We can make a drive for you to get a new PC? I normally migrate my BOINC files so it keeps the same PC ID even though the hardware changed.

I can only assume that windows is more strict with applying the times from certs? Although I find that hard to believe.

I can imagine at 00:00 the Linux host will also fail over?

I guess that OK for some techy people, but not for average person.

You can do what I did based on the discussion at the main boinc website.

but the web link is http so by definition it wouldn't be secure :)

if you link to https then it's all good.

There is an expired cert that walli reports so it so a new build of BOINC needs to be made with updated certs.

I made my own updated cert and it's working fine now it would appear.

OK, that doesn't make any sense then, maybe the certificate was expired early due to some security problem? I don't think there is much we can do on the client side though?

I assume then it's the server side certificate that expired for these projects. Since all of our client side certs are valid til 2028

Posted 22 Apr 2020 by Toby Broom
Post:
Yes, I run say 50 tasks. In assume in theory yes but seems like for LHC, more cores is better, clock speed doesn't see so important.

I guess you can compare my systems "Carbon" & "Nitrogen" they are both 56 cores but the 8173 is single proc and the 2648L is dual, I'm not running any LHC at the moment though.

You can compare them with this webapp.
11) Message boards : ATLAS application : typical length of time an ATLAS task takes? (Message 42232)
Posted 18 Apr 2020 by Toby Broom
Post:
The ATLAS tasks are typically much shorter than theory, like 4-8hrs vs 12+

You can limit the tasks to use less than 4 CPU's but they will always take about the same time, since the virtual box is a wrapper for the real work they all do a number of smaller jobs inside the VM so the wrapper run time is somewhat arbitrary
12) Message boards : ATLAS application : set ATLAS "# of cpus/jobs" in app_config.xml? (Message 42231)
Posted 18 Apr 2020 by Toby Broom
Post:
Something like this will work:

<app_version> 
<app_name>ATLAS</app_name> 
<plan_class>vbox64_mt_mcore_atlas</plan_class> 
<avg_ncpus>1.0</avg_ncpus> 
<cmdline>--memory_size_mb 4000</cmdline> 
</app_version>


You can do on a per computer basis with this, if you only have 1 PC then it doesn't make much difference I think

If it never ran then it didn't waste any time on your computer.

It wasted some bandwidth

I have 0.5/0.01 day buffer for LHC seems fine for me as it very rare that I have no internet connection.

It can take a while for the BOINC work buffer to get its self sorted out, so it will get less crazy over time.

Looking at the workunit seems like someone else returned a successful result so yours was cancelled, did it actually run though?

As the others said maybe you have a big work buffer, it should go down over time once it work out the task rate properly
20) Message boards : Number crunching : Project balance (Message 41439)
Posted 31 Jan 2020 by Toby Broom
Post:
I found out what was blocking it, I had set Max # CPUs to 1, so that ATLAS would use a single core, I set to unlimited and now it gets more Theory and ATLAS.

I'll see if this now blocks CMS tasks.

I used the app_config to limit the number of CPU's to 1 locally, I assume now the working set will be for 8 core task so it blocks many tasks if you have limited RAM.
