I am wondering whether it is possible to compile the codes using MPICH-based compiler, keeping the multithread function. Thanks a lot</P> Fri, 20 Nov 2009 15:38:46 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Multithread-MPICH/m-p/880056#M9434 recrusader 2009-11-20T15:38:46Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Multithread-MPICH/m-p/880057#M9435 <DIV style="margin:0px;"></DIV> Hi,<BR /><BR />Please keep in mind that MPICH1 implementation is not thread safe, as it is clearly stated on its site.<BR />You may consider Intel MPI the latest version of which is thread safe (need to use the option "-mt_mpi").
