Hey folks, I just went through the archives trying to find some info on this but did not come up with much other than it seems there are a few experts here on the list. I have no experience with clustering and have just taken over a Stem Cell Research Lab that has a Grid Engine cluster. I have not yet dug into the details of Grid Engine (only been here a week now) but am just trying to get up to speed on clustering in general. I was just looking at Red Hat's site and they have this HPC thing http://www.redhat.com/promo/mrg/ but damned if I can find any actual details on it there - that data sheet they link to is just a bunch of marketing gobble-de-gook as far as I can make sense of it anyway. Quick question : what are Red Hat using to do that, and can CentOS do the same thing? How hard is it to configure? How does it compare to Grid Engine? I have to say I'm a bit hesitant about Grid Engine because of the whole Oracle takeover. I just don't trust Oracle. Basically I'd like to get up to speed really quickly on different clustering technologies, and maybe even set up a CentOS (or Scientific) based cluster in a sandbox to play with. I guess - looking for reading to get up to speed on clustering, and wondering what my options are with CentOS, RHEL and Scientific. thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"
