You will find them at:

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
