It seems that long WUs aren't afterall that much gain for everybody. We have dropped by 1000 WUs in progress in one single day. We may be trying to push the computations too far here. The last thing we want is to scare people out and run away from GPUGRID.

You may have to consider external factors, as well as your own internal choices.

Do you have a medium/long term record of that "WUs in progress" figure? I suspect that you may have been affected by that other big NVidia beast in the BOINC jungle - SETI@home.

They have been effectively out of action since the end of October. You may well have been benefitting from extra resources during that time. SETI has been (slowly and intermittently) getting back up to speed over the last week or so, and as they do so, you will inevitably lose some volunteers (or some share of their machines).

Having said that, I've got IBUCH_*_variantP_long running on all four hosts at the moment - I'll comment on your other questions when they've finished, in 5 - 38 hours from now.

I would suspect another reason is the new GPU app for Primegrid. Fermi cards are the performance leaders. No babysitting required. Credit is high, probably too high IMO. WUs are short. Most important, the project admins listen to the users and are very proactive about solving problems and considering user suggestions.

Well,

It seems that long WUs aren't afterall that much gain for everybody. We have dropped by 1000 WUs in progress in one single day. We may be trying to push the computations too far here. The last thing we want is to scare people out and run away from GPUGRID.

We are going to reconsider the strategy for "fast-track" WUs.

What do you think?

Since I have an older card, an 8800 GT, I would prefer short versus long. At this very moment, my 8800 GT
is crunching a WU that looks like it will take 36 hours of run time, and the WU is not flagged "long." No way I can shut down my PC with this one and still gain the "quick return" credit.
