It would be far simpler to remove the whole section that does the credit calculation and replace it with a simple look-up table, with Angle-range as the control value, and credit as the return value - having spent a few weeks looking at Angle-Ranges and Run-Times I think there would only need to be four or five values - so simple to implement and so effective..... Wrap a bit of fairly simple error trapping around that and you get a "fair" credit system that awards the user for the task run in much the same way as many other BOINC based projects do.

+2001 Leave the credit system as is just to calculate runtimes (after 11 successful tasks it gets it close for one type of job) and replace with a lookup table as most other projects do for the actual credit, ie roll your own.

But, since it is as broken for everybody else as it is for me, it still allows some comparison between myself and all others here on Seti.


Except for the people who are abandoning all GPU Green Bank work. Saw a dude on the first page of the top computer stat page who, between his 4 computers, has abandoned almost 2000 tasks to keep his precious RAC up. That's getting to the point of absurdity IMHO...

Yeah, a bit crappy. Dunno how someone can feel much pride in that accomplishment. You might out him right here in this thread. The we'll see how proud they are of their RAC.

As usual, the kitties have taken the high road and are dutifully crunching as best they can everything that the server sends.

Meow!


Same here, every one I download gets crunched.

I must admit that with careful use of the suspend button I am re-arranging the order of the crunching so that I am doing either guppie's or regular mb's at any one time.

I am running 2 WU per card and had noticed that a guppie running with a mb slowed the mb down, OTOH the guppie was running faster than when 2 guppies are running, but wether it makes any difference in the long run I do not know.

What I do know is that if I get it right I get no stuttering when I am watching a video. Guppies reserved for work time.

Well actually if you look since the 19th May it is 3,990 tasks.

If top users all start doing that we will start getting 10 "abandons" and the tasks will be lost.

Worrying.

What a scoundrel. Hopefully the randomness of resends will circumvent that scenario.
And hopefully the kitties snag some of them for the save!

Since he is a member of the GPU Users Group perhaps some one with diplomatic skills could PM him and explain to him how is is screwing up SETI.

I'll pass the word. I thought it was this machine's owner but it turns out this is someone else doing the same thing. Shows 824 aborted GUPPIs.

Would be good to get modified quota system.
If tasks aborted en masse it's hostile action against project and quota system should prevent such malice acts.

Nice easy way to sort this behaviour out - treat exit state 203 the same as a computational error. The number of tasks sent to the abuser will then rapidly head downwards until his RAC is hammered into the ground.

Unfortunately, in its current form quota system completely disfunctional for GPU, especially against such cherry picking malice behavior.
Each new completed task will restore quota much more than it will shrink due to computation errors.

...then roll on the day when the pot of non-guppi work runs out and all that is left are guppi WU.

That would probably be a good thing, IMO the targeted VLARs are the most likely to contain what we are looking for.

Yeah I was specifically referring to http://setiathome.berkeley.edu/show_user.php?userid=71946. Guess there are a couple of folks taking advantage of the abort button. Disappointing.

Yeah I've noticed the same thing, I assume the guppie are creating some bottlenecks, I've tried tweaking the -sbs setting and I can't say it's helped much, not sure what other settings might help the higher angle wu's when worked simultaneously with a guppi...

No idea, I stick to simple, easy and non technical solutions, if they work - great, if they don't - I try something else.

The reason that I was playing around was to stop the occasional stuttering when watching certain video formats, If I get faster throughput of WU's its a bonus, but it was not the reason I done it.

Hopefully a better solution will be found and made available in a format that us non technical types can install easily.

I was able to contact Dr. Eric Korpela. He indicated that a solution to allow GUPPI VLAR GPU work units to be refused in the Project Prefs. is being worked on. Please pass it along...

Hope this alleviates any of the misgivings that the project admins. aren't aware of this issue or don't care about it.
