I've never had a cluster large enough to matter but I was thinking of running the Linpak-HPL benchmark (from the top500 site) just out of curiosity of knowing my actual teraflops. For one, it would tell me how much my Rmax/Rpeak so that I know how non-optimal my network and other infrastructure was.
Question: How difficult it is getting that benchmark to run? Was eager to know of opinions from sys-admins who've "been there, done that". If it was a horrendously difficult process I might just skip it. Some their tuning sections were scary. Are there any good pointers on tuning parameter selection or ready made makefiles? I had a Intel Nehalem processor and a regular Gigabit network. -- Rahul _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
