You will find them at: http://www.scali.com/info/SHM-perf-8bytes-2007-12-20.htm http://www.scali.com/info/SHM-perf-128bytes-2007-12-20.htm Please note the tabs section at the bottom. You will have to use the horizontal scroll bar in order to see all the charts. Also, the 8-byte URL above does not start at the first tab, which is slightly confusing. The Y-Axis is sometimes time (usec), Bandwidth (1e6 bytes/sec), or message rate (1e6 messages per second). The hardware is dual socket Woodcrest, 3.00GHz, dual socket Clovertown, 2.66 and 3.00GHz. OS is SLES9. And, I am aware that the version of OpenMPI is quite old. Enjoy, Hakon
