Is there no Limit per Host?

bcavnaugh is right, there is no per-host limit of tasks in progress here; at least not any below the boinc client-side limit of 1000 tasks-ready-to-start.

While imposing a limit of tasks in progress per host is indeed another way to try lowering the overall amount of tasks in progress, it is not as effective as shortening the deadlines, AFAICS. Users who really want more tasks from a project with such a limit, simply add more hosts.

By the way, SETI@home is an example of per-host limits gone wrong: Their limit is so low that modern hosts fall idle during SETI@home's regular maintenance window each Tuesday (unless users with such hardware work around the per-host limit).

Very True about SETI@home on their Tuesday Maintenance Day

True, but then the last Project also should not have been as well.
This Project was also used in other events and challenges and could not provide Tasks for all the year.

Basically all projects are chosen as possibilities unless there is sporadic work or its still beta testing. FB has been running for over a decade. I'd guess if a project admin requests their project to not be included it could be made so.

On June 21, I wrote:
What are your average task turnaround times?

I can estimate it: https://stats3.free-dc.org/stats.php?page=proj&proj=ast is currently showing about 65 M PPD for the entire project. And http://asteroidsathome.net/boinc/server_status.php shows a limit on tasks in progress of about 320,000.

~65 M PPD / (480 points per task) = ~140,000 tasks validated per day

~320,000 tasks in progress / ~140,000 tasks validated per day = ~2.3 days average completion period of the WUs

Edit:
More interesting than the average would be to know what the distribution of the WU completion times looks like. Then decrease the task deadline to the current 75-percentile of the current WU completion times, for example.

(By WU completion time I mean the time from issuing the first tasks until validation of the two required correct tasks.)

Task deadlines of less than the current 10.5 days should enable Asteroids@home to get more WUs done per day with the same amount of disk space for tasks-in-progress (if other factors, e.g. disk space for whatever post processing you d, are not limiting).

Greetings All

Name another Project that has a weekly outage, not one comes to mind, so you can then say that Seti is not the norm, but an anomaly.

LHC has been using max jobs per core and works well.

My thoughts on the matter, a bit of a turn off to rock up and participate and there is nothing to crunch on.

You win some and you lose some, anyways GRIDCOIN smashing the opposition.

Cheers

Gridcoin aren't smashing anybody. What they do is trying to harvest fake money; nothing else is their concern.

Meanwhile, tasks-in-progress has fallen from 320,000 to 290,000, while tasks-ready-to-send remain at ~0.

I meant in the Formula BOINC leaderboard for this sprint.

The GRIDCOIN discussion is for another day, I dont want to hijack this thread.

Not a fan. Not associated either.

There is a possibility of WUs for your 1080Ti ... there aren't any available at the moment.

Your Thought really comes before the Mining Teams Took Over BOINC for Fake Money.

Still not getting any Tasks.
I wonder if the Real Formula One runs this way as well, kind of like saying you cannot have any Fuel for your Race Car.

To expand on what Woodles wrote, my understanding is that the work scheduler can distribute tasks freely to any of the current application versions, regardless what OS or CPU architecture or GPU architecture. (The latter being limited to cuda55 on Win/x86, Win/amd64, Linux/amd64 currently.) Thus, GPU tasks are scheduled out of the same pool of work as CPU tasks. And hence, GPU tasks are equally scarce as CPU tasks.

So I suggested earlier in this thread that shortening the task turnaround times (e.g. by means of shorter deadlines) would enable this project to get more work done with the same amount of disk space.

Now that I have watched server status for two days, I think I was wrong. It now seems to me that not the tasks in progress are filling up the server, but the completed and validated tasks = finished WUs. I.e. I suppose that the project admin needs to periodically move the end products of the completed work off of the server. And if the admin is late doing so, everything grinds to a halt of course.

Reasoning: Tasks ready to send remain near 0, while tasks in progress decline by 80,000 per day now. Hence, it can't be the tasks in progress which clog the server, it must be the completed WUs.

PS, if this rate holds, tasks in progress will be 0 on Monday.

Not sure what mining really has to do with Formula BOINC Sprint participants causing a shortage of work for a project. Two weeks ago there was a shortage for awhile as well and during the event the credit earned tripled for Latinsquares. Gridcoin does a huge amount of BOINC work but I don't recall that team having as large of spikes as other teams during FB Sprints. Gridcoin users carry on for the most part and the rest of us caused the outage.

Disclosure: I don't agree with the historical reasoning for a crypto currency. Its mostly a waste of electricity. On the other hand w/o it, some people wouldn't be doing good with Curecoin, Foldingcoin and some of the projects Gridcoin whitelists. At least on the FAH side, foldingcoin does not have a team requirement unlike Curecoin and Gridcoin.

As mentioned by xii5ku in the other thread, I don't know if S├ębastien notifies admins judging by the reactions of some of the admins. But if any are concerned over the high load caused by the sprints, my guess the time for opting out is at the beginning of the year. It's like no complaints means its ok to be included I guess.

"aborting the tasks would be like putting them back in a container for someone else to use" But what is the Point as the Sprit would be over.
One way for Teams to Bunker all the Tasks and not let other Teams have any to run the Sprit, so it is like dumping the Fuel on the Ground as posted below.
