Hi Jeff,
thanks for you reply. I did understand previous questions about RDMA. Ever
with SKaMPI, i tried to run with mpi_leave_pinned = 1, as you have
suggested. But also in this case, execution time is very similar to
previous case.
Does it means that SKaMPI, reallocates buffer every time ? For
Note that "eager" RDMA is only used for short messages -- it's not
