| ＢＢＰ＿ＰＶＭ是为北京航空航天大学计算机系基于总线桥协议的异构可扩展并行计算机群系统ＢＢＰ＿ＳＰＣ（ｂｕｓｂｒｉｄｇｅｐｒｏｔｏｃｏｌ－ｓｃａｌａｂｌｅｐａｒａｌｅｌｃｏｍｐｕｔｅｒ）研制的ＰＶＭ版本．ＢＢＰ＿ＰＶＭ以总线桥多机互联协议的消息传递层子协议（ＢＢＰ＿ＭＰＬ）为虚拟机内各处理机间的通讯协议．ＢＢＰ＿ＭＰＬ是在ＢＢＰ可靠链路的基础上实现的精简和可靠的机间通讯协议，ＢＢＰ＿ＭＰＬ的采用有效地降低了通讯过程中报文应答、重发和动态缓冲区管理的开销．ＢＢＰ＿ＰＶＭ与ＰＶＭ３．３．４及其以上版本兼容． |

| Abstract: |
| The BBP_PVM is a dialect of PVM for a scalable parallel computer cluster system that based on Bus-Bridge-Protoc01．The inter-machine communication protocol the BBP-PVM is called BBP-MPL，the message passing layer protocol of the bus bridge pro-toc01．The BBP-PVM is compatible with the original PVM version 3．3．4 and above，but it has a more effective communication mechanism than the original version． |
| Key words: Bus bridge protocol reduced communication protocol scalable parallel computer cluster parallel virtual machine |
