multi-core

I just setup a Extra Large Heavy Computation EC2 instance to throw it at my Genetic Algorithms problem, hoping to speed up things.

This instance has 8 Intel Xeon processors (around 2.4Ghz each) and 7 Gigs of RAM.

On my machine I have an Intel Core Duo, and matlab is able to work with my two cores just fine. On the EC2 instance though, matlab only is capable of detecting 1 out of 8 processors.

Obviously the difference is that I have my 2 cores on a single processor, while the EC2 instance has 8 distinct processors.

My question is, how do I get matlab to work with those 8 processors?

I found this paper, but it seems related to setting up matlab with multiple EC2 instances, which is not my problem.

Any help appreciated!
