For this assignment I will be focusing on the Linear Algebra routines. I will use workshop six to demonstrate how BLAS can be used to significantly speedup the calculations and compare them to other parallelization methods. <u>Compared to</u>#Serial#Cilk#Cilk with array notation and reduction#Cilk with SIMD and reduction#MKL CBLAS level 3#CUDA CUBLAS level 3#TBB#OpenMP '''Intel Math Kernel Library''' MKL provides highly vectorized and threaded Linear Algebra, Fast Fourier Transforms,Vector Math and Statistics functions. Intel MKL uses industry standard APIs.This means that developers would have to make minor changes to their programs whenswitching to MKL. '''Intel MKL gives the developer control over the necessary trade-offs''' #Result consistency vs performance#Accuracy vs performance Intel MKL is also compatible with your choice of compilers, languages, operating systems, linking and threading models. One library solution across multiple environments means only one library to learn and manage.
