I thought I might give the genefer a try - the overall run-time estimate seemed long but managable.

Now, after 48 hours of crunching I am told 6% of the task are done - which would mean I need another month or so to finish it (linearly extrapolated)

As this would be way over the time limit I got (June 2) I wonder whether a) I could extend the deadline somehow or b) might as well abort the task.

You'll get credit as long as your result is valid and the WU hasn't been purged from the database. Purging happens only after the WU has been validated by two (at least) wingmen. And even then, it doesn't happen for something on the order of days to weeks after that (depends on the project, I think). Missing the deadline in and of itself doesn't automatically deny you credit, but it does put you at increased risk, and causes the WU to be sent out to another participant.

Are you running Genefer (CPU or GPU) or Genefer (World Record) (GPU only)? On what sort of hardware? The reason I ask is your progress seems slower than I'd expect. As a point of reference, I have a NVidia GTX570 which can do a World Record unit in about 5 days, and one of the shorter Genefer units in something like 12 hours (IIRC; it's been a while). CPU runtimes for me are in the 5-day-ish range, I think (2600K, h/t off). There are of course a whole slew of reasons why units run faster or slower... just curious about this case.

You're running this on your GT 750M, correct? That's a mobile GPU, and mobile GPUs are much slower than their desktop counterparts. 6% in 48 hours sounds about right for that device.

You have several options:

  • You should almost certainly, on that GPU, run the OpenCL app rather than the CUDA app. It should be significantly faster. The same applies to your GT 650M GPU. Your GTX 580 will do better with the CUDA app.

  • Run the short GFN project instead of the WR (World Record) project. The tasks will only take 3 days or so on that GPU rather than a month, and the deadline is 19 days.

  • Run GFN on one of your faster computers. The GTX 580 is probably more than six times as fast as the GT 750M.



As for what to do with this particular task, that's up to you. As Gary said, it's likely that you'll get credit for it if you decide to let it finish, but if it were me, I'd abort it and start running either the long or short GFN tasks using the OpenCL app. On that GPU (the GT 750M) switching apps should give you a significant boost in speed. That GPU might not be able to make the GFN-WR deadline even with the OpenCL app, but at least it will be closer.

Hi Gary,

Thanks for the clarification.



Are you running Genefer (CPU or GPU) or Genefer (World Record) (GPU only)? On what sort of hardware? The reason I ask is your progress seems slower than I'd expect. As a point of reference, I have a NVidia GTX570 which can do a World Record unit in about 5 days, and one of the shorter Genefer units in something like 12 hours (IIRC; it's been a while). CPU runtimes for me are in the 5-day-ish range, I think (2600K, h/t off). There are of course a whole slew of reasons why units run faster or slower... just curious about this case.

As Michael suspected I run this on the mobile card. I'll give it some more time to see how things develop - the last hour brought a jump of 0.7%.


p.s. Wow just noticed you've got a TON of credit and history and only your 1st message board post. Welcome!

was lucky enough to have access to some nice machines for testing :) and so far everything went fine - this was my first "problem" ...

Hi Michael,


You're running this on your GT 750M, correct?

right


As for what to do with this particular task, that's up to you. As Gary said, it's likely that you'll get credit for it if you decide to let it finish, but if it were me, I'd abort it and start running either the long or short GFN tasks using the OpenCL app. On that GPU (the GT 750M) switching apps should give you a significant boost in speed. That GPU might not be able to make the GFN-WR deadline even with the OpenCL app, but at least it will be closer.

As just mentioned, there was a jump which made me regain hope it won't take as long as estimated. However, if I see it slow down again, I'll probably switch to OpenCL.
