Re: Ridiculous low credit claim for longer running tasks
... albeit a decidedly downward trend ...

No wonder the trend is downwards. The slower machines are returning their 1st tasks and all are punished with the default 122 credit claim pulling their evt. higher claiming wingman down too.

Don't have to look up what the wingmen wanted [actually what server computed for them] to see how to get from claimed to granted. The variable runtimes will add havoc to this [the norm], as now I finally did get 3 on the radar boat and heading for just 5 hours with the fraction_exact function active, when the 1 previously received on it did 24+ [don't immediately see how to recognize short/long from the result name].

Anyway, if you look at the earlier linked chart you can easily recognize which projects have reasonable stable runtimes and which are ahum. Credit_New is just incapable to deal with this fairly, with the added WCG attitude adjusters in action [Thought US law prohibited double jeopardy... not so it seems devilish ].

I'm seeing the 122 point penalty for some tasks running only 17.5 hours but not others that are running over 19+ hours. confused

Re: Ridiculous low credit claim for longer running tasks
My third WU has finally been validated.
Again, the wingman had a longer CPU time (22.54 vs 19.67) and claimed 477 credits vs my 122. Of course the averaging gave us an expected 299.

I wonder if the 122-trigger might be the ratio elapsed/CPU. My HST machine is a Tthrottled laptop which runs in average at 60 %.
Unfortunately the WU status report does not allow to see the wingman's elapsed time (as already reported by Rob long ago).

Re: Ridiculous low credit claim for longer running tasks
Don't know how to achieve this, but the benchmark is based on 100%, so you might want to mod the two values, so the server is not being misinformed about the device performance. I've set skip-benchmark in cc_config to prevent re-benchmarking.

Re: Ridiculous low credit claim for longer running tasks
pwcr,

I believe your issue is related to the fact that you are running 64 HSTB WUs at the same time. Here read this link https://secure.worldcommunitygrid.org/forums/...ead,38956_offset,0#517069

It is the cause of you having only 25hrs of CPU time in 40 hrs of elapse time. And if you were able to keep it under 39, it would of been good. (Well based on my experience anyways)

Re: Ridiculous low credit claim for longer running tasks
anhhai, don't know how pcwr squeezes 64 threads into the 18.4Gfl per his signature, but everything is possible these days... a second account ;?

The 122 has a different root cause, certainly have trouble comprehending how the Elapsed is getting into the equation when the points are CPU time based, no matter how inefficient it gets.

Re: Ridiculous low credit claim for longer running tasks
My desktop does these WUs in 24hrs, but they mainly go to Pending Ver.
The BOINC manager allocates 6 hrs of cache time.
I have only had 1 WU so far for this project go Valid.
