[mpich-discuss] mpich on Mac os x

[Reem Alraddadi]

Hi all,
I am using mpich-3.0.4 on Mac os x version 10.7.5 to run FLASH code. It
works fine in the beginning of the run and then I got the following error:

Fatal error in MPI_Comm_create: Other MPI error, error stack:

Is there a way to fix that ?

Thanks,
