Hello
I am presently running a huge code following the hydrodynamical evolution
of a system (in 2 dimentions). I store the quantities evolving (density,
velocity, pressure) into large 2-D arrays. Recently, I tried to make my
2-D arrays bigger (to study a bigger system) and eventually, I reached a
certain point where I was getting a "segmentation error". The only thing
I changed was the size of my arrays.
I deleted a few arrays that were redundant (making my code less user
friendly), and I found that I could slightly increase the size of my
arrays until I reached the "segmentation error".
Here are my questions: 1) Is there a maximum number of variables allowed
when using gcc? (from my experience I am guessing yes) 2) Is there a way
to increase the number of variables allowed when using gcc?
It sounds like you may have overflowed the stack. Could you try
increasing the stack size? I don't know how to do that though with gcc.
I had to check on the web real to see what you meant. I am a physicist
trying to program, and not a programmer trying to do physics :)
According to a web site, the default stack size on OS X is 8 MB. it is
possible that I have exceeded that. I am looking into ways of trying to
increase this.
