Dear Bernard,

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.
