Description: EXTRACTAUTOSIZE is the threshold model size in degrees of freedom used to select the Lanczos eigensolver over the subspace eigensolver. EXTRACTAUTOSIZE is only used when EXTRACTMETHOD is set to AUTO. For very large models the PCGLSS Lanczos eigensolver is usually faster than the subspace solver, especially if there is not enough physical memory available for an in-core solution.
