If you write code that does some math, but the actual math is implemented in external libraries. Many machine learning developers fall into this category, for the same reason they’re OK using Python and similarhigh-levelbut slow languages for their job. Some C++ folks are happy with vectoriz...
Alternatively, developers may choose to target a single instruction set without any runtime overhead. In both cases, the application code is the same except for swapping HWY_STATIC_DISPATCH with HWY_DYNAMIC_DISPATCH plus one line of code. See also @kfjahnke's introduction to dispatching. ...
Libraries written in C/C++ enable developers to write SIMD-hardware-oblivious application code and create code for specific SIMD extensions with little overhead. The separation into SIMD-hardware-oblivious code and a SIMD abstraction library reduces complexity and makes it...
In particular the library supports following CPU extensions: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX and AVX2 for x86/x64, VMX(Altivec) and VSX(Power7) for PowerPC, NEON for ARM. The Simd Library has C API and also contains useful C++ classes and functions to facilitate access...

These educational materials are for native app developers, familiar with C/C++ programming and with a basic knowledge of SIMD. TOPIC 1 Learning Objective Optimize Your Programs Learn how to code better so compilers can auto-vectorize for you. ...
Thread level parallelism is a current challenge for both hardware designers and software developers, but data level parallelism is another way to improve performance in many applications. The current state-of-the-art micro architecture include many functional units devoted to exploiting data-level ...
He has contributed to the development of some of the world’s fastest computers, and the software tools that make that performance accessible for programmers. James has shared this passion in classes, webinars, articles and has authored eight books for software developers. James enjoyed 10,001 ...
(something that Emscripten currently supports). Asm.js is not designed to be written by hand, and developers should write their apps in C/C++ and compile to JavaScript to use this implementation. The details of this are outside the scope of this paper. For more information s...
Reciting in the appended claims that a structure is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. § 112(f) for that claim element. Accordingly, none of the claims in this application as filed are intended to be interpreted as having means-plu...
