Hi, Since CFD is Hardware-intensive application, and also I work with fluids I thought that this site would be the best place to ask this: With a bunch of friends, we are planning to buy and old server (IBM Xseries with 8 Xeon´s) in order to run CFD on it. Here´s my question. If those Xeon´s are 32 bits processors, but that server supports up to 16GB RAM, how I have to configure the OS (linux 32bit) in order to use more than those famous 4GB associated with the 32bits systems? I hope I was clear... I´ll have 16GB RAM in a 32bit system, so can I use the full power of the 8 Xeons and all that RAM?

Thanks a lot and sorry for my argentinian english. P.S: also I don´t want a full explanation. I don´t want to bother you. Just tell me if it´s posible or will be a waste of money.

Your Agentinean English is much better than my Tennessee Spanish! : )

Sorry I don't know the answer to your question. I hope you can do the project.

LOL! Thank you otd!

You cannot allocate more than 4gb per processor. The advantage of 8 Xeons is that you will be able to run parallel processing (8 nodes). As a consequence available RAM will be split among those 8 nodes.

More clear than water, thanks Krzysztof. Now I really want to buy that server!
