I'm trying to run an FEM code of mine. The code works well until a certain number of input element (10,000). However, when I try to run the code with 11,000 elements this error appears:
forrtl: severe (41): insufficient virtual memory
Although my code is still very unoptimized since I use a regular solver (DGETRS) instead of sparse solvers, the cluster still has 4 GB of free memory when I run the code with 10,000 elements.
Is there any trick that I'm missing?
