maximum memory 32bit fluent version

May 19, 2005, 05:33

Dear all!

Is it true that a 23 bit fluent version is only able to adress 2GB of RAM? My Linux workstation has 4GB available and I need more than 3GB for the next job...

What can I do?

Thanks a lot!

What about on a machine with windows and 2 cpu's?

Thanx for you replies.

I'm using a Linux-machine with a Athlon64 and Linux is able to handle 4GB RAM.

My question was why am I not able to start a fluent (fluent 32bit version for Linux!!) job with more than 2GB on my machine? I would also prefere a dual processor machine but it's not up to me...

thanx for you help

I think there is a version of Redhat Linux (Redhat Enterprise Linux WS)that will support 4GB memory on a 32bit machine,Try it !

Thanx Akin!

My Problem isn't the Linux version. My debian support's 4GB.

But my 32bit fluent version is not able to allocate more than 2GB of memory by using only one processor.

on 2 cpu machine if you run two process then u can use more than 2 gb ram, on my two cpu i have observed that in some cases i was using 2.9 gb ram (total ram was more than 3 gb), i guess on windows we can't start a single process that takes more than 2gb (i am not sure but i somewhere read this sort of thing)
