I had to transfer some 2-3000 VLARs to my GPU since I was clearly not going to make the deadline just using the CPU In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

I see the splitters are all offline at the moment. I also see it didn't take long for the Crickets to ramp down once the supply of tasks ran out. Uploads are still holding their own, though. If anyone is still having upload problems right now, it may be on their end, not Berkeley's. (I also see that my i7 downloaded a bunch of work from Einstein. I didn't count, but the whole first page of 20 on that site is freshly assigned.)

I went through about 40 of my VLAR timeouts and did not find a case where a resend went to an ATI GPU. Another Fred Support SETI@home when you search the Web with GoodSearch or shop online with GoodShop.

All that and with ATI GPUs not alowed to have VLAR any more it a perfect storm. I think maybe it was a quick fix to correct the CUDA issue by disabling VLAR for all GPUs. I was not really keeping track of the issue when it came up so I'm not really sure on that. SETI@home classic workunits: 93,865 CPU time: 863,447 hours |

All that and with ATI GPUs not alowed to have VLAR any more it a perfect storm. I emailed him a whiile ago about this. Never got a reply about it, whats unusual on technical questions. This happened with the fix for cuda getting VLARs. With each crime and every kindness we birth our future. |

My 2500K will take any VLAR's it can get. Oh, it has been getting them. But it'll gladly take more. :D Cheers. |

That combined with the shorties. For me, shorties mean i can do 3-4 times the number of WUs per hour compared to "normal" WUs. Grant Darwin NT |

Like others, I've had a lot of work request timeouts and have received mostly "lost tasks" after I finally cleard my uploads and resumed work fetch. As expected, I've had about 100 lost VLAR's that were timed out by scheduler because the work request included gpu work. I got to looking at some and noticed they were almost all _2, _3, and _4 tasks. Here's an example that suggests that the VLARS are just running around in circles looking for a home tonight: Workunit 1081757151 During one hour, it was timed out for 5 hosts and was assigned and sent to 2 for crunching. That means scheduler handled this workunit for 5 timeouts, 5 lost tasks cancellations, and 2 successful assignments (assuming those two were not also lost first). That's twelve times - is it any wonder that scheduler is not handling all the work requests? This is just part of the current overload, but....
