Subject: Question on a high performance platform for Matlab

We are going to acquire a compute server for our lab which will support
Matlab.

We have some fairly large, but parallizable problems so we are looking at
64-bit systems. Currently, we are considering a system using 4 Xeon 6-core
processors under Linux or Windows server. We might also consider Sun

Does anyone have experience that would indicate that Matlab runs better or
with fewer problems on one or the other?

I don't want to start an OS war. I use both Linux and Windows and suffer
equally with both.

Marco,

I'm running a cluster of 64-bit HP xw8600 Workstations each with 8 cores and 16 GB physical ram, high-end graphics adapter, 2x300GB hard drives running WinXP Professional x64 Edition and 64-bit Matlab.

The only advantage I see is the additional memory address space. We can work with somewhat larger files but nothing spectacular. Speed is not dramatically increased.

I'm not very impressed.

A few years ago at a hedge fund I had clients hitting my Matlab apps on a 32-bit Linux box that seemed much faster.

Anecdotal input at best but that has been my experience.
