So I installed a decent gpu in a not so hot box. The GPU is a PNY GT 430 installed in a Celeron D 356 Vista box. Installed Boinc 6.10.60 and got one CUDA-fermi task. GPU started crunching, and right off the bat I thought something was fishy. Both of the "To completion" timers were running forward -- ie, getting bigger. Also, the CUDA GPU task was showing a very high CPU usage, like 0.52 CPUs + 1.00 NVIDIA GPUs. I don't see CPU numbers this big on my other boinc computers. Like I've got a Pentium E2220 with a lousy 8400 GS GPU and it says 0.09 CPU + 1.00 NVIDIA GPU. So I was surprised to see such a high CPU demand on the low-end box.

I watched the elapsed time & to completion time of the CUDA task and realized that as soon as the

% Progress * "To completion" = "Elapsed time"

the "To completion" timer would start counting down. Sure enough that's what happened. That's for the CUDA task timer. The CPU task was still getting bigger because the CPU task wasn't getting as much CPU. That all made sense.

So then, all of a sudden, the task was finished. I looked at the messages and saw:

Sat 23 Jul 2011 10:36:24 PM EDT SETI@home Aborting task 09mr11ag.20908.17409.16.10.203_1: exceeded elapsed time limit 8658.846851

Just when everything seemed to be going gangbusters, the task went belly up. OK, so then my box begged for some more GPU taks and got them. It's crunching one right now, but I can see the exact same thing is gonna happen. The counter is running in the wrong direction and it's expected completion time won't be met. Mark my words.

So my question... what to do?

thanks

k thanks, will repost at seti q&a.
