https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/dgemm-vs-cblas-dgemm/m-p/883909#M9859 Hello,<BR /><BR />I'm doing some performance benchmarks on Intel's mkl right now and I noticed some unexpected issues. When using dgemm_() function instead of cblas_dgemm() on the same matrix I get around 4 times fewer Gflop/s. It's the same either with the non-parallel and parallel version. <BR /><BR />Did someone experience similiar things or could probably point me to a possible failure?<BR /><BR />Thanks<BR /> Thu, 22 May 2008 17:38:18 GMT cutio 2008-05-22T17:38:18Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/dgemm-vs-cblas-dgemm/m-p/883909#M9859 Hello,<BR /><BR />I'm doing some performance benchmarks on Intel's mkl right now and I noticed some unexpected issues.
