Zero-copy MPI Based on Cluster Computing Communication Library HPCL_USTB
Jue Wang · Jisuanji gongcheng · 2006
It is an effective way to advance the cluster system efficiency that implements the MPI functions efficiently based on those various cluster low-level communication libraries.MPI_HPCL(Massage Passing Interface Based HPCL_USTB) is just an implementation of zero-copy MPI on the top of a cluster low-level communication library named HPCL_USTB(High Performance Communication Lib of USTB).It is capable of managing pin-down memory and avoiding deadlock.MPI_HPCL realizes the characteristics of good efficiency,safety and reliability by adopting some methods,such as separating the control of the send/receive pin-down memory and using the delayed queue.
