GROMACS is a versatile package to perform molecular dynamics, i.e. simulate the Newtonian equations of motion for systems with hundreds to millions of particles.
It is primarily designed for biochemical molecules like proteins, lipids and nucleic acids that have a lot of complicated bonded
... [More] interactions, but but thanks to its speed, many groups also use it for research on non-biological systems, e.g. polymers.
Speed is one of the key features that makes GROMACS particularly attractive. Thanks to the strong emphasis on bottom-up performance tuning: hand-tuned CPU SIMD kernels are available for most CPU architectures, CUDA-and OpenCL-based GPU acceleration together with efficient multi-threading and neutral-territory domain-decomposition with MPI SPMD parallelization is supported.

libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors which uses SIMD instructions (MMX, SSE2, etc.) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4x as fast as the unmodified version of libjpeg, all else being equal.

libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but the TigerVNC and VirtualGL projects made numerous enhancements to the codec, including improved support for Mac OS X, 64-bit support, support for 32-bit and big endian pixel formats (RGBA, ABGR, etc.), accelerated Huffman encoding/decoding, and various bug fixes. The goal was to produce a fully open source codec that could replace the partially closed source TurboJPEG/IPP codec used by VirtualGL and TurboVNC. [Less]
Pixman is a low-level software library for pixel manipulation, providing features such as image compositing and trapezoid rasterization. Important users of pixman are the cairo graphics library and the X server.
VirtualGL redirects 3D commands from a Unix/Linux OpenGL application onto a server-side 3D graphics card and converts the rendered 3D images into a video stream with which remote clients can interact to view and control the 3D application in real time.
Vecmathlib provides efficient, accurate, tunable, and most importantly vectorizable math functions such as sqrt, sin, or atan.
The library is implemented in C++, and intended to be called on SIMD vectors, e.g. those provided by SSE, AVX, or available in Power7 and Blue Gene architectures. The
... [More] same algorithms should also work efficiently on accelerators such as GPUs. Even without vectorization, vecmathlib's algorithms are efficient on standard CPUs. [Less]
