The George Michael Memorial Fellowship honors exceptional PhD students throughout the world whose research focus is high-performance computing (HPC) applications, networking, storage, or large-scale data analytics.</p> <p>Fan is recognized for her research in three key areas of high-performance computing: optimizing the performance of MPI collectives, enhancing the performance of irregular parallel I/O operations, and improving the scalability of performance introspection frameworks. Nichols is recognized for advancements in machine-learning based performance modeling and the advancement of large language models for HPC and scientific codes.</p> <p><strong>Ke Fan</strong></p> <p>Fan’s research focuses on improving the performance of data movement associated with collective communication and parallel file I/O operations on large-scale supercomputers. Her most recent focus has been on two main areas: (1) Optimizing inter-process data movement, particularly in the context of all-to-all collectives, where all processes engage in data exchange. In this area, she has developed a new class of parameterized hierarchal algorithms that substantially improve the performance of both uniform and non-uniform all-to-all collectives. (2) Optimizing parallel I/O, targeting applications that generate unbalanced, irregular I/O workloads. Fan has specifically developed spatially aware data aggregation techniques that enhance load balancing and improve overall parallel I/O performance.</p> <p>In addition to these two areas, she has made significant progress in improving the scalability of performance introspection frameworks, which help developers understand data movement capabilities in HPC systems. With these new insights, developers can identify bottlenecks and optimize performance at scale.</p> <p><strong>Daniel Nichols </strong></p> <p>Nichols’ research is broadly centered around the intersection of machine learning (ML) and high-performance computing. His most recent focus has been on two main areas: (1) developing novel ML-based performance models to make use of all available performance data when making predictions about code runtime properties, and (2) adapting state of the art large language model (LLM) techniques to HPC applications. By utilizing recent advances in representation learning and further advancing them to handle the unique challenges of performance modeling, Nichols’ research seeks to develop models that make use of all available data when predicting performance. This research has the potential to significantly improve both the quality and applicability of performance models.</p> <p>By adapting LLM’s to HPC applications, Nichols’ work has improved their performance on HPC development tasks. He has created scientific and parallel code capable LLMs and methods for improving the quality of current models for HPC. This is part of his goal towards creating specialized LLMs to solve software complexities and allow scientists to focus on their domain research and less on the intricacies of HPC development.</p> <p><a href="https://awards.acm.org/hpc-fellows">The ACM-IEEE CS George Michael Memorial HPC Fellowship</a> is endowed in memory of George Michael, one of the founders of the SC Conference series.

He is bringing the Function-as-a-Service (FaaS) programming model into the HPC domain by developing high-performance software and hardware solutions for the serverless stack. By solving the fundamental performance challenges of FaaS, he is building a fast, efficient programming model that brings innovative cloud techniques into HPC data centers, allowing users to benefit from pay-as-you-go billing and helping operators to decrease running costs and their environmental impact.To that end, he has been working on tailored solutions for different levels of the FaaS computing stack, from computing and network devices up to high-level optimizations and efficient system designs. He has also proposed a new design for serverless platforms that applies HPC practices such as low-latency networking, data locality, and efficient communication.</p> <p><strong>Masado Alexander Ishii</strong><br /> Ishii is the main developer for the University of Utah’s Dendro-KT framework for four-dimensional adaptivity and parallel in time formulations. Given the ever-increasing levels of parallelism in the largest machines, parallelizing across space is not sufficient—and in many cases the inability to parallelize in time is the biggest bottleneck for several important problems. The Dendro-KT framework addresses this problem and also enables the development of high-orders and variable order in time formulation (similar to p-refinement). Working with collaborators, Ishii has also been involved in developing methods and codes for large-scale fluid simulations around complex objects, including a case with multiple complex objects, to evaluate COVID-19 transmission risk in classrooms.</p> <p><strong>Shelby Lockhart</strong><br /> Lockhart has made contributions in parallel communication, core parallel numerical algorithms, and advancing capabilities of large-scale predictive simulation. Her focus has been on modeling performance in heterogeneous settings, with an eye on redesigning the message communication “under-the-hood” (aspects of the high-performance architecture that are not readily visible) as well as looking at fundamental algorithmic changes in order to significantly improve achievable performance. Among her research highlights, she has provided detailed communication models to drive the selection of message routing, yielding impressive improvements across a range of problem types. She has also presented a strategy for achieving impressive reductions in communication costs in graphic processing unit (GPU) systems by communication through the host, accounting for different data volumes and GPU counts. Additionally, Lockhart’s thesis work on fixed point solvers has made important contributions to the Suite of Nonlinear and Differential/Algebraic Equation Solvers (SUNDIALS) project.</p> <p>The ACM-IEEE CS George Michael Memorial HPC Fellowship is endowed in memory of George Michael, one of the founders of the SC Conference series.

