I have three hosts running asteroids@home for CPU tasks only. Most of time when they fetch work, they get 0 new tasks. Occasionally, it would get a few or few dozen. This leads to an interesting behavior that the hosts already running asteroid@ tasks would consistently get more work as it fetches very frequently when it reports finished tasks. While the hosts without work initially will almost never get any work because it would fetch asteroid@home once, see no task available and back off for hours while fetching from other projects.

Is this intentional rate limiting, or perhaps all the millions of unsent tasks are for GPU while the server is barely keeping up with CPU task generation?

Nothing nefarious going on here, just a quirk of the scheduler.

Circumvent this issue simply by running an update script every 5-15 minute, your choice.

Sure I can do that. Was it always like this? I thought this project is somewhat sporadic, but now I wonder if I simply didn't pay enough attention before. Looking back in history, I can see the project had unsent work on most days, certainly more than the days I've seen my hosts crunching it.

Yes it looks like something is not going well with the server. Last time I received any work was 4 days ago for the one Android phone that's on the "compatible" type list here.

I'm thinking it's an influx of WCG refugees (like me). World Community Grid is down for the count until January 3 due to a massive data center cooling overhaul and no resources to temporarily move it to another cloud.

I wonder if we will see any sort of Christmas bump as well, from people attaching shiny new PCs to the project?

Once WCG is back up, my x86 hosts will be going back, but the Raspberry Pi fleet will stay since WCG hasn't had any work for Pis in a long time.

Merry Christmas!

There are more than 2.35 million tasks Asteroids tasks ready to send. But I haven't received any for days.

My event log says "Not requesting tasks don't need (CPU; AMD/API;)"

Why is that?

With BOINC, you only get what you ask for. you didnt ask for any work, so you get sent no work.

the reason BOINC would say "not requesting tasks" could be a few things, but most likely you have more than enough work from another project to satisfy your current work cache and resource share settings.
