Task manager looks like all threads are maxed out and getrf never returns.</P> <P>The&nbsp; matrix size is quite small 2763x2763. But can be up to 10000 square.</P> <P>If I call mkl_set_num_threads_local(1) before entry it fixes the issue but then getrf is then only using one thread.</P> <P>I am using MKL 11.3 with mkl_intel_thread_dll.lib on Windows 64 bit</P> Wed, 14 Feb 2018 14:33:33 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/getrf-hangs-when-using-intel-threads-in-calling-application/m-p/1138849#M26174 Andrew_Smith 2018-02-14T14:33:33Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/getrf-hangs-when-using-intel-threads-in-calling-application/m-p/1138850#M26175 <P>Andrew, we made many updates wrt this routine since 11.3.* ( you may see many improvements into MKL 2017/2018 bug fix lists). could you try the latest MKL 2018 u1 or give us&nbsp; the reproducer and we will check this case with the latest version?</P> <P>-Gennady</P> Wed, 14 Feb 2018 16:00:10 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/getrf-hangs-when-using-intel-threads-in-calling-application/m-p/1138850#M26175 Gennady_F_Intel 2018-02-14T16:00:10Z