Hidayetoglu is recognized for contributions in scalable sparse applications using fast algorithms and hierarchical communication on supercomputers with multi-GPU nodes. Patel is recognized for contributions toward making the current error-prone quantum computing systems more usable and helping HPC programmers solve computationally challenging problems.</p> <p><strong>Mert Hidayetoglu</strong><br /> Sparse operations are the main computational workload for numerous scientific, AI and graph analytics applications. Most of the time, the costs of computation and communication for distributed sparse operations constitute an overall performance bottleneck.</p> <p>Hidayetoglu’s research investigates this bottleneck at two specific points: memory accesses and communication. He has proposed and demonstrated two novel techniques: sparse matrix tiling and hierarchical communications. The first technique, sparse matrix tiling, accelerates sparse matrix multiplication on a single GPU by the preprocessing of sparse data access patterns and constructs necessary data structures accordingly. The second technique, hierarchical communications, eliminates the communication bottleneck , which typically dominates end-to-end execution time when large problems at terabyte (TB) scale fit on only hundreds of GPUs. Hidayetoglu’s technique performs sparse communications (depending on the sparsity pattern of the matrix) locally-first to reduce the costly data communication across nodes.</p> <p>Hidayetoglu has successfully demonstrated these techniques in award-winning applications, including large-scale X-ray imaging at Argonne National Laboratory and accelerated sparse deep neural network inference at IBM. Related papers at SC20 and HPEC20 won the best paper award and the Sparse Challenge championship title, respectively.</p> <p><strong>Tirthak Patel</strong><br /> Patel's research addresses the challenge of erroneous program executions on quantum computers and provides robust solutions to improve their reliability. Despite rapid progress in quantum computing, prohibitively high noise on existing near-term intermediate-scale quantum (NISQ) computers remains a fundamental roadblock in the wider adoption of quantum computing. Due to the high noise, program executions on existing quantum computers produce erroneous program outputs. Quantum computing programmers largely lack the tools to estimate the correct output from these noisy program executions.</p> <p>Patel, advised by Devesh Tiwari at Northeastern University, is designing cross-layer system software for extracting meaningful output from erroneous executions on quantum computers. In particular, he first led the effort to benchmark and characterize the performance of different quantum algorithms on IBM quantum computers. Patel leveraged insights gained from this measurement-based experimental effort to inform the design of his novel tools and methods, including VERITAS, QRAFT, UREQA, and DisQ.</p> <p>For example, his technique VERITAS demonstrates how carefully-designed statistical methods can mitigate errors post-program execution and help programmers deduce the correct program output effectively. Patel's other solution, QRAFT, leverages the reversibility property of quantum operations to deduce the correct program output, even when the program is executed on qubits with relatively high error rates. Both approaches relieve programmers and compilers from the burden of selecting the qubits with the least error rate, a significant departure from existing approaches in this area. Patel's work lowers the barrier to entry into quantum computing for HPC programmers by open-sourcing multiple novel datasets and system software frameworks.</p></div> </div> <div class="awards-winners__related-content"> <h3> 2020 ACM-IEEE CS George Michael Memorial HPC Fellowships</h3> <div class="awards-winners__related-content-body"> <p><a href="/award_winners/cheshmi_7648822">Kazem Cheshmi</a> of the University of Toronto, <a href="/award_winners/vardhan_2682145">Madhurima Vardhan</a> Duke University, and <a href="/award_winners/zhou_9901476">Keren Zhou</a> of Rice University are the recipients of the <a href="https://awards.acm.org/hpc-fellows">2020 ACM-IEEE CS George Michael Memorial HPC Fellowships</a>. Cheshmi is recognized for his work building a Sympiler that automatically generates efficient parallel code for sparse scientific applications on supercomputers. Vardhan is recognized for her work developing a memory-light massively parallel computational fluid dynamic algorithm using routine clinical data to enable high-fidelity simulations at ultrahigh resolutions. Zhou is recognized for his work developing performance tools for GPU-accelerated applications. The Fellowships are jointly presented by ACM and the IEEE Computer Society.