  The Sparse Matrix Solver is currently running in the in-core memory
  mode. This memory mode uses the most amount of memory in order to
  avoid using the hard drive as much as possible, which most often
  results in the fastest solution time. This mode is recommended if
  enough physical memory is present to accommodate all of the solver
  data.

  I see that you have
  GPU ACCELERATOR OPTION REQUESTED
  1 GPU ACCELERATOR DEVICES REQUESTED
  Does the model run when you do not use GPU?
  What name/model GPU do you have installed?
