How is this possible? How could the CPU run LONGER than the job as a whole. A puzzle. Misplaced coding for data chart/spreadsheet? ID: 3343 · Rating: 0 · rate: / Reply Quote

(I didn't meant SMT or HT) but as far as I know the BH-app does not support it. anyway, did you stopped the tasks while running 'em? it could be, that the reset to the ceckpoint give you a longer spu time as run time...
