Abstract

One approach to reduce the multi-layer overhead of TCP/IP is to bypass it, accessing the LAN directly from user level. Most existing implementations of such a shortcut rely on a polling mechanism, they either support a single-user enviromnent, or do not coexist with TCP/IP. In order to improve the PVM daemon network performance, we developed a new Direct Network Access (DNA) library for PVM and the Myrinet LAN, that bypasses and coexists with TCP/IP. The DNA includes a non-polling receive mechanism, an efficient mutual exclusion mechanism and a shared buffer management scheme, thus enabling operation in a time sharing environment. The paper describes the DNA and its integration in the PVM daemon, and presents performance results, which amount to a latency reduction of 18% for PVM tasks.
