A large number of groups is pursuing high performance computing on commodity hardware. We could only find few reports of performance numbers for MPI on such systems.

• The Fast Messages Project [5] achieves MPI latencies of 19 s and a peak bandwidth of 17.3 MB/s on two SPARCstations 20/71 connected by a Myrinet Network.
• The NOW group [1] at Berkeley reports MPI latencies of 17 s between UltraSparc workstations connected with Myrinet Switches.
• Efforts by V. Gupta to build MPI on top of the unreliable AAL5 have announced ont the WWW (http://web.cps.msu.edu/ guptavi1/proj.html), but nothing has been published yet.
• S. Nog and D. Kotz present measurements of MPICH on TCP/IP with Fast Ethernet (http://www.cs.dartmouth.edu/reports/abstracts/TR95-273). They find latencies of 900 s for MPICH on Fast Ethernet between Pentiums P/100.
