Server Crash November 10
(Message 33297)
Posted 15 Nov 2009 by bobgoblin Post: If you want to see totally poor management, go look around at Cosmology. There are issues which have not been fixed in over a year. Admins continually bungle SQL scripts. The server crash in February/March of this year still has not been completely "fixed", meaning there are newer issues than those that are more than a year old, so they're not even back to where they were before the crash. I crunch for several projects and there are always ups and downs with all of them. Some just vanish with no word as to why. But Cosmo... that's the perfect example of how NOT to run a project. |

GPU app teaser
(Message 32731)
Posted 25 Oct 2009 by bobgoblin Post: There are a lot of computation errors going around nowadays, about half of each batch of 48WUs on my 'general use' PC ends up that way. Almost none on my crunchers. Doesn't seem to be hurting the rac though, probably because they fail as soon as they start and don't waste much time crunching before failing. I figured out my own problem. The issue of MW locking up on the gpu had been going on all along. I had been running multiples, 3 @ the same time. I would notice much later that only 2 or 1 were running, then close Boinc and restart. But I had switched over to running only 1 @ a time, and several weeks later I began having the intermittent problem of MW not processing at all as the 1 unit has locked up and cannot release the next to process. I finally realized the two issues were the same issue and started running 2 units at the same time again. |

Almost none on my crunchers. Doesn't seem to be hurting the rac though, probably because they fail as soon as they start and don't waste much time crunching before failing. I'm seeing several wu's with computation errors too but not in that great number. I noticed some running version .20, and my GPU would lock up every now and then, hd 4850 1g with catalyst 9.9. so I installed version .20b. but now the lock ups are happening more frequently, so I upgraded catalyst to version 9.10 last night. It only ran a few hours and locked up again. It seems that if they fail right away, then the gpu doesn't lock up. But if they fail after they've been crunching for a few seconds or near the end, it locks up the gpu |

There have been a lot of these in recent days. right, boinc doesn't receive the reply back that the wu has been successfully reported. oddly, i have a bunch of wu's stuck in Pending. that's unusual for this project. |

Posted 20 Sep 2009 by bobgoblin Post: ABC recently cut their credit by 75% when they released their new app. They doubled the credit a week or so ago, but it's still not back up to where it was. last time I looked they were trying to figure out how to get it the rest of the way up. Collatz is good, and I used to run 3x+1. But their ATI units freeze up after an hour or so on my i7 w/ 4850. I think my card maybe overheating. plus it's only a 512m, which could be too small for their size wus. But possibly it's because I'm still running 6.6.36? |

Confused..about what GPU support is coming 1st
(Message 24490)
Posted 7 Jun 2009 by bobgoblin Post:
The ATI app only processes CPU WUs on an ATI GPU. Once the Cuda code is released and MW GPU, which is a separate project, begins sending work an ATI app will be made available to process Cuda WUs on an ATI GPU. Afterward, the ATI app that processes CPU WUs will no longer be allowed. |

Posted 9 May 2009 by bobgoblin Post: bob>where can i get one of these scripts? Oh, you mean the thread that was locked for administrative purposes??? Yeah, I finally figured it out using windows task manager. and a few people have PM'd me since. Now my CPU machines have a small but constant flow of work, and my GPU gets units in small batches but allows me to continue running 4 ABC and 4 CPDN wus concurrently with 3 Milkyways, when I get them. my average has jumped up from about 1000 to 25000 a day. still a far cry from the 80k/day I was getting just 1 1/2 months ago. thanks, v |

Posted 9 May 2009 by bobgoblin Post: There is another way to reduce the hammering of the server -- eliminate support for ATI GPU <smile>. That is where the server stress started. I'm not advocating that (even though I have no ATI 38xx or 48xx cards deployed -- not a gamer or photo processor or CAD/CAM guy), but as long as folks are seeking to solve a problem, add that as grist for a potentially flaming discussion. There was some server stress when gpu was opened up, but more so when they increased the min number of wu's on the server that would trigger new wu generation. then the server started sending out "Low" responses all the time and everyone's boinc clients started scheduling way off in the future. what may have been a better solution would be to reset the trigger amount back where it used to be but generate more work at that level. Before travis monkeyed around with those trigger levels, there was something on the order of 80k wu's running at any time. now there are only 30-ish k. |

Posted 5 May 2009 by bobgoblin Post: For a start they are using GPUs in their machines, which get through the wu's very quickly so their machines then ask for more work more often. where can i get one of these scripts? all my machines are dry as a bone and have been for a month. |

Posted 23 Apr 2009 by bobgoblin Post:
greed for work units isn't restricted to gpu machines. and there seems to be plenty of complaints from both sides. my GPU machine is just as dry as my CPU machines. in fact, i've switched it (an i7) over the cpdn and abc pretty much exclusively. and my core 2 duo is doing artificial intellegence when it cannot get any optimized mw. my old 3GHz p4 is relying heavily on poem and enigma when there are no mw units. And my even older 1.8 celeron & 1GHz p3 I just let run dry rather than trying to micromanage them. once the gpu-genie was released, i don't think anyone expected the onslaught of new (gpu) users that knocked mw on it's cyber-butt. and I've deleted the rest of my post as I've just realized I was degenerating into a rant of sorts. |
