The deep computing messaging framework

摘要: We present the architecture of Deep Computing Messaging Framework (DCMF), a message passing runtime designed for Blue Gene/P machine and other HPC architectures. DCMF has been to easily support several programming paradigms such as Message Passing Interface (MPI), Aggregate Remote Memory Copy (ARMCI), Charm++, others. This is made possible provides an application interface (API) with active messages non-blocking collectives. being open sourced layered component based multiple levels abstraction, allowing members community contribute new components its design at various layers. The can be extended architectures through development specific implementations classes. production on takes advantage direct memory access (DMA) hardware offload work achieve good overlap computation communication. take fact that node symmetric multi-processor four cache-coherent cores use multi-threading optimize performance collective network. also evaluation show it delivers close limits.
