Yes SuperLU should work on this problem but I think that there is some confusion here. When you use more cores the system is not split into small systems. Each processor will get a bunch of rows of the global matrix. If it takes 1 seconds to invert a 1000 x 1000 matrix using one processor, you cannot expect that will takes 1 seconds to solve a 2000 x 2000 matrix using four processors. It will take longer.
