I posted something the other day in response
to somebody else's question but I think I should
have actually started a thread - sorry for the
duplication!

My quesstion is:
I want to run a large simulation on an
Intel machine and I was wondering just how
much memory I could access in one process?

The machine is a 4 CPU Xenon machine with
4 Gb of RAM and I was planing on using
a 2.4 kernel with gcc and glibc.

Is it true that I can only use 2 Gb -- that's
what somebody told me, but they're not exactly
Linux gurus! If this is so, does BSD of Solaris
on Intel get me around these limitations perhaps?

Thanks
Shane

Yep, the 2.4 kernel supports up to 4 GB of RAM.
