Benchmarking a Beowulf Cluster - Page 3

mercthunder · #1 (**permalink**) 04-29-2009

Hi guys. I am trying to test my universities cluster using the Intel Linpack Benchmarking software. Let me say from the get-go that i am a Linux novice, and only recently learnt some Linux commands to have a play around, so if you can please keep the language simple

I have run a Linpack test as can be seen from the below terminal copy and paste. However, the test that i have currently run, i believe is just testing the avg GFLOPS for the current node i am on. What if i want to test the strength of a cluster of 3 nodes all working together? Would anyone happen to know what i would need to type in the command line in order to run a test on 3 nodes that i have logged into (all clustered by the university already). The nodes are all Xeon 64's, with 4 Gigs of ram each. Would really appreciate any help.

Code:

[******@beowulf linpack]$ ./xlinpack_xeon64
