[mpich-discuss] Fatal error in PMPI_Bcast:

[Fujun Liu]

The cpi also does not work. There is no error message, but it takes forever:

xxxx at query:~/MPI$ mpiexec -n 2 -f machinefile
/home/netlab/MPI/mpich2-build/examples/cpi
Process 1 of 2 is on query
Process 0 of 2 is on trigger

I think my two hosts are still trying to communicate to each other. Any
suggestions?

Best wishes,
