Clearly fwrite was called with invalid parameters, bu
Thanks,
About my MPI program bugs:
I used GDB and got the error:
Program received signal SIGSEGV, Segmentation fault.0: 0x003a31c62184 in
fwrite () from /lib64/libc.so.6
also error :
1: Program received signal SIGABRT, Aborted.0: I am rank 0, I have sent
4tasks out of total tasks1: 0x00
Previous versions would set mpi_yield_when_idle automatically when
oversubscribing a node. I assume this behavior was not intentionally
changed, but the parameter is not being set in cases of oversubscription,
with or without an explicit hostfile.
