Hello,
I have a setup of Infiniband network where we are testing the performance of FDRs. I have two FDRs on the sender and one FDR on each receiver. There are two receivers. The idea is to run parallel sends from the sender on each FDR and receive it at receiver. We were trying mvapich, but mvapich stated that they clearly don't support such a network.
I was wondering if Intel MPI support such a network. And if we can do something like:
mpirun -n 2 -hosts Sender,Receiver1 -env MV2_IBA_HCA=mlx4_0 ./exec : -n 2 -hosts Sender,Receiver2 -env MV2_IBA_HCA=mlx4_1 ./exec
where mlx4_0 and mlx4_1 are the ids of the FDR cards. So I am trying to run ./exec parallel on different FDR cards to send data to both the receivers at the same time.
Is this possible using Intel MPI. If someone has a similar setup then please let me know.
Thanks,
Santak
