I made a new BoincTasks thread so that more users will notice it.

It is a feature going back to BoincTasks 1.40.

Either there arn't as many VLAR's around recently or the servers are taking the hint that I don't want them on my cards as I havn't had to abort that many today.

Cheers.

I also run BoincTasks and apparently it caused the problems I reported in this thread. Will watch for new version, thanks.
P.S. Had another suspend last night and almost ran out of gpu work before I saw it this morning.

I obviously spoke to soon as I've just aborted several more of the rotten things. :-(

Thanks Fred, I'll take your advice and not move the GPU VLAR's to the CPU any more. The rescheduler was a very handy tool back in the day!

VLAR's on my GTX660 take 2-3 times longer than normal angle ranges.

This would be fine if we received comesurate credit.

Question - Is the low credit vs runtime due to creditnew? as the increased runtime does not seem to be due to cputime?

Can we expect an increase down the road as more VLAR's on Keplers get validated?

perhaps yes. When slow devices will return more work credit should rise... at least peoples who somwhow understand that "CreditNew" say so...

I'm not convinced he knows how BOINC works, it certainly doesn't work the way he thinks it does, so how he thought he could write a new credit system is beyond me.

As I post on beta, a simple <VlartoGPU>0|1<VlartoGPU> at the client side, could easely solve the problem, allowing we to choose if we want or no crunch VLARs on our GPUs.

Yeah my APR on cuda50's was just taking hold when I got a bunch of VLAR's
now I'm back to crunching cuda42:-(

Any news on this area?

If my memory don´t fail, some time ago, i see a vlar aborting script, does any one still have one or knows where to find?

The video lag on the multiple GPUs when runing 2 or more Vlars is to high, even with changes in the configuration (mbconfig), so i need to find an automatic way to abort them or i will be forced to stop crunching SETI while use the host (loose about 40% of the processing time of the day) because you never know when the Vlars arrive and can´t babysiting on each host to manualy abort them each time they arrive.

To de development people: Please give me a way to easely keep the Vlars away from my Nvidia GPUs! as was working on V6.

I know we have no experts here on the intricacies of creditnew, but

with the knowledge that reassigning gpu tasks to cpu's and vice versa can have a disasterous

affect on the resulting credit awarded, is it

Possible that the schedular sic sic reassigning vlar'S to gpu's has had a

major affect on the credit awarded since V7 was released??

All those long long running cpu jobs running vlars are now running much faster on GPU's.

Or did they start over with v7 applications in figuring out credits from V6 apps?

after all VLAR's are the same application as far as creditnew is concerned??
or is it?

Just a bit of news.
I contacted Eric to see if he could stop sending VLARs to nVidia GPUs.
He answered yes, he is going to try to rewrite the code for the servers tomorrow and hopes to have it in place on Monday or Tuesday.
Hopefully his coding efforts go well.

That will cure my only problem with V7 then, I await with bated breath.

I wouldn't mind running VLARs if they were treated as a different "type" of WU, in the way that AP are different. I'm sure it is not impossible to have BOINC manage this situation better than the all or nothing switch. Its a real PITB to see a task identified as being a VLAR, with an estimated run time of say 15 minutes taking an hour or more and thus skewing the figures used to calculate the run time. Now there's a challenge for you Eric...

I was wondering if the VLAR's were actually been treated as outliers. I don't think this computer has done anything else on the GPU for over a day.

I seem to have a lot of "Consecutive valid tasks" but significantly less "Number of tasks completed" and the APR has not decreased, or if it has not significantly.

This might explain why the credits are not being adjusted as expected under CreditNew.

The present state of play is;

SETI@home v7 (anonymous platform, nvidia GPU)
Number of tasks completed 424
Max tasks per day 670
Number of tasks today 14
Consecutive valid tasks 570
Average processing rate 186.00525336363
Average turnaround time 0.54 days
