摘要： ：针对集群计算系统不同的底层通信库，高效率地实现MPI函数是提高集群应用系统效率的有效途径。MPI_HPCL(Massage Passing Interface Based on HPCL_USTB)就是在集群系统底层通信库HPCL_USTB(High Performance Communication Lib of USTB)的基础上实现的具有零拷贝支持的MPI系统。它能够有效地管理被锁定的存储空间，避免死锁现象，采用对发送和接收的锁定存储进行分开控制和延迟队列的策略，保证了零拷贝消息传送的高效率和安全可靠。

Abstract: 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.
