full performance and parallelism of modern hardware (both CPUs and GPUs) to enable querying of multi-billion row datasets in milliseconds, without the need for indexing, pre-aggregation, or downsampling. HeavyDB can be run on hybrid CPU/GPU systems (Nvidia GPUs are currently supported), as well as on CPU-only systems featuring X86, Power, and ARM (experimental support) architectures. To achieve maximum performance, HeavyDB features multi-tiered caching of data between storage, CPU memory, and GPU memory, and an innovative Just-In-Time (JIT) query compilation framework.\u003c/p\u003e\n\u003cp dir=\"auto\"\u003eFor usage info, see the \u003ca href=\"https://docs.heavy.ai/\" rel=\"nofollow\"\u003eproduct documentation\u003c/a\u003e, and for more details about the system's internal architecture, check out the \u003ca href=\"https://heavyai.github.io/heavydb/\" rel=\"nofollow\"\u003edeveloper documentation\u003c/a\u003e.

engine that leverages the full performance and parallelism of modern hardware (both CPUs and GPUs) to enable querying of multi-billion row datasets in milliseconds, without the need for indexing, pre-aggregation, or downsampling. HeavyDB can be run on hybrid CPU/GPU systems (Nvidia GPUs are currently supported), as well as on CPU-only systems featuring X86, Power, and ARM (experimental support) architectures. To achieve maximum performance, HeavyDB features multi-tiered caching of data between storage, CPU memory, and GPU memory, and an innovative Just-In-Time (JIT) query compilation framework.</p> <p dir="auto">For usage info, see the <a href="https://docs.heavy.ai/" rel="nofollow">product documentation</a>, and for more details about the system's internal architecture, check out the <a href="https://heavyai.github.io/heavydb/" rel="nofollow">developer documentation</a>.

Certain dependencies such as Thrift, Blosc, and Folly must be built as they either do not exist in the default repositories or have outdated versions. A prebuilt package containing all these dependencies is provided for Ubuntu 18.04 (x86_64). The dependencies will be installed to <code>/usr/local/mapd-deps/</code> by default; see the Environment Variables section below for how to add these dependencies to your environment.</p> <div class="markdown-heading" dir="auto"><h3 tabindex="-1" class="heading-element" dir="auto">Ubuntu 16.04</h3><a id="user-content-ubuntu-1604" class="anchor" aria-label="Permalink: Ubuntu 16.04" href="#ubuntu-1604"><svg class="octicon octicon-link" viewBox="0 0 16 16" version="1.1" width="16" height="16" aria-hidden="true"><path d="m7.775 3.275 1.25-1.25a3.5 3.5 0 1 1 4.95 4.95l-2.5 2.5a3.5 3.5 0 0 1-4.95 0 .751.751 0 0 1 .018-1.042.751.751 0 0 1 1.042-.018 1.998 1.998 0 0 0 2.83 0l2.5-2.5a2.002 2.002 0 0 0-2.83-2.83l-1.25 1.25a.751.751 0 0 1-1.042-.018.751.751 0 0 1-.018-1.042Zm-4.69 9.64a1.998 1.998 0 0 0 2.83 0l1.25-1.25a.751.751 0 0 1 1.042.018.751.751 0 0 1 .018 1.042l-1.25 1.25a3.5 3.5 0 1 1-4.95-4.95l2.5-2.5a3.5 3.5 0 0 1 4.95 0 .751.751 0 0 1-.018 1.042.751.751 0 0 1-1.042.018 1.998 1.998 0 0 0-2.83 0l-2.5 2.5a1.998 1.998 0 0 0 0 2.83Z"></path></svg></a></div> <p dir="auto">HeavyDB requires a newer version of Boost than the version which is provided by Ubuntu 16.04.
