Hi,
I have been trying out few sample examples in ULFM library. When I run one such
example with OpenMPI on a cluster with infiniband interconnect using 32 nodes,
512 processes
mpirun –np 512 –am ft-enable-mpi ./simpleagree
I get this error,
[btl_openib_endpoint.c:694:mca_btl_openib_endpoint_connected] Error posting send
But when I execute the same program with fewer nodes (till 8 nodes, 128
processes) it executes fine. I tried tuning the BTL parameters to tcp, sm,
self, openib but I get the same error. Can someone let me know if I’m missing
something here. Is this likely to be an issue with openmpi.
Thanks,
Murali
