Hi,
I'm trying to dig into OpenMPI sources but have some problems. Can
anyone explain the logic of the following code from
mca/pml/ob1/pml_ob1_rdma.c please?
if(!mca_pml_ob1.leave_pinned) {
/* look through existing registrations */
btl_mpool->mpool_find(
his case, there is no

Anyone care to explain?
All I want is to see how non-eager RDMA can be used by ob1 if
leave_pinned is FALSE.

Okay, I tried Open MPI 1.3.3 and nothing has changed -- OpenIB RDMA
isn't used if mpi_leave_pinned is 0.
