The code stops stoichastically, mainly at one function call. When I eliminated this call it stops at other positions.</P><P>I am not sure if the stop is due to Fortran or to MPI. I have tried to move to OpenMP, but I am not sure if this is possible due to assumed-size arrays.</P><P>If this is a known problem with MPI, can I move to ifx+MPI or back to older ifort and/or MPI versions? This is&nbsp;a very severe problem in my case, as the code has to be restarted regularly.</P><P>I have used the MPI debugger at the highest level, but I did not find any understandable error code.</P><P>Best regards</P><P>Anders_S</P> Sat, 02 Sep 2023 20:06:49 GMT Anders_S_1 2023-09-02T20:06:49Z https://community.intel.com/t5/Intel-Moderncode-for-Parallel/MPI-stops-stoichastically/m-p/1519990#M8208 <P>Hi</P><P>I have used MPI to parallelize my code using ifort and Windows.
