New 1000 event tasks

5 days 22 hours ago
Same here too. Got more than a dozen tasks got cancelled while running for hours (some >50% in progress). Some did get cancel before the tasks ran and I'm fine with that.

In addition, got tasks with validation error but it was only a few minutes of running, so that's not as bad when compare to those already running for hours and then got cancelled.

Events count less easily monitored: eventLoopHeartBeat.txt stays stuck.

3 weeks 5 days ago
Hi!
I've been away for a while. Now I see that the file eventLoopHeartBeat.txt in the [...]/boinc-client/slots/?*/PanDA_Pilot-* directory is no more constantly updated, so it always reports "1 event read so far". It's possible to find multiple updated eventLoopHeartBeat.txt files, one for each worker, in [...]/boinc-client/slots/?*/PanDA_Pilot-*/athenaMP-workers-EVNTtoHITS-sim/worker_?* subdirs. However you have to sum up the number of events to get the total...

I don't think this has been done on purpose, am I wrong?

Anyone using Windows 11 should consider virtualization.

Generally, we all should check our computers to see if they're still delivering anything. Regardless of which operating system is installed. For example, this computer with Linux has already failed almost 2,000 WUs.

User is TRIUMF-LCG2. And if I see it correctly, he has around 70 computers, and I'm afraid they all have the same problem.

Hi, I'm receiving Atlas tasks that are supposed to run on 8 cores, but each task is actually using much less than 1 core.

I am running tests with Windows 11 wsl2 /Docker/Boinc without adjusting anything except a few instructions in windows "enable or disable Windows features", it seems to work with Xtrack tasks but only with those, and it struggles to receive tasks to reach 32 threads.

With everything enabled in Windows 11 except for certain Windows features settings, it runs really fast. Don't you think about converting the software and using Docker?

Months trying to get VirtualBox and BOINC to work on my Windows 11 and it was never possible, then I came across DOCKER AND SURPRISE, following the guide was very easy.

ATLAS tasks not honoring CPU limitations on some PCs

I have seen similar behaviour with a different MultiCore-Project (MIlkyway) and BOINC-Client 8.2.5

If there is a local app_config.xml, the client uses the configured settings from this. If there is no app_config.xml, the client ignores what on the project-preferences is configured and uses the last config it remembers, regardless of the setting on the project-preferences

Seems to be a bug in client since 8.2.4 and higher

Ubuntu 20.04 support?

This is the recommended CVMFS starting point:
https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5594

This option shouldn't be used (remove it, except if you know exactly why you need it):
CVMFS_CLIENT_PROFILE=single

This is recommended (as a private volunteer you should understand it as a MUST):
CVMFS_HTTP_PROXY="auto;DIRECT"
CVMFS_USE_CDN=yes



As for CVMFS_USE_CDN/Cloudflare/openhtc.io

https://openhtc.io/
openhtc.io is hosted by Cloudflare.
You don't need a Cloudflare account to use it.
openhtc.io distributes CVMFS/Frontier content required by ATLAS/CMS/Theory via a worldwide proxy network (hundreds of Squid proxies).
If you don't use the CDN CVMFS/Frontier get their data via "stratum-one-servers" (only few worldwide).
Getting the data from a CDN proxy close to your location instead of getting it from a stratum-one located far away is usually faster.
