Ok, I think I have everything back to normal now...I accidentally changed the number loaded to 200000 work units, this was meant to just be changed to 2000. This reflects the number of average work units in a batch so that we can maintain the 200 batches per day for OPNG. Again, I apologize for the confusion this may have caused... Thanks, -Uplinger No worries! The kitties forgive you for sure. They were starting to worry that my GPU had broken because it wasn't doing anything. (I don't think the kitties would mind if you duplicated this mistake once a day....LOL.)  |

Thanks, -Uplinger How long do you think until more batches per day are released? Or larger batches. Whatever gets us to the point of having the GPUs consistently busy. Is the limiting factor the server load? How did the server fare during this mistake? Or is the limiting factor just an effort to keep CPU work available for CPU users? If that’s the case, I have to wonder why you’d intentionally delay the science results just to placate slower devices.

Thanks, -Uplinger Well people here are more worried about not getting any. So, a happy mistake! |

If that’s the case, I have to wonder why you’d intentionally delay the science results just to placate slower devices That's why Keith is the lead tech and you're not.

Since this impromptu stress-test has occurred- and the world didn't end- would it make any sense just to leave the configuration parameter at the higher value, and unleash the grid to do what it does best? Who would complain if project progress surged ahead?

Look at your invalids, and server aborted first.......
----------------------------------------Things did not end well This is not normal: https://www.worldcommunitygrid.org/ms/device/...s.do?workunitId=618783001 And: https://www.worldcommunitygrid.org/ms/device/...s.do?workunitId=618613464 And there's tons more out there.

Good evening,
Our plan is to maintain the pace (which was increased to 2000 work units every 30 minutes) so that we do not over load the pipeline. All of this requires consideration and planning. For example, creating too many results at one time could over load a database, it could cause file upload handler to become overloaded, it could fill up the researchers servers, etc....There are lots of parts that need to be considered on everything. Some of the things we need to consider could cause harm to other projects running here on World Community Grid. As with many of our research projects we start them at a pace that makes sense with us and the researchers. This heavy scheduling did however bring to light an issue with scheduler that I will need to fix going forward. Thanks, -Uplinger |

thanks for the reply. sounds like you'll continue to increase WU availability as your confidence in your process and system stability grows, and that's good to hear.
----------------------------------------you could also likely leave the WU distribution quantity the same (2000/30mins) and just increase the WU size (more jobs per WU, or harder jobs per WU) to increase the work being done without negatively impacting your infrastructure. that's kind of a win-win.
