1) Message boards : Number crunching : ATLAS/CMS Tasks all dying like flies LHC/LHC-dev both (Message 39596)

Well, I don't know. I knew about (but had forgotten about) the BIOS; That's fixed.

I didn't know about hyper-v but that wasn't enabled anyway... I'm a LOOOONG way from being competent in Windows 10.

I don't know about any other errors in my setup - I simply don't know what to look for. It's likely a Win 10 issue since my Win 7 machine seems to be working okay.

Purely as a philosophical observation, I tend to avoid projects that need a great deal of detailed tinkering with the operating system to be productive. I've already changed the profile for my Win 10 machine to not accept ATLAS or CMS tasks until this gets sorted out just as I stopped accepting VM tasks from cosmology@home and dropped climatepredictio@home all together. If that makes my equipment less useful, so be it. There are millions of other folks out there in the BOINC universe to choose from.

And before I forget my manners and get a pop on the head from my Mom, thank you for your help.

Hyper-V was not enabled on this machine.

The snapshot showing was taken before I fixed the BIOS.

Even since then, everything has been dying.

All my tasks for ATLAS and CMS are dropping like flies on both LHC and LHC-dev on just one machine.

The machine is Windows 10, BOINC 7.14.2 and VM 6.0.10.

I posted this to the LHC-dev message board and was politely reminded to make sure VT-x was turned on, which it wasn't and which i took care of. According to Task Manager, Virtualization is now enabled.

Obviously, the fault lies in my machine, Dear Horatio, but I'm darned if I know what. I read the log files, but don't understand a good deal of what I'm reading.

Suggestions would be most welcome.

It would be best, I suppose, if I were to stop getting LHC tasks until I can get this fixed.

By the way, everything is running normally on my Win 7 machine which has the same BOINC and VM versions.

Thanks for the information. It works.

I have one that as I write this has been downloading for over 12 hours. At this rate, it won't have finished downloading before the completion deadline. Haven't seen this before.
7) Message boards : Number crunching : Postponed: VM job unmanageble, restarting later ????? (Message 35527)
Posted 15 Jun 2018 by Thund3rb1rd
Why do you suppose the VM job became unmanageable? When is "...later".

Is there anything I can do about any of this?

These VM jobs are more of a pain than anything else in the projects I participate. Unstable, locks up my computers forcing a hard reboot. Hope it's worth it to the three projects that use it because it sure isn't worth the trouble from my side of the fence.
8) Message boards : Number crunching : How can I change the number of CPU used by LHC (Message 35520)
Posted 14 Jun 2018 by Thund3rb1rd
First - not to forget my manners - many thanks to those of you who took a moment to give me a hand. I genuinely appreciate your help.

I cut-and-pasted the app_config file provide by computezrmle into notepad.exe and created a file I named app_config.xml in the lhcathome.cern.ch_lhcathome directory.

I then returned to BOINC Manager, selected the lhc@home project, and invoked 'Read config files' from the BOINC Manager Options menu.

I immediately received this error message in the Notices tab:
LHC@home: Notice from BOINC
Missing <app_config> in app_config.xml

The <app_config> phrase shows quite clearly as the very first line in the app_config file I created. So - what did I do wrong?

Posted 13 Jun 2018 by Thund3rb1rd
Is there a way to change the number of CPU used by LHC after the job has already been downloaded but before the job starts running? I've had nothing but trouble getting projects that use VM to play nicely together and have decided to download one job at a time for one project at a time and strictly limit the resources used.

So, is it okay to remove vLHC@home from our BOINC clients now or not?

Congratulations to you all on the discovery of the pentaquark! Together with the confirmation of the Higgs boson, the scientists and staff at CERN have advanced human knowledge tremendously.

Geez, folks. Get off Eric's back. It isn't like he sits up all night with a hammer and chisel making tiny rocks out of big ones. I remember not too many years ago before the LHC came on-line when there were no work units at all for many months at a stretch. WU will come when they come. Surely you all are working on other projects to pass the time.
13) Message boards : Number crunching : CPU second differences (Message 27295)
Posted 6 Apr 2015 by Thund3rb1rd
For want of anything better to do, I was just rummaging around in my task list and noticed something that could be chalked up to idle curiosity. Why is it that some tasks need more than 32,000 CPU seconds to run to completion and validate, while others fly by in 300 or 400? Same computer, commensurate number of wall seconds, pretty much same everything. All of them are accepted as "Completed and Validate".

Just curious.

15) Message boards : Number crunching : Very short Intel computation vs. normal AMD (Message 19612)
Posted 13 May 2008 by Thund3rb1rd

anyone seen this before:

My AMD Quad core computed the WU in a "normal" amount of time whereas the Intel based systems ran very short successfull outcomes.

Actually, yes. I have.

Several years ago, when BOINC was still a gleam in someone's eye and SETI@home was the only game in town, I had two PC's. One processor was a 486-66 Intel and the other had an AMD Pentium-class processor. The Intel-based machine would routinely process as many as three SETI@home work units to every one the AMD chip could process. I ran both machines for a couple of years before my dissatisfaction over other things finally prompted me to mothball the AMD machine. To this day, I won't even consider an AMD processor-based machine.

Memory doesn't serve me well enough to be able to quote exact clock speeds and whatnot, but I do remember that I came to the same conclusion as others on this thread... that the mathmatic units on the two supposedly-comparable chips were wildly out-of-sync, with the Intel chip being the better of the two, by far.
