Intel MKL (Math Kernel Library) is a library of optimized math routines for numerical computations such as linear algebra (using BLAS, LAPACK, ScaLAPACK) and discrete Fourier Transformation. The host code has blocking calls everywhere because this is in an MPI parallelized function and the localWorkSize is set as null to allow the gpu to choose the most "optimal" size. uniform 1 1 in let y = Mat . On many platforms, a specific native … A native event is an event specific to a specific hardware platform. For Fortran code ported to C in mechanical fashion, one may chose to retain 1-based indexing to avoid the need to transform loops. OpenBLAS is an optimized BLAS library based on GotoBLAS2. The device code is written using ANSI C extended with keywords for labeling data-parallel functions, called kernels, and their associated data structures .
