| The ''ifort'' compiler with flag ''-mkl'' will compile and link to the threaded MKL libraries. Thus you should test in the threaded parallel environment, and export the number of slots to the ''MKL_NUM_THREAD'' environment variable. Remember to use our templates for threaded jobs which can be found in ''/opt/templates/slurm/generic/threads.qs'' as a starting point. Here is a simple ''test.qs'' based on the ''threads.qs'' template. | The ''ifort'' compiler with flag ''-mkl'' will compile and link to the threaded MKL libraries.
