Hi, If you do not have the funds to pay for the scyld stuff there is an open source implementation called Bproc. We have been using it with our linux cluster here for a few year now. http://www.clustermatic.org/ Unfortunately the researchers at Los Alamos stopped Bproc development and are now working on something called XCPU take a look here: http://www.xcpu.org/ Bproc runs on our cluster with SUSE 9.1 just fine and it is rock solid. It will work for you if you are using gige as your interconnect. If you need infiniband, myranet, or some of the newer 2.6.15 or above kernels then you will need to look at xcpu. Hope this helps.

Hi!

We would like to build a cluster of multiple Opteron based computers. The usage is for scientific computing (multiple scientists running large processes usually at the same time... :-) Mainly computing but also some large flat file access, no DB stuff.

You might take a look at Penguin Computing's "Scyld".

http://www.penguincomputing.com

We hosted a talk by Penguin and Don Becker recently and are interested in the technology for HPC applications as you describe. They support Red Hat Enterprise now, but Don said they are working on SuSE.

Yes, this is the Don Becker of Ethernet driver fame and a co-inventor of Beowulf clustering.

Beowulf is exactly what we need. We actually had openMosix in mind, but the problem with that is that the 2.6 kernel is not yet ready for production use. And we don't think we can do with 2.4 anymore (we're not sure, but the guess is that it would cause more headaches). To be honest, it does not have to be SUSE, I just happen to like SUSE. Scyld sounds like the best option so far. We'll have to take a closer look at it (like the kernel version, pricing and all that).

We are using CONDOR on OpenSUSE 10.1 with AMD64 (not Opteron, but I don't see that mattering) in a very simple installation.
