Introduction » RDMA Handle Manager

RDMA handles backed by MPI.

The RDMA handle manager component vt::rdma::Manager, accessed via vt::theHandleRDMA() is a component that allows data to be transferred between RDMA handles, which are persistent objects with underlying memory registered with MPI.

RDMA handles can either be node- or index-level, depending on whether they belong to an objgroup or collection. A handle provides an interface to calling get/put/accum to access the backing MPI implementation.
