Posted 12 Jul 2022 by Richie_unstable
Post:
Does the amount of sixtrack tasks still "In progress" ever have any effect on the schedule when a new batch became available ? I think there where a few large batches of sixtrack tasks lately, one after another. It just seems the last few tasks "in progress" would again take ages to finish. Currently for example about 87 tasks still in progress (out of initial +100K per batch ??) and "Users in last 24 hours : 3 ". Barely anything at all happening at this point or extremely slow progress with the remaining anyway. Just wondering ... if that anti-exponential processing speed during final lap in general had any effect on next batch becoming available ?

The project server has indeed a max #tasks per day per app version that are send out to each computer.
This is currently set to 500. Since valid tasks are not counted the real number can be much higher.


I'm not sure if I understood that right but I don't currently see any restriction like 'max 500 per day' slowing down that computer. Sixtrack tasks have been available for about five days now but that computer has run thru almost 13K tasks from this batch already. More than 2K per day. There are no valid tasks yet.

Runtimes of just a few seconds usually mean that the input parameters result in an instable beam hitting the wall very early.
One goal of SixTrack is to sort out those input parameters and continue with those resulting in a stable beam.


Thanks for explaining that. I didn't know that task run time is related to how long something stays safely in the middle of that pipe until understearing at long corners and colliding into wall.

Everything is fine as long as the wingcomputer of the "fast" computer confirms the short runner.


Well, that's what I'm still wondering. After about one day sixtrack history currently looks like this for that faster host:
State: All (3966) · In progress (5) · Validation pending (1303) · Validation inconclusive (2249) · Valid (0) · Invalid (409) · Error (0)

I noticed afterwards that it has run a few sse2 tasks also. So it's not experiencing that problem with avx only... but overwhelming majority of those tasks have been avx anyway.

It looks like practically all 4000 tasks sent to that host run 1-2 sec. Is it normal or statistically even likely that one computer could receive only that kind of tasks ?
It is running them and doing something with them... they haven't errored out. But why all of those tasks can end up invalid ?
That just makes me think something could be wrong, perhaps with that host. On the other hand, it would be a waste if a host could theoretically run 25000 sixtrack tasks in a week without getting a single succesfull validation. Does project server have somekind of special plan for this kind of situations if it continued ?

Hi,

I was browsing things out there. What to think about that:
https://lhcathome.cern.ch/lhcathome/workunit.php?wuid=171155568

Two linux hosts running AVX tasks.

Run times for i5 host have been about dozen seconds but there's one task that run for 1300 sec. That variation looks 'natural' to me. Tasks have validated succesfully.
Run times for i7 host have been 1 or 2 sec (in about thousand tasks I saw one that run for 3 sec). That such a constant speed looks a bit 'unnatural' to me. From 3000 sixtrack tasks that host got then 1500 validation inconclusives and 100 invalids and 0 valids so far. 1500 waiting for validation.

Why is that ? Is something incompatible and boinc doesn't recognize that ?
Would some mechanism need betterment ?
