I have implemented a fix for the binary download issues some people were having...

Which seems to have fixed the problems I was having on a new host -- I now have a couple of WUs running. Thanks, Jake!

It looked good for a few days, but I've picked up some v166 tasks recently (see examples).

This seems to be happening more and more recently, with multiple outages on some days.

I'd say we're good to go if 643627 doesn't get new work after it reports its latest batch sometime after 1800 UTC.

Well, it's still being sent new work in spite of a 100% error rate. However, it's getting fewer and fewer new tasks so maybe it will be completely shut down in another couple of days.

Good work, Jake. Thanks for chasing that down for us.

I am going to consider this issue resolved for now unless anyone objects...

It definitely looks like we're making progress. I'd say we're good to go if 643627 doesn't get new work after it reports its latest batch sometime after 1800 UTC.

It seems for some reason, that workunit did exactly that, the binary being used is the nbody v168 but the workunit is from the v166 runs, using the v166 parameter files. Before releasing, I took down the older runs...

Maybe I misunderstand, but v166 tasks are still being sent out.

I will do a little more research into configuring the server better throughout the week and run some more tests...

Any update on this, Jake? I've had another result invalidated due to unreliable wingmen. I guess it doesn't make any difference, but all the hosts I've looked appear to be using GPUs that aren't double precision.

One of my PCs is not getting any credit for HOST AVERAGE work done, another seems to be working OK. The OK one also posts USER AVERAGE totals which seem to include activity of BOTH of my Milkyway machines as well as what looks like correct HOST AVERAGE totals.

Just so there's no confusion, what does this have to do with unreliable hosts? For your hosts, I see some user aborts and errors in N-body tasks. However, no massive and continuing computation errors like those pointed out earlier in this thread.

Another otherwise likely valid result of mine invalidated due to unreliable wingmen (628802 and 761112).

Unfortunately, host 643627 went through another cycle this morning of returning 80 errored tasks and getting 80 new tasks...

And it continues...

I just tried turning on some options to reduce workunits sent to hosts that return a significant number of errors. If you see any issues, please let me know...

Unfortunately, host 643627 went through another cycle this morning of returning 80 errored tasks and getting 80 new tasks. Even though the host has a history of returning a lot of errors, does it take time for the server to "learn" that it's unreliable?

On Workunit 1563422500, all three of my wingmen returned computation errors which caused my result to be marked invalid. Each of their respective hosts (629667, 551062, and 740662) is returning errors, almost entirely.

80 workunits is the max any one gpu can get at a time, they do restrict all of us that way. As we return one we can get another, so as that pc returns an invalid workunit if it gets another and trashes it it could be going thru at least 80 per day, alot more if it connects again once it's out of trashed workunits.

Right. But, there seems to be a 24-hour backoff imposed. It's returning all 80 crashed tasks at once, getting 80 new ones, and repeating that cycle 24 hours later.

Post:
Has anyone ever PM'd the owner to inform them their host is producing nothing but invalids?

In my case, I did but got no response.

The host continues to generate nothing but errors. At least it's being limited to 80 tasks/day and is contacting the project only once every 24-hrs. So, it seems like some kind of restriction is being imposed. The user has another host and it's returning valid results.

For me, the N-Body inconclusives are clearing out nicely. It seems now that it's the MilkyWay@Home app that's lagging...

Looks like progress is being made. All of my inconclusives have wingmen now.

Can you please list some of the workunits that are marked as inconclusive and unsent?

For me, the N-Body inconclusives are clearing out nicely. It seems now that it's the MilkyWay@Home app that's lagging. Recent examples:

1560210075
1560204482
1560197795
1560195886
1560188186

And I just noticed I'm building up inconclusives for the MilkyWay@Home app, not just the N-Body, as was the case in the last couple of days.

I've returned to the project after being away for awhile so I'm not sure how much of a problem this has been recently. Regardless, I thought I'd give this thread a bump...

I've only returned a few results so far, but all of my inconclusives for the MilkyWay@Home app (not the N-body) include a wingman whose host (ID 643627) has been returning nothing but errors for at least the last 4 days.

Can't something be done to halt the sending of new work to unreliable hosts?
