Out of curiosity, is there the possibility of running a "swapless" compute-node? I mean most HPC nodes already have fairly generous RAM and once swapping to disk starts performance is degraded (severely?). Are there non-problem scenarios where one does desire swapping to disks? > D) Most current node chassis have hot-swappable disks, not hard to replace, > in case of failure. Hot-swappable disks are great on head nodes but on compute-nodes whenever I hear "redundant" or "hot swappable", I see it as an inefficiency. Or a excessive feature that could be traded off for a cost saving. (of course, sometimes hands are tied if the server comes with that feature "standard") What do others think? -- 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
