Running across 64 nodes here at NCSA w/ no problems... If I understand it correctly, C3, even in parallel mode, is still somewhat serial, to assure scalability. Maybe one of the C3 folks can confirm my guesses here. (true parallel would probably run into some sort of resource limit since there's a single source point) ssh, rsh, and rsync have their own limitations, some of which I've run into before.

Hi John, C3 is developed and maintained my my team at ORNL.It has the capability of running commands across the entire cluster or any subset of nodes. It also has the capability of running across multiple clusters (subsets of each too) - all in a secure fashion. There is nothing "inside" C3 to prevent it from running on very large cluster farms. I have heard of it begin used across 200+ nodes -- however, we have only run on our mix of up to 128 boxes split on more than one cluster (there is some efficiency gained in doing this too...) 64-nodes is the largest "flat" cluster we have run across at ORNL. We are working on some techniques designed to scale (better performance) on clusters to 10,000's of nodes... I expect to have a release of this (perhaps not for 10k nodes, but something reasonable anyway) by the end of 2002. stephen John HEARNS wrote: > > I'm interested in OSCAR, and have been following the list > for a good couple of months now. > > I'm just looking over the C3 tool, mainly interested in > commands for running on all nodes in a cluster. > Can I ask how for C3 will scale? > Is anyone running it on very large farms (maybe 1000 nodes?) > > ------------------------------------------------------- > This sf.net email is sponsored by:ThinkGeek > Gadgets, caffeine, t-shirts, fun stuff. > http://thinkgeek.com/sf > _______________________________________________ > Oscar-users mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/oscar-users -- ------------------------------------------------------------------------ Stephen L.
