The more services you run on your cluster node (gmond, sendmail, etc.) the less performance is available for number crunching, but at the same time, administration difficulty increases. For example, if you turn off postfix/sendmail, you'll no longer get automated e-mails from your system to alert you to a problem.
My question is this: how extreme do you go in disabling non-essential services on your cluster nodes? Do you turn off *everything* that's not absolutely necessary, do you leave somethings running to make administration easier? I'm curious to see how everyone else has their cluster(s) configured. -- Prentice _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
