic forecasting, to developing new pharmaceuticals.

The <a href="https://awards.acm.org/bell">ACM Gordon Bell Prize</a> tracks the progress of parallel computing and rewards innovation in applying high performance computing to challenges in science, engineering, and large- scale data analytics. The award was bestowed during the <a href="http://sc16.supercomputing.org/" target="_blank">International Conference for High Performance Computing, Networking, Storage and Analysis (SC16) </a>in Salt Lake City, Utah.</p> <p>Since the dawn of computing, scientists have used data analytics in an effort to predict and simulate the weather and related atmospheric events. In the early years of weather forecasting, scientists might have used standard central processing units (CPUs). With each passing year, the continued expansion in the capabilities of high performance computers has enabled researchers to employ increasingly sophisticated computational methods for the analysis and modeling of weather patterns. Advanced scientific computers break problems down into composite parts and perform immense amounts of mathematical calculations simultaneously. The performance of a supercomputer is measured in floating-point operations per second (FLOPS). Some of the latest supercomputers are capable of performing quadrillions of FLOPS.</p> <p>In the abstract of their presentation, the winning team writes, “On the road to the seamless weather-climate prediction, a major obstacle is the difficulty of dealing with various spatial and temporal scales. The atmosphere contains time-dependent multi-scale dynamics that support a variety of wave motions.”</p> <p>To simulate the vast number of variables inherent in a weather system developing in the atmosphere, the winning group presents a highly scalable fully implicit solver for three-dimensional nonhydrostatic atmospheric simulations governed by fully compressible Euler equations. Euler equations are a set of equations frequently used to understand fluid dynamics (liquids and gasses in motion).</p> <p>Elaborating further, they add, “In the solver, we propose a highly efficient domain-decomposed multigrid preconditioner that can greatly accelerate the convergence rate at the extreme scale. For solving the overlapped subdomain problems, a geometry-based pipelined incomplete LU factorization method is designed to further exploit the on-chip fine-grained concurrency.”</p> <p>The fully-implicit solver successfully scales to the entire system of the Sunway TaihuLight, a Chinese supercomputer with over 10.5 M heterogeneous cores, allowing for a performance of 7.95 PFLOPS in double precision.

The research was conducted by scientists at ETH Zurich and IBM Research, in collaboration with the Technical University of Munich and the Lawrence Livermore National Laboratory (LLNL). The results were presented by the team at SC13 sc13.supercomputing.org in Denver, where the recipient of the ACM Gordon Bell Prize was announced on November 21. The simulation conducted by the team resolved unique phenomena associated with clouds of collapsing bubbles. This condition occurs when vapor bubbles formed in a liquid collapse due to changes in pressure. The successful effort employed 13 trillion cells and 6.4 million threads on LLNL’s “Sequoia” IBM BlueGene/Q, one of the fastest supercomputers in the world. The simulation resolved 15,000 bubbles and a 20-fold reduction in time to solution over previous research. The paper describing this achievement was one of six papers chosen as finalists for the 2013 Gordon Bell Prize awarded by ACM acm.org.</p> <p>Members of the team included <a href="https://awards.acm.org/award_winners/rossinelli_5822684">Diego Rossinelli</a>, <a href="https://awards.acm.org/award_winners/hejazialhosseini_7150645">Babak Hejazialhosseini</a>, <a href="https://awards.acm.org/award_winners/hadjidoukas_2021223">Panagiotis Hadjidoukas</a>, and <a href="https://awards.acm.org/award_winners/koumoutsakos_9630986">Petros Koumoutsakos</a> from ETH Zurich; <a href="https://awards.acm.org/award_winners/bekas_2827862">Costas Bekas</a> and <a href="https://awards.acm.org/award_winners/curioni_5574962">Alessandro Curioni</a> from IBM Zurich Research Laboratory; <a href="https://awards.acm.org/award_winners/bertsch_1965627">Adam Bertsch</a> and <a href="https://awards.acm.org/award_winners/futral_6922599">Scott Futral</a> from Lawrence Livermore National Laboratory; and <a href="https://awards.acm.org/award_winners/schmidt_2458388">Steffen Schmidt</a> and <a href="https://awards.acm.org/award_winners/adams_5274107">Nikolaus Adams</a> from Technical University Munich.</p> <p><a href="/binaries/content/assets/press_releases/bell-2013.pdf">Press Release</a></p></div> </div> </div> </div> </div> <div class="columns large-4 medium-4 small-12 zone-3"> <div> <div> <div class="articles single-cta"> <div class="two-col-alt article-block"> <div class="row" data-equalizer=""> <div class="large-12 medium-12 small-12 columns"> <div class="cta shadowed " data-equalizer-watch=""> <div class="row" style="margin: inherit;"> <div class="medium-12 columns d-table top-cta"> <div class="text-wrap"> <h2 class="text-left"></h2> <div class="dek"> <div> <div class="panel awards-navigation"> <h2 class="sidebar-header"><a href="/list-of-awards">Full List of ACM Awards</a></h2> </div> </div></div> </div> </div> </div> </div></div> </div> </div> </div> </div> <div> <div class="panel awards-navigation"> <h2 class="sidebar-header">ACM Awards by Category</h2> <div class="data-list"> <dl class="awards-navigation__accordion accordion" data-accordion> <dd class="accordion-navigation"> <a href="#awards_34_0" class="awards-navigation__link"> <h3>Career-Long Contributions</h3> </a> <div id="awards_34_0" class="awards-navigation__content content"> <a class="awards-navigation__link" href="/turing">ACM A.M.
