Data Writing Problem in Intel MPI

xuegy · October 10, 2016, 14:51

Hello all,

I compiled OpenFOAM 4.0 by Intel Parallel Studio 2017 in Ubuntu 16.04. After a few tweaks I managed to compile that

Everything is OK if I run it in single thread. However if I run it in parallel by Intel MPI it will crash after the first data is written. For example, if I choose to write every 0.1s, it will write 0.1s data and crash at exactly after 0.1s. Everytime I got similar messages from the terminal:

Fatal error in PMPI_Waitall: Other MPI error, error stack:
PMPI_Waitall(405)...............: MPI_Waitall(count=6, req_array=0x1d13f00, status_array=0x1) failed
MPIR_Waitall_impl(176)..........: fail failed
PMPIDI_CH3I_Progress(623).......: fail failed
pkt_RTS_handler(317)............: fail failed
do_cts(662).....................: fail failed
MPID_nem_lmt_dcp_start_recv(288): fail failed
dcp_recv(154)...................: Internal MPI error! cannot read from remote process

My MPI version: Intel(R) MPI Library for Linux* OS, Version 2017 Build 20160721
Anybody know how to solve it? Will it be a bug from the new version of Parallel Studio?

Hi,
I am also facing the same problem in OF-5.0. Did you manage to solve it?
