The Sparse Matrix Solver is currently running in the in-core memory

robustness, it is generally recommended to run in the out-of-core mode
when pivoting is turned on as the amount of memory needed by the

using the DSPOPTION command.

The Sparse Matrix Solver is currently running in the in-core memory
mode and pivoting has been turned on for this problem. For
robustness, it is generally recommended to run in the out-of-core mode
when pivoting is turned on as the amount of memory needed by the
Sparse Matrix Solver cannot be accurately predicted before calling the
solver. If a memory error occurs, please change the memory mode by
using the DSPOPTION command.
