uplinger re High Load Warning, scheduler request deferred
----------------------------------------It's was the Macs wot dunnit!  We have reached out to the members to try and help them configure their environment. But it appears that they are using a deep freeze or reimaging software on the computers once a day. This is forcing the agents to basically detatch and abandon all the results which could be over 2000 at one time. These are then attempted to be sent back out to Mac computers, but the problem with that is we don't have a lot of Mac computers also requesting work. Thus the waterfall effect. 1. Feeder is full of Mac only work units 2. Other computers (Windows, Linux, Android) can't download work and are told to back off. 3. This causes the scheduler to start getting over worked especially when a few slots open. This is basically a traffic jam of sorts for the rest of the grid. 4. When scheduler is over worked, it tells computers to back off due to high load. So as you can see a waterfall effect. The problem is that during a majorit of the day, things are doing well. And making changes doesn't show any difference. This is happening during the 3-4 AM in the morning my time, which is usually when I'm sleeping. Thus I can only make some changes and hope they work over night. I have implemented a new change to the scheduler and feeder to put slots only based on the percentage of usage on the overall grid. This means that if windows uses 80% of the grid, then 80% of the slots should be available to Windows only. Thus in theory preventing Mac from filling up all 2700 slots. |

Evening all.
----------------------------------------Always good to see a new member to the team, welcome aboard threnobulax. Macs eh! Can't think of a decent reason to do such a regular reimage of a computer. I can only see problems with that, and certainly more that it could fix. Remember a site I deal with at work restored a full system backup every night on each computer, of course anything stored (e.g. work related docs or spreadsheets) on that machine then disappeared for the following day. And the works HDD almost had a major failure this morning, Windows kept having huge issues writing to the drive, so much so that the machine was barely usable. Bad blocks ahoy! |

Thats crazy, a re-image only needs to be done if something is wrong with the image on a box or there is new software that needs installed. There is also the strain on the HD, causing more failures.
----------------------------------------Easier to write a script to delete files that are not in the image and that should be run only if they are causing problems.  |