</p> <p><strong>Kazem Cheshmi</strong><br /> In mathematics, a matrix is a grid (represented in a table of rows and columns) that is used to store, track and manipulate various kinds of data. In computer science, matrices are especially used in graphics, where an image is represented as a matrix in which each datapoint on the matrix table would directly correspond to the color and/or intensity of a given pixel. Matrix computations have a wide range of practical uses. For example, a 3D graphics programmer would hold all the datapoints related to an image as elements of the matrix and might make matrix computations to cause the image to rotate or scale. Matrix computations also play an essential role in computer vision, a branch of AI in which a computer learns to identify an image.</p> <p>Historically, mathematicians would develop algorithms for matrix computations, and software engineers would write programs to make the algorithms run on powerful parallel computers. However, the emergence of massive datasets has meant that traditional approaches to matrix computation are often inadequate for the enormous matrices, requiring complex algorithms that are increasingly used today in areas such as data analytics, machine learning, and high performance computing.</p> <p>To address this problem, Cheshmi has developed Sympiler, a domain-speciﬁc compiler (a program that translates the source code from a programming language to a code the computer can understand). Cheshmi’s Sympiler generates high performance codes for sparse numerical methods and can process complex matrix computations derived from massive datasets. Sympiler is extended to nonlinear optimization algorithms and performs faster than existing nonlinear optimization tools and is scalable to some of the most powerful high performance computers. Cheshmi’s work was also accepted to <a href="https://s2020.siggraph.org" target="_blank">SIGGRAPH 2020</a>, where he demonstrated how he is using Sympiler in robotics and graphics applications.</p> <p><strong>Madhurima Vardhan</strong><br /> Despite recent advances, cardiovascular disease (CVD) remains the leading cause of deaths worldwide. In the field of high performance computing, some researchers develop algorithms that are processed on powerful supercomputers to create visual simulations of complex biological processes. These simulations can be useful tools to help researchers better understand how to treat disease. Currently, a form of simulation called a computational fluid dynamic (CFD) simulation is used in health clinics to provide noninvasive diagnosis of CVDs.</p> <p>However, existing state-of-the-art CFD simulations do not provide high-fidelity real-time diagnosis of CVDs. These limitations stem from a variety of factors, including problems with model accuracy based on the patient images that comprise the datasets; the extensive memory requirements of these kinds of simulations; the long runtimes on high performance computers that are required for these kinds of simulations; and teaching physicians how to effectively use these simulations.</p> <p>To address these problems, Vardhan is developing a new kind CFD algorithm using routine patient image datasets that can develop high-fidelity simulations at ultra-high resolutions. Her algorithm is memory-light (that is, using less memory than existing algorithms), and massively parallel (proven to scale on supercomputers). As part of her PhD work, she also completed a study to determine how physicians interact with simulation data, and how physician behavior might be modified in treatment planning.</p> <p><strong>Keren Zhou</strong><br /> In the last 10 years, graphics processing units (GPUs) have become a critical component in high performance computing systems. For example, five of the top 10 supercomputers in the world today use GPUs to accelerate the performance of applications in various domains. These systems must be designed to avoid common GPU performance problems, and identifying specific performance problems can be challenging.</p> <p>Working with his advisor John Mellor-Crummey and others, Zhou has taken the lead in developing performance tools for GPU-accelerated supercomputing to help programmers detect program inefficiencies and provide optimization advice.</p> <p>Their work has already been well received in academia and industry. Zhou and his colleagues have published three papers in top-tier conference proceedings. They are also collaborating with GPU vendors, including AMD, Intel, and NVIDIA; they have submitted a collection of bug reports and offered advice about how to improve their GPU hardware and software measurement interfaces.</p> <p><strong>About the ACM-IEEE CS George Michael Memorial HPC Fellowship</strong><br /> The ACM-IEEE CS George Michael Memorial HPC Fellowship is endowed in memory of George Michael, one of the founding fathers of the SC Conference series.

