2) Message boards : Number crunching : New Computer, Unable To Get GPU WU's (Message 67892)

Thank you very much, Keith! That simple little fix did the trick for me.

I had no idea that OpenCL was dropped from the current nVidia PPA drivers, nor was I aware in turn that Milkyway@home required them. Hopefully this information can possibly help someone else in a similar situation in the future. :)

I used to participate in this project until my old computer system gave up the ghost in January, and was unable to contribute again until building my new current system in September, and I have not been able to get a single Milkyway@home work unit since returning.

I have tried resetting my project on BOINC several times, and I am able to use my nVidia 1060 GTX on Asteroids@home units - joined in lieu of being unable to resume Milkyway@home - with no issues at all. And yet every attempt I make at getting Milkyway@home work yields the same results:

Sun 11 Nov 2018 07:46:56 PM EST | Milkyway@Home | Sending scheduler request: To fetch work.
Sun 11 Nov 2018 07:46:56 PM EST | Milkyway@Home | Requesting new tasks for NVIDIA GPU
Sun 11 Nov 2018 07:46:58 PM EST | Milkyway@Home | Scheduler request completed: got 0 new tasks

I don't know what steps to take to try and solve my problem, as researching previous messageboard threads regarding similar issues seem to be solved with a "wait for it" approach, but seeing as how I've been waiting for more than a month at this point, I think there might be something else preventing me from getting any work units.

Any help with this would be greatly appreciated.
4) Message boards : Number crunching : Questions Regarding Performance of new GTX 760 (Message 62769)
Posted 3 Dec 2014 by XArchAngel
Post:
I am a returning MW@h user that has recently upgraded from an HD 4780 to a GTX 760, and am disappointed to see this new card seeming to be sluggish at completing WU's. I am aware that ATi GPU's are much more efficient than nVidia for these tasks, but when I see references on this messageboard and elsewhere of new ATi cards completing WU's in under a minute, whereas my GTX 760 takes 7 or 8 minutes is perplexing and disappointing.

A single WU will only utilize about 60% of my GPU core, so I have edited my app_config.xml file to enable crunching two WU's at once, but it still take me around 8 minutes to complete a single WU.

I just want to make sure, is this the norm? Are nVidia cards this inefficient at MW@h WU's when compared to ATi? Are there any software tweaks - such as further configuring my app_config.xml file - to coax a bit more performance out of my GPU?
