This is the step where the Krylov solver and the preconditioners are specified. We select the following:
To continue, proceed to Step 3 (Compute Data) using the button at the bottom of the page. Note that if you don't enable any preconditioners, Step 3 will be an empty box. } else if ($Mode == "intermediate") { ?>
In this step, you should specify what linear solution techniques you want to analyze.
You also have to specify how to evaluate the solution phase. The evaluation parameter, called phi, is defined as a linear combination of CPU time, iterations and estimated condition number. The weights are defined in the "Performance Evaluation" section of this page.
To continue, proceed to Step 3 (Compute Data) using the button at the
bottom of the page. Note that if you don't specify any preconditioners, Step 3 will be an empty box.
