I tried the help and searching here so forgive me if this has been covered.
Why does the world community grid client have to switch between two tasks? I've had too many cases where 2 projects are around 70%-90% each and I ran out of time to finish the tasks. I'd like to be able to take on JUST ONE task at a time, not two. I've seen the "no more tasks" thread, so do I have to always cancel one task and enable the option to do one at a time? Why can't "one task" be an option? (If it is, please enlighten me. :D) Thank you. |

Hi and welcome to forums!
----------------------------------------Go to preferences and look for the "switch between applications between every XX minutes "(default i 60 minutes) Change that numer to 9000 or something like that.Hope I helped  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

(If it is, please enlighten me. :D) Thank you. Do we understand correctly that it a WCG science task and a non-WCG science task? If a client is not able to finish a 2 tasks of 2 different grids in time [presuming you have a 1 CPU computer that can only run 1 at the time, it may be that your cache setting is too high. Set that low, so the client wont be inclined to queue many jobs. Eventually though the client makes a choice and determines there is a deadline issue. Than it will switch to earliest deadline first operation i.e. stops switching automatically. That what Falconet proposes, not to switch unless a job has had 9000 minutes, like a week works too, until the client again finds there's deadline issue and goes for the shortest or the earliest due. At any rate, there should be no need for you to hand manage jobs.

PS, you don't mention the client version you use, but the coming 6.10 client will be better at handling deadline issues, but already if processing due that in High Priority on all CPU cores, work fetch should stop. I dislike that there is a longer period until a project is in deep debt, the client always tries to have a task in the buffer for each active project... and yes that seems to necessitate manual stopping of work fetch for a project at times particularly if deadlines and run-times are quite different.

Depending on your Operating System; there are some programs out there that you might be able to set up a rule so all WU's can only be dispatched on a single core...
Short of this... with what's available at the moment with the clients, I see no other real means to accomplish what you are requesting. You'll have to look around for some of these programs that will set a preference or affinity to a specific CPU for the program... and I'm not even sure it will work... but you might give it a try. hope this helps a bit. |
