I used malloc to create my arrays instead of creating the in the stack. My program is working now but it is very slow.
I use two-dimensional arrays. The way I access element (i,j) is:
array_name[i*row_length+j]
The server that I use has 16GB ram. The ulimit -a command gives the following output:
time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         unlimited
stack(kbytes)        8192
^^^^^^^^^^^^^^^^^^^^^^^^

That limits stack to 8MB. Please change it to 1GB.

Why?
