OpenMP-Parallelized LU Decomposition Matrix Solver

JDFI — Thu, 23 Sep 2021 15:43:20 GMT

Hi,

Is there an OpenMP-Parallelized LU Decomposition Matrix Solver available in MKL library? If yes, is there any guidance link on how to use it?

Thanks,

JDFI

Yes, LU decomposition routines are threaded by OpenMP. You may take a look at this MKL Dev Guide page: https://software.intel.com/content/www/us/en/develop/documentation/onemkl-linux-developer-guide/top/managing-performance-and-memory/improving-performance-with-threading/openmp-threaded-functions-and-problems.html#openmp-threaded-functions-and-problems_LAPACK

Hot to Link- see a number of examples show how to do that

or check MKL Linker Adviser - https://software.intel.com/content/www/us/en/develop/tools/oneapi/components/onemkl/link-line-advisor.html

check "Improving Performance with Threading " chapter from Dev Guide :
