Hello, I also experience a similar problem with the MUMPS solver, when I run it on a cluster. After several hours of running the code does not produce any results, although the command top shows that the program occupies 100% of the CPU.
The difference here, however, is that the same program runs fine on my PC. The differences between my PC and the cluster are: 1) 32bit vs 64-bit(cluster) 2) intel compiler vs portland compiler(cluster) Any thoughts on what might cause this?
