_xe_2020_edition on Windows 10. When I run the mpi fortran program,I found some problems.The function
MPI_BARRIER(MPI_COMM_WORLD) can not run in two computers. When the function MPI_BARRIER is executed, the program is no longer executed. However it can be run on one computer. Thanks for your help.

HI,
Could you please let us know the error you were facing while using MPI_BARRER?
Please export I_MPI_DEBUG=10 while collecting the logs.
Also please mention which interconnect and the provider you were using.
Regards
Prasanth

Hi,
Glad your issue got resolved. It was not related to MPI_BARRIER but might be due to the command line you have used while trying to launch across multiple nodes.
Please let us know if you have any further questions else, we can close the thread,
Regards
Prasanth
