IF you are running netscape, you might quit, or run it with the -install switch. I had fun placing a breakboint at line 54 of my program by moving the cursor to line 54, and clicking with the left mouse button. Then I hit the run button, and then the print button which allows me to view variables. It is particularly interesting to see the variable v in surface mode which is in the options menu in the v window. I had some problems with the color map however.
Timing is tricky on xolas.
Try your best. You might also try some automatic parallelization switches. Do not time anything compiled with the -g option. Pick whichever code you prefer. This may still be done with two colors.
