Is it something with my computer or a fault of the WU?

Edith asks:
How could the run time be less than the CPU-time? Multi-CPU-WU?

Someone else had no problems processing that WU.
http://www.gpugrid.net/workunit.php?wuid=2694264

This indicates that it is your machine that caused the issue, not the WU.

As for using more CPU than GPU ... in the first couple of seconds this will always be true as the WU needs *stuff* from the main computer which it has to talk through the CPU to get.

As for the CPU:
It's not using more CPU-time than GPU-time, but more CPU-time than real-time.

As for NATHAN's:
The second one failed: I9R20-NATHAN_FA2-4-100-RND8746_0

This time more time on the clock than used CPU ;)

If it's my computer, that crunches most other GPUgrid stuff flawless, what's it?
It's a Linux (ubuntu 10.04) Intel (C2D9450@3.2GHz) nVidia (GT240) with new drivers (280.13) and 8GB RAM running BOINC 6.10.58.

The other WU type that fails always is GPCR:
74-KASHIF_GPCR_14_ba1-8-100-RND2374_2
Do they have anything in common the others don't have?

Might be a coincidence but your wingmen's tasks validated on the 6.15app (Win only), so perhaps these NATHAN tasks prefer 6.15.

Message 22084 - Posted: 12 Sep 2011 | 23:56:48 UTC - in response to Message 22081.

I had a NATHAN crash on my Linux box but it also crashed on a Win7 system. See here.

This NATHAN crashed on my Linux box, plus another Linux, plus a Win7.

This NATHAN validated on my Linux and I have had other NATHANs validate too so I don't know if we can conclude NATHANs prefer the 6.15 app. Maybe they're just crash prone?

Even on a Windows 7 machine they use 98% GPU so they give card a real hammering and make GUI stutter. I am an hour away from completing one on my 460GT

Credits not very good either :( Just over 16,000 for over 36,000 secs including 50% bonus.

There are goods and bads about Nathan's tasks (like all tasks).
The short tasks finish nice and quick on my systems, and never fail to get the full bonus (unlike other tasks). The long tasks on the other hand don't seem to give the best credit, but they are relatively shorter (and again always finish early enough for the full bonus). I expect extra credit is being given to 'other' tasks that require more CPU time. Nate's tasks don't use much CPU at all (another plus).
So far I don't think I have had any failures, but I can confirm that Nate's tasks are running at 99% on my overclocked (687MHz) GTX470, something I was not expecting! On my Apm GPU temps are 62deg C, about 5deg over other tasks, but so far no lag (another plus).
