maybe someone can clarify on this.

as far as i can see, the gnfs-lasieve* processes are not counted towards total cpu-time although they consume alot of cpu time?
when i observe a workunit in boinctui current_cpu_time does not increase when the sieve processes run.

oh and what the heck is this?

These tasks ran on a 40-core system:

https://yafu.myfirewall.org/yafu/result.php?resultid=2424269

https://yafu.myfirewall.org/yafu/result.php?resultid=2428966

First Task: CPU time roundabout 3 times the runtime
Second Task: CPU time roundabout 9 times the runtime

But the best: second task cpu time is over 9.5 times as long as first, but the first task gets over 22 times the credit, like WTF?

Another example:

https://yafu.myfirewall.org/yafu/result.php?resultid=2448537

runtime: 100,336.00 sec; cpu time: 546,383.60

running on 40 cores the overall cpu time should be around 30 to 35 times the runtime, which is clearly not the case.

people contribute to this project for free, at least try to credit their contribution correctly

Runtime and cputime is meassured by BOINC client.
Don't know how and why it is wrong.
Maybe child and subchild processes are not considered correctly.

So If I follow the way of thinking , all people participating on this project are wrong, can not use computer !!!
Please admin, reconsider your WU !!!
Look to my post. !!
Today I tryed gain to crunch. Perfekt the same as before.
Impossible to run a other program together with YAFU. I speak about program, not other BOINC.
After a few second opening something else, all freeze.. And CPU do nothing 'except task manager).

I tryed to copy/pasrte on my host the different reports here on forum. Impossible !!
I will help and I will understand. But then send me a private message with a valid mail. I will spent time. But I prefer other project who runs without problem.
Look , please all hystory of WU 2584093 who ran on host 33373.
Today, after 3 restart, it is at 95% at 18:02GMT
Three times I needed to unfreeze host by "forced log off".
I answer from a other host, because if I do it from the running host once again it will freeze.

And not forget YAFU is candidate for SETIBZH / FormulaBoinc.One of the requirement there is to have a stable environments, Not a Beta and also not a "test".

I suggest you correct the problems.

Best regards from the first Belgian team.
Please look my signature also from BOINC.BE !!! We are serious,
