2nd GPU issue

Posted 10 Nov 2017 by UBT - Mikeejones Post: Even when running the actual DNet client, 2 GPUs won't "share work" - they are always working on different keyblocks. Hi That would assume that there would be 2 Work Units (1 for each GPU) running at the same time, this is not the case. Each Work Unit is using 2 GPUs at the same time. I assume that they totalled the time for the 2 GPUs to complete but even if you double the time taken it nearly works but doesn't quite. If they did then it would explain everything. Mike |

Posted 7 Nov 2017 by UBT - Mikeejones Post: Hi Right sorted it! Tasks ARE taking just 17 minutes. Take a look at this WU https://moowrap.net/result.php?resultid=63919674 CPU and run time is 31 mins 38 seconds, but if you look at the start and finish times (8:57 to 9:14) it's 17 mins. I was watching the WU in the manager and couldn't understand why it was at 90% at around 10 mins. So Moo seems to have a error at their side! Mike |

Posted 6 Nov 2017 by UBT - Mikeejones Post: Hi I've running a Ryzen 7 m/board with 2 X GTX1060's - both 3GB versions, one an ASUS, the other Zotac. Up to last week I had just the 1 1060 and WUs were taking around 2000 seconds which was fine. I added the 2nd 1060 at the weekend expecting either to have 2 WUs running at the same time or 1 WU with the workload shared between the 2 cards. As you'll all ready know, the second option works here. However, I got a problem. The first WU unit completes in around 900 seconds, but every one after that takes around 2000 seconds. This has happened twice now - it's as if the cards are doing the same work twice rather than sharing. Any ideas on how to get them to play nicely? Mike |
