8 wus of Riesel Base Short running now for 6 hours on machine #977.


Edit:

After deleting the 8 wus, the machine seems to run fine.

Can you run this WU in standalone? If we can reproduce this I can contact the devs. At the moment all is running fine on my host.

Sorry reb, I don't know how to receive a deleted wu again.
It will be easier for you to see, how the wu runs on another pc.
Furthermore I try to prevent testing on that pc because it's an external (productive) machine.

If this happens again let me know the WU ID or link to.

Did you have the problem also with the older app? Perhaps update to the latest BOINC client.

Edit:
If you have another WU with the same issue send me the stderr.txt content from the slot dir.

No problems with the older app.
Boinc client varies from 7.2.42 (Ubuntu) to 7.6.22 (Win) on my pcs.
I'm not updating pc #3216 at the moment, because I don't want to interrupt a long running Numberfields-wu ( 36 days now) which we were asked to complete.

I'm getting some that run about 30 mins and some which run quickly.

The higher the percentage the slower it seems to progress.

You are running different apps. The timesteps are constant in log.

I'm wondering why the short ones are taking as long as the non-short ones.

With only a 24 deadline if you're getting a lot of short ones that take a lot longer that expected then it's potentially easy to not make the deadline on others.

Not sure what you mean by different apps. It was the short ones that were taking ages

You should not missing the deadline because the server stores the FLOP counts of the WUs and you will only get as many WUs as you can process in time. There is also a difference if you have AVX / AVX2 or nothing.

This seems to be a recurring issue for me on the older computers (i686 and CoreDuo). I frequently have to monitor and cancel tasks which run for far too long. I don't recall seeing this on Core2Duo and up.

Please note that some older CPUs have no AVX which is a big advantage in runtime.

Fair enough. Right now I have three tasks estimated to run for a minute or so, but they have been running for 23 hours. "Estimated app speed 1.09 GFLOP/s, estimated task size 80 GFLOPs". The work units are:

Comp #1
S148_900-950k_wu_4159
S148_850-900k_wu_2020

Comp #2
S148_950k-1M_wu_7209

Edit: These are for riesel long, not short.

Thats normal. If you run a new app the first time the server need some results to calculate the average runtime. You can see it after some WUs.

Aha, then I'll let them run. Thanks :)
