Subject: [OMPI devel] RDMA with non-contiguous payload
From: Sebastian Rinke (s.rinke_at_[hidden])

Dear all,

Playing around with GPUDirect v1 and Infiniband I noticed that once the payload is non-contiguous no RDMA is used at all.
Can anybody confirm this?

I'm using Open MPI 1.4.3. If the above is true, has this behavior changed with later versions of Open MPI?

Thanks a lot.
