Cluster-of-Workstations

PVM provides a de facto standard for parallel programming in clusters-of-workstations environment. The PVM communication performance over the 640 Mbps ATOMIC LAN has been dramatically improved using the ATOMIC user-level protocol.

The PVM3.3 communication performance over the ATOMIC LAN.

31 Mbps throughput using the regular mode (through the pvmd)
65 Mbps throughput using the direct mode (over kernel TCP)

Improve PVM communication performance over the ATOMIC LAN.

Separate PVM control message and PVM data transfer.
- Control message takes regular mode (through the pvmd over kernel UDP).
- Fast data transfer using user-level reliable data protocol ( ATP ) over Myrinet API.
164-Mbps PVM point-to-point throughput over the ATP.

ATOMIC-PVM software release: atomic-pvm3.tar.Z

Improve PVM collective communication performance.

Uses highly efficient ATOMIC link-layer multicast.
