Confirmed, it is per GPU regardless of vendor.

Still 100 per CPU - no change. For single CPU hosts, at least.

That is what I am getting and my GPUs are the same on each of my computers.
So 300 tasks per computer for me.

I'm at 853 and still climbing. Not sure if I'll make it to 900 before the cache runs dry.

I reenabled Intel GPU work fetch, and got my i5-3210M/GT650M/Intel_Graphics_HD4000 to ask for work, it now has 300 tasks, but they are a mix of CPU and Nvidia tasks, none for the Intel GPU,
so probably a project side scheduler limit change, rather than a scheduler change that introduces limits per vendor.

http://setiathome.berkeley.edu/results.php?hostid=7054027&offset=0&show_names=0&state=0&appid=0

Edit: I've reported this to the boinc_dev list, the changeset was:

http://boinc.berkeley.edu/gitweb/?p=boinc-v2.git;a=commit;h=9889ee8fb64f52e145f889b8fb62c6004f293f0a

scheduler: enforce GPU job limits separately for each GPU type

Previously, if a project specified a limit on GPU jobs in progress,
it would be enforced across GPU types.
This could lead to starvation for hosts with multiple GPU types.
E.g. the limit is 10, and a host has 10 NVIDIA jobs and no AMD jobs.

Fix this by enforcing limits separately for each GPU type.

Yeah something in a bit off. Just noticed my HTPC is up to 300 tasks in progress. Up from 200. Looks like even tho my ATI card is not asking for work it is being granted the limit for both cards.
I am going to try sticking it in a venue that has "Use ATI GPU" disabled to see if it goes back down.
The intended change is not what is occurring.

And with "Use ATI GPU" disabled I'm still getting 300 tasks.

As i am on my i5-3210M/GT650M/Intel_HD_Graphics_4000 with the 'use Intel GPU' setting set to No.

I'm going to enjoy it while it lasts. Now I've got just over half a days worth in my GPU cache, so I can wait a bit longer before panicing the next time things fall over.

That worry is the main reason ] haven't bought a 2nd GPU, even though I sized my MB & power supply for another. Can't see spending money to buy worries.
When this thread opened, I started thinking about it again but Claggy clarified things for me. I don't see any logic in allowing someone with a fairly weak Intel GPU and a GT240 to have 200 GPU tasks but restrict someone with 2 690's to only 100.

I like the way it is now.

Those with 4 gtx690's or with 4 gtx780's like me have now a small chance to survive over weekly maintenance periods.

Edit: Doing now 478 MB and 22 AP. Boincmgr shows 30 MB GPU, 2 MB CPU, 1 AP GPU. (A lot of slots in use, All running concurrently - Please divide AP task time by four and MB time by 8 when comparing to one task at a time.)

Message 1516707 - Posted: 15 May 2014, 19:58:26 UTC

Now I'm a bit down.

Once upon a time there was a Setiland. All people ware treated equally and there was a feeling of harmony around.

One day TheLimit was raised!

Most people noticed but nothing... But the evil was lurking around. An AP hoarder amidst us Seitzens. The universe kept on expanding as time passed by.

But one day - The AP stopped to appear. That was not evident immediately. Everyones cache was filled with a mixture of MB and AP - so nobody realised that until it was too late. No one got no AP anymore. Their caches were run out of AP.

Except for one - there was this evil hoarder. He had set a spell to the magic internet page and made sure that hed'd get no MB. This way he got all the AP in the wolrd!

Oh the groaning and moaning every morning, throughout the day and every evening. No greater evil could have hit us - people said!

Some went to the extent that they switched to another project - some waited their mouths shut.

Time passed by...

And there was this one morning when all remaining GPU coolers whirred so beautifully and all the worlds results loked a bit more shiny. Something must have happened said everyone - no one knew what.

But the a knight in an Arctic Silver IV shining body came and told every person still in the project that the CPU cooler of the hoarder had caught a fire and caused a meltdown of those horrible AP hoarding GPU cores and that the King of the Setiland had issued a permanent order: NO ONE (Tim) WITH A SETTING THAT SAYS AP ONLY AND NOT ALLOW ANY OTHER TYPE OF WORK SHALL HAVE A LIMIT OF 1 TASK A DAY INSTEAD OF 100 PER GPU AND CPU.

The people hoorrared for a total of three days and .....

--

Well - the children are now asleep. Mee too in a an hour or so.

I just looked at at the tasks of another top 10 cruncher and was kind of disappointed. When running AP only I could get 240 000 a day - but I do not want to. I have AP as a preference, but atleast I have this "send work from other projects when available" on.

How would you explain if You had N hunderd AP only? (N is a big number)

I'm not 100% what all that was about. Are you asking how they managed to get lots of AP tasks? With how the servers are currently set machine 6716400 would be allowed to download 800 GPU AP tasks. Which would have been an easy things to do given the recent load of AP generated. I have a machine that keep getting AP tasks to stay capped at 100 CPU AP tasks.

Just how does one download lots of AP? I carry an 8 day cache of WUs and if I have more than 15 AP available at any one time I think I'm in fat city. Clearly, I'm not. I don't want to corner the market, but I'd like to pick up some more AP action. Any tips? Thanks.

It depends on how much time one want's to spend watching the servers and their computers. I had to shut down for the summer but when there was an AP feast I would change the settings to AP only. I would change it back when AP dried up. There are other nefarious ways but I only read about them.

I set a 10 day cache on a couple of slow hosts, never hit the 100 limit and have not run out in over a year. On the real slow one 39 is 10 days.

I'm not interested in nefarious ways, I'm happy to take them as they come, but I read about the large amount of AP traffic that some people seem to get and I never see these numbers.

For me it's luck of the draw. Sometimes my machines get lots of AP, like they did this time, & sometimes they get very few.

AP only. And do not allow other work. :'(
