Abstract

This paper describes an implementation of the LAM MPI suite on the top of the Virtual Interface Architecture.

The Virtual Interface Architecture (VIA) is an emerging standard designed by Intel, Microsoft, and Compaq aimed at the reduction of communication latency for cluster of workstations or system area networks.

Thanks to M-VIA, a Linux software module that emulates VIA and provides programmers of VIA APIs, it has been possible to develop an MPI implementation even in absence of a hardware VIA interface. Nonetheless, M-VIA module high optimization as well as VIA protocol simplicity permitted a reduction of latency time with respect to the use of the TCP/IP protocol on Ethernet network interfaces.
