Hi everyone! I am working with an astrophysical code that uses a lot of memory (RAM). Basically because of a 3D matrix that I have to define. I was working with 1G of RAM before and could run the code with a cube of 70^3 cells. Recently I bought a new super machine with 4g of RAM and I am using the gcc 3.2 compiler on linux redhat 7.3. But I am not able to run more than 70^3 cells on this. Can anyone give me some clue?? I would think I should be able to do better no? Is this a linux kernel limitation or gcc or something else??

cheers,

Hektor
