→Means of parallelisation on GPUs
OpenMP API specification for parallel programming provides an application programming interface (API) that supports multi-platform shared memory multiprocessing programming in C, C++, and Fortran, on most platforms. It consists of a set of compiler directives, library routines, and environment variables that influence run-time behavior.
Benefits of OpenMPI:. Why to choose over GPU kernel model?OpenCl is highly portable-supports multi-core, popular vectorization and it's instructions supported on wide verity GPU-allows for "teams of devices across all platforms.threads"-portable between various plaforms-heterogeneous memory allocation and custom data mappers
