GE is slow and a faster linear system solver is necessary for the CPU #1

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

Currently Gauss Elimination (GE) is used on the CPU and it is very slow for 
large problems. A faster 3rd party solver needs to be implemented.

A solver from Intel MKL will be a replacement for Gauss Elimination to solve 
large problems.

Intel MKL's direct PARDISO solver can now be used. See revision r674085192340 
for details.

Intel MKl's iterative GMRES solver will also be available in the near future.

Intel MKL's CG solver is also available now for the Poisson solver.
