I run WCG on my work laptop which for the past two or three years has reported around 2400 FP MIPS (Whetstone) and around 4500 Integer MIPS per CPU after running CPU benchmarks. Suddenly last week it started reporting 820 FP MIPS and 1628 Integer MIPS. Now when I look in task manager, nothing is eating up CPU to prevent access to the CPU and I'm pretty sure the benchmarks would take other work into account. Task manager shows that work units are getting unfettered access to the CPU and shows 100% CPU utilisation, nearly all to WCG WUs
----------------------------------------So why have I suddenly lost 2/3 of my computing power? It's not like the CPU gets tired or anything.... Any suggestions on things to check / try would be very much appreciated.

Maybe you've become un-luckypants ;>) WCG does not do it, but any energy management on your computer would, regardless of WCG since lowest priority science apps would not be considered important enough for the computer management to keep the CPU on it's toes.
Suggest you get a program such as CPU-Z to check if your computer is on maximum cycles. Let us know --//-- |

Same thing has happened to me with a certain laptop before. Turned out the heatsink was clogged up with dust, so the CPU throttled back to avoid overheating. Laptop heatsinks are usually quite accessible - remove a panel, undo a couple of screws, lift it out, blow all the crud off, put back together again. Job's a good 'un.

Definite possibility and one I had thought about, I'll take a look on the weekend. |
