MCX is a GPU-accelerated, general-purpose, physically-accurate and feature-rich 3-D light transport simulator. It is one of the fastest simulators because it can use tens of thousands of GPU threads to simulate photons in parallel.

mtsieve is a framework wrapped around primesieve to distribute prime numbers to worker classes to do work with those prime numbers. The "mt" means that it is multi-threaded. The "sieve" means that the framework is typically used to eliminate candidate terms with small from a set of numbers. The numbers remaining after using mtsieve can then be used by programs such as llr and pfgw to test those numbers for primality. Another usage could be to use those prime numbers to test each for a specific characteristic, such as whether it is a Wieferich or Wall-Sun-Sun number. The framework is portable to any OS running on x86-64 and supports GPUs.

The Package is installable in GNU Octave and offers OpenCL support for parallelization of numerical computations. It is most effective for computations which are based on large vectors or n-dimensional arrays of numbers, and mostly (but not limited to) identical element-wise operations. The user can select which available OpenCL hardware and drivers are to be used. The Package offers new numeric data types with many built-in operations (e.g., overloaded operators). It is flexibly extendible by user-written OpenCL C programs. The Package does not, by itself, provide parallelization of higher numerical methods (like BLAS or LAPACK). The Package is also available from the corresponding Octave Forge webpage https://octave.sourceforge.io/ocl/index.html. More information on GNU Octave can be found at https://www.octave.org.

This kernel uses a discrete approach where the geometry is split into "atoms" at a fixed resolution (e.g. 1µm). The aim is to make full use of the parallel processing capabilities of modern graphics hardware.