Smith</a> of the University of Arizona are the recipients of the <a href="https://awards.acm.org/hpc-fellows">2019 ACM-IEEE CS George Michael Memorial HPC Fellowships</a>. Fernando is recognized for his work on high performance algorithms for applications in relativity, geosciences and computational fluid dynamics (CFD). Smith is recognized for her work developing a novel dynamic rerouting algorithm on fat-tree interconnects. The Fellowships are jointly presented by ACM and the IEEE Computer Society.</p> <p><strong>Milinda Fernando</strong><br /> New discoveries in science and engineering are partially driven by simulations on high performance computers―especially when physical experiments would be unfeasible or impossible. Fernando’s research is focused on developing algorithms and computational codes that enable the effective use of modern supercomputers by scientists working in many disciplines</p> <p>His key objectives include: making making computer simulations on high performance computers easy to use (by using symbolic interfaces and autonomous code generation); portable (so they can be run across different computer architectures); high-performing (because they make efficient use of computing resources); and scalable (so that they can solve larger problems on next next-generation machines).</p> <p>Fernando’s work has enabled improved applications in areas of computational relativity and gravitational wave (GW) astronomy. In the universe, when two supermassive black holes merge, they bring along corresponding clouds of stars, gas and dark matter. Modeling these events requires powerful computational tools that consider all the physical effects of such a merger. While recent algorithms and codes to develop simulations of black hole mergers have been developed, they were limited because they could only handle simulations when the masses of the two black holes were comparable. Fernando developed algorithms and code for mergers of black holes, or neutron stars, of vastly different mass ratios. These computational simulations help scientists understand the early universe as well as what is going on at the heart of galaxies.</p> <p><strong>Staci Smith</strong><br /> A general problem in high performance computing occurs when multiple distinct jobs running on supercomputers send messages at the same time, and these messages interfere with each other. This inter-job interference can significantly degrade a computer’s performance.</p> <p>Smith’s first research paper in this area, “Mitigating Inter-Job Interference Using Adaptive Flow-Aware Routing,” received a Best Student Paper nomination at SC18, the premiere supercomputing conference. Her paper had two goals: to explore the causes of network interference between jobs (in order to model that interference); and to develop a mitigation strategy to alleviate the interference.</p> <p>As a result of this work, Smith recently developed a new routing algorithm for fat-tree interconnects called Adaptive Flow-Aware Routing (AFAR), which improves execution time up to 46% when compared to other default routing algorithms. As part of her ongoing PhD research, she continues to develop algorithms to improve the performance and efficiency of HPC workloads.</p> <p><strong>About the ACM-IEEE CS George Michael Memorial HPC Fellowship</strong><br /> The ACM-IEEE CS George Michael Memorial HPC Fellowship is endowed in memory of George Michael, one of the founding fathers of the SC Conference series.

