I'm not sure how that's handled at the IB layer, but the source may be

than allowed by an int. See the function's signature:
int MPI_File_read_all(MPI_File fh, void *buf, int count, MPI_Datatype datatype,
MPI_Status *status)

Hi David / users,
Thanks for your mail and suggestion.

When I start program, without doing anything, nodes other than master keep
waiting for the corresponding MPI_Bcast call and keep taking nearly 50% CPU
while idle. When I MPI_Bcast the variable
