Hi Jake and/or Tom

I'm a little hesitant to again post this past problem showing up again:

There are big time spans between "last WU completeted" and the "fetch new Tasks" request, which then loads down a big amount of 0 (zero) tasks.

We have tried a lot, have read this thread and others, but don't understand what we are doing "wrong".
Or what we need to adjust.

Would like to point out, that on other projects we don't have this "problem".

Thanks and have a nice day!

I can confirm that.

My Radeon VII needs about 40 minutes for 200 tasks and then has to wait 6-10 minutes idle for new tasks. Strange.

Yes, for some reason new work is assigned ONLY when the current queue is completely empty - all tasks must be completed AND reported. After that, server will assign new work upon next contact, but for a few minutes the client is idle. I have a backup BOINC project which kicks in during that period, but would prefer to crunch only Milkyway (if the queue was maintained).

Perhaps it's necessary from a scientific standpoint i.e. new tasks are created according to results from previous tasks? Obviously, if that's the case, all previous tasks must be sorted out first.

Nope it's not that as there are currently 10976 tasks in the queue ready to send out.

I am seeing the same thing....it looks like they are sending out wu's in batches that use some kind of 'master file' and until you finish all those tasks you don't get any new wu's, then you get a new 'master file' and a batch of wu's to go with it.

Hey Everyone,

This is a known issue, but I have not been able to find a solution to the problem. It's probably an obscure configuration issue or something, but unfortunately they are very hard to track down. Maybe I'll try a post on the BOINC official forums and see if this is a know issue with a specific configuration.

Best,

Jake