Gesenhues is being recognized for her work on finite element simulation of turbidity currents with an emphasis on non-Newtonian fluids. Höhnerbach is being recognized for his work on portable optimizations of complex molecular dynamics codes. The Fellowships are jointly presented by ACM and the IEEE Computer Society.</p> <p>Gesenhues’ work on turbidity currents may be a useful tool for scientists studying underwater volcanoes, earthquakes or other geological phenomena occurring on the sea floor. Fluids, including water, become turbid when the concentration of particles, such as sediment, rises to a particular threshold. Because of their density, turbid fluids move differently than non-turbid fluids—frequently cascading downward as they are impacted by gravity. The presence of turbid currents can indicate that mud and sand have been loosened from collapsing slopes, earthquakes, or other phenomena. For these reasons, scientists regularly place turbidity sensors on the sea floor to monitor geologic activity.</p> <p>A challenge of understanding turbidity currents is cataloging the range of possible movements a fluid may make based on the variables in its surrounding environment. For this reason, employing supercomputers, which can process trillions of possible permutations, is an effective approach. The objective of Gesenhues’ PhD project is to obtain a model for numerical simulation of turbidity currents that can predict the characteristics of such flows using non-Newtonian fluid behavior. Non-Newtonian fluids have a higher resistance to deformation than Newtonian fluids; for example, shampoo (a non-Newtonian fluid) loses its shape more slowly than water (a Newtonian fluid).</p> <p>Thus far, Gesenhues has developed a “solver” (a numerical model) for a 2D simulation of turbidity currents that has been implemented, established and verified. Recently, she augmented her 2D solver to a 3D model. Here, first tests on small 3D benchmark applications were made, including a column collapse.</p> <p>Markus Höhnerbach’s research focuses on creating simulations for many-body potentials in molecular dynamics (MD) simulations. MD simulations are an indispensable research tool in computational chemistry, biology and materials science. In an MD simulation, individual atoms are moved time-step by time-step according to the forces derived from so-called potential, which is the mathematical law that governs the interactions between atoms. The general idea of Höhnerbach’s PhD project is to develop methods and tools to make the implementation of MD simulations simple and correct by design while generating fast code for a multiple of platforms. For example, in his paper, “The Vectorization of the Tersoff Multi-Body Potential: An Exercise in Performance Portability,” he demonstrated the performance of a type of MD simulations in a wide variety of platforms and processors.</p> <p>Recently, Höhnerbach has been working with MD simulations for the adaptive intermolecular reactive bond order (AIREBO) potential, which is frequently used to study carbon nanotubes. Many believe carbon nanotubes hold great potential for the future of computer architecture. Höhnerbach wrote a code for the AIREBO potential that has achieved 3x to 4x speedups when performing realistic large-scale runs on current supercomputers.</p> <p>The ACM-IEEE CS George Michael Memorial HPC Fellowship is endowed in memory of George Michael, one of the founding fathers of the SC Conference series.

Smith is being recognized for his work on efficient and parallel large-scale sparse tensor factorization for machine learning applications. You is being recognized for his work on designing accurate, fast, and scalable machine learning algorithms on distributed systems.</p> <p>Shaden Smith’s research is in the general area of parallel and high performance computing with a special focus on developing algorithms for sparse tensor factorization. Sparse tensor factorization facilitates the analysis of unstructured and high dimensional data.</p> <p>Smith has made several fundamental contributions that have already advanced the state of the art on sparse tensor factorization algorithms. For example, he developed serial and parallel algorithms in the area of Canonical Polyadic Decomposition (CPD) that are over five times faster than existing open source and commercial approaches. He also developed algorithms for Tucker decompositions that are up to 21 times faster and require 28 times less memory than existing algorithms. Smith’s algorithms can efficiently operate on systems containing a small number of multi-core/manycore processors to systems containing tens of thousands of cores.</p> <p>Yang You’s research interests include scalable algorithms, parallel computing, distributed systems and machine learning. As computers increasingly use more time and energy to transfer data (i.e., communicate), the invention or identification of algorithms that reduce communication within systems is becoming increasingly essential. In well-received research papers, You has made several fundamental contributions that reduce the communications between levels of a memory hierarchy or between processors over a network.</p> <p>In his most recent work, “Scaling Deep Learning on GPU and Knights Landing Clusters,” You’s goal is to scale up the speed of training neural networks so that networks which are relatively slow to train can be redesigned for high performance clusters. This approach has reduced the percentage of communication from 87% to 14% and resulted in a five-fold increase in speed.</p> <p>The ACM/IEEE-CS George Michael Memorial HPC (GMM) Fellowship is endowed in memory of George Michael, one of the founding fathers of the SC Conference series.
