Intel MPI:Dapl async event error

517 Views

Hi,

I am using cluster checker 1.2 and intel mpi 3.2. While running hpcc test with cluster checker for 33 nodes 8 process per node, sometimes I receive error "dapl async_event QP (0x2aaab439ff50) ERR 1" and execution stucks then after.

From different online forums, I came to know that this error comes when some data is received but application has not posted buffers for the same.

For other MPIs they have suggested some environment settings to resolve this issue.

For Mvapich2, MV2_PREPOST_DEPTH<=59
For HPMPI, -e MPI_UDAPL_MSG1=1

Can you please suggest similar kind of solution for intel mpi?

Thanks in advance.

Regards,
Jolly
