Hi, I got the "segmentation fault error" when trying to call the PARDISO solver. My input data consists in a matrix of 32014x32014 with about 850000 nonzeros. This data is contained in arrays that are placed in COMMON blocks. I read something about increasing the stacksize in order to solve the problem, but I don't know how to do it. How much stack space do I need to work with such a matrix?, how can I set the stack to that size?.
Neither of these actually remove the limit - rather they use a predefined value from the kernel. If you are using the Intel Fortran compiler, try adding the option -heap-arrays. This will cause temporary array copies to be allocated on the heap rather than the stack.
