Hi,
We tried to run the Reduce_scatter test(given in IMB_3.2.1) on our
customized OFED, the command used and the error thrown is given below...
*command:*
mpirun --prefix /usr/local/ -np 3 --mca btl openib,self,sm -H
192.168.0.157,192.168.0.167,192.168.0.177 --mca orte_base_help_aggregate 0
/root/subash/imb/src/IMB-MPI1 reduce_scatter
*error:*
[localhost.localdomain:06040] *** An error occurred in MPI_Reduce_scatter
[localhost.localdomain:06040] *** on communicator MPI COMMUNICATOR 3 SPLIT
FROM 0
[localhost.localdomain:06040] *** MPI_ERR_TRUNCATE: message truncated
[localhost.localdomain:06040] *** MPI_ERRORS_ARE_FATAL (your MPI job will
now abort)
--------------------------------------------------------------------------
mpirun has exited due to process rank 1 with PID 6040 on
node 192.168.0.167 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------
We didn't get much of the information regarding this error... can you
please clarify the reason for that error..??
We were able to run all the remaining tests that were there in the intel
IMB bench mark tool, and the basic ping-pong tests and q-perf cases also...
Thanks for your reply..
