The old 1500 MHz 32-bit Pentium M laptop is faring better on SG than on PPSE.
It was completing 6 PPSE tasks/day and winning none during TdP (it would get one occasionally before), taking around 15,500 seconds to complete a task. There's very little choice what to run now that LLR2 doesn't run on 32-bit XP. It might do better with seive work, but I doubt it has enough RAM.
On SG, it does 7 tasks/day @ 12,365 seconds it's first on 3 (even though it doesn't count for TdP). A few fast systems are doing SG tasks in less than 700 seconds but they have thousands of tasks downloaded. The laptop easily beat a Xeon W-2125 CPU @ 4.00GHz by a margin of over 18 hours. At that rate, if it should be so lucky, it would come out first on an SG prime with many hours to spare. The odds of success are at least measurably greater than zero on this subproject, thanks to these wingmen.
The laptop is propped up on it's side so that the exhaust vents upward out the other side and the normal inflow is unimpeded. This seems to be thermally more efficient than the normal orientation. It's been running like this almost continuously for more than 3 years.
