Hi every one!
After reading the FAQ about OFED, I knew that openMPI can collaborate with
RoCE. Moreover, using the RoCE make some overhead because the underlying
network layers. In my infiniband bandwidth testing, I get the 5Gbps using
IPoIB and 12Gbps using RDMA. The performance gap is huge for my application.
My question is: Could the OpenMPI use the RDMA raw api not via network
layer?!
Best regards
