Dear Bernard,
My apologies. I'd be more careful about it in the future.
The following are answers to your questions:
1. Currently OSCAR does not support multiple distroes, in the very
near future we would be able to. So either Fedora Core 2 works, or
you can rebuild your cluster with Fedora Core 3.
2. You can install a x86 OS on AMD Opteron, however, you will only be
able to access max ~3GB of memory per process. If this is not a
concern for you, then you can try to install x86 OS. Of course if
you're starting from scratch, it is recommended that you install a
x86_64 OS.
Thanks for the clear explanation. I didn't know that the difference
between 32 and 64-bit machines is just the max memory access. In this
case I would try to use x86 OS first and see if it works.
But just in case should it fail, can I
1. use FC2 x86 OS for the original cluster but FC2 x86_64 for the new nodes?
or
2. Use FC2 x86_64 OS on an Intel 32 bit machine (so that I can use
x86_64 on the whole cluster)?
Thanks a lot for your help.

If Fedora Core 2 x86 works on your AMD dualcores, then this should be
pretty straightforward.
Cheers,
Bernard

Hi Bernard,
Thanks for the reply.
1. I've not tried FC2 on my AMD opteron. From the FC release notes, it
seems that it would work. Can I install FC3 on the new nodes if the
server is FC2?
2. I thought that I'd need x86_64 for the new nodes. Would x86 work on a
64-bit machine?
Thanks for any input.
