Tying in another recent discussion on the list, "root access" is actually one of the places I've seen some success using Cloud for HPC. It costs more, it's virtualized, and you usually can't get HPC-specialized hardware, so it's obviously not a silver bullet for all kinds of systems research... but on the other hand, you're free of sysadmin tyranny and can experiment as much as you like. And none of the other users will scream at you when they learn you were responsible for killing their jobs, *again*. As a tyrannical sysadmin myself ;-) , I've helped some of my users build ephemeral cloud clusters and shared configuration management scripts so their cloud systems "feel" a lot like the in-house system. A few times this has even resulted in changes we've pulled back into the shared cluster, as sudo-able commands or job options. (I one had the "pleasure" of helping to clean up a small cluster where over a third of the users had unlimited sudo rights. Only time I've ever seen users made *happy* by the introduction of a ticketing system and change management...) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (Darwin) iQIcBAEBAgAGBQJRcD9EAAoJEIZxePsWaJFj+oMQAJwZaeMAVRAQwSw5ErWHCqnM IxL1P5DkVoiHlbksZGUBzpljr9XPpAOG+mUtimzM5gjtQIOmQpMwoXoJ6bomQPND 5KK3HET1T48XRte2/2KX7o2wj/QUsaDYVysRtZnpA/Sk15uusjbSNGZ+BdNU1Vc6 NNEt7nFJFRUjdsq1Jh3qFoLfIretqJF2+nemr7FyZsUXfmgY1Ik16wSM0LEfST56 tp96PqvhyusEVDorAOSyiKPwXEXTBpMsvh4rTojQrwws7RsF+rS4L613WdJJBfid c3TJzX/GNznoPSjBbxsz4kDlDZwwmLD2Gwp3heNBH7XqDIIvnDIIE+ln/NjjJlO7 pXyAWUboVpOAZ7q/GosIX/2LCsgHzLHRn3dHUqiKpthzvGJS6h9afvvZCTVQfijK qg52SRzvLff8jydBybCisIy43bpD7kmWwEwsjfJHCo45RTi79e1YxtpaxXAcJOAr OTEkOd5bvfh9kHhrJ/BCL/Je4IegOQ5HwXxbR852ZirGNDJL536fOY2npJe9yROQ IQ81fBHgN6Cl8o1NOjYjk8Xma6WbWklVySNKw29Zc1Yv+v4VAKaHvzrkmRxoH8b0 TteEiyYD7f6sCn7TiNBLZQRBV7Yj1LEY5L7DGoV0Iky+mUy5Pe7qW/+xUMLuychL 0mZJ3zYOrjqq8OE+prUM =Wh2D -----END PGP SIGNATURE----- _______________________________________________ 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
