Hello,
Make sure the MPI_TAG being used with mpi calls is not becoming a negative
value.

The error message is self explanatory, the application calls MPI_Recv with
an invalid TAG. The MPI standard defines a valid tag as a positive integer
between 0 and the value of the MPI_UB_TAG attribute on MPI_COMM_WORLD. At
this point it seems plausible this is an application issue.

Hi,
Good morning.
I am using openmpi/4.0.3 on Compute Canada to do 3D flow simulation. My grid
size is Lx*Ly*Lz=700*169*500. It worked quite well for lower resolution.
However, after increasing my resolution from Nx*Ny*Nz=64*109*62 to 256*131*192,
openmpi reported errors as shown below:
