We present the architecture of the Deep Computing Messaging Framework (DCMF), a message passing runtime designed for the Blue Gene/P machine and other HPC architectures. DCMF has been designed to easily support several programming paradigms such as the Message Passing Interface (MPI), Aggregate Remote Memory Copy Interface (ARMCI), Charm++, and others. This(More)
The MPI Forum has ratified extensions to MPI RMA with a new flexible and high performance passive target synchronization mechanism, new calls for window allocation and atomic operations executed on remote windows. In this paper, we explore an implementation of this new MPI-3.0 RMA interface on the Blue Gene/Q machine with performance results. We take(More)
