Development for LHC@home

This new version updates the CVMFS cache. It will reduce the amount of data downloaded during each VM start.

But that is after having to d/l a 1.14GB .vdi

ISP's must love doing that.

It will reduce the amount of data downloaded during each VM start.

The first cmsRun started within 7 minutes up-time.

But that is after having to d/l a 1.14GB .vdi

ISP's must love doing that.

The one that I have is a bit bigger than that:
-rw-r--r-- 1 eesridr users 3008364544 Mar 25 11:38 CMS_2019_03_25.vdi
However, a two-core task that's been running for over 4 hours has only downloaded 151 MiB, compared to about 1 GB for the old version. Swings and roundabouts...

The 1.14GB was the vdi.gz compressed file (1224983110 bytes).

Ah, OK, I didn't realise it was sent compressed -- I'm slightly surprised it compresses so well.

Yes, looks like a small bug in the indexing. finished_0.log is created at startup and is supposed to be overwritten by the log of the first job. Looking at the timings of some job logs, the first log is written to _1, the second to _2 and so on.

Download finished after 12 s if the vdi is already in the local proxy's cache.

First task running successful, third is running now, but second had this error:

First task running successful, third is running now, but second had this error:

That looks like a transient local error -- something went wrong trying to set up the VM, but I don't see enough info to be more precise. Was your machine perhaps near its memory or processing capacity with other tasks?

Ivan,
this third task shows no RDP-Console in Boinc-Manager. Graphic is ok with Firefox.
In this Boinc-manager only one Einstein is running at the same time.
Memory 23 GByte in use, 9 GByte free in Windows.
Was not before the screen as the first task finished and the second died.

CMS_2146187_1553327273.079524_0 this is the second which died.

I know it's no consolation to you, but this is beyond my level of knowledge. In fact I have a few machines I've never even got VirtualBox to run on (in one case I suspect it's the corporate Kaspersky antivirus install which managed to worm its way into my Win7 machine despite my best efforts to avoid it). I just updated my Linux Mint kernel at home, which killed my previous VirtualBox; I've managed to install a copy from a repository, and the extras, and the Guest gubbins, but when I try to look at the VM consoles in boincmgr I get nothing and a message on my screen:
execvp(rdesktop-vrdp, localhost:53594) failed with error 2!
I think error 2 is file_not_found, but how to find which it is is difficult -- strace is way too verbose...

This is a task from the previous version that I was letting it finish while waiting for the new version to d/l and it waited until it was finished and then called it a computer error.
And it wasn't my computer.

So I will abort the other one since I rather not run 18 hours for no reason and dragons and penguins are not allowed where I am.

Ivan,
this can checked from Laurence, if he have time therefore.
It is good, with your help to see CMS now running again, thank you.
My third task crashed at 5 UTC with dragon-Error as Magic wrote:

.

I also have the version 49.00 stopping with Condor ended by dragons now and looking at Ivans 40 core Xenon I see he is also getting many of those Condor ended by dragons

And now the server is telling me 3/27/2019 1:18:16 AM | lhcathome-dev | This computer has finished a daily quota of 1 tasks

So no more work on this one AND the other 2 hosts are still d/ling that new vdi.......so I sure hope in the morning I don't find that it has to be updated to another new version and that I will have to do that all over again.

The server status says Simulation 100 unsent 52 in progress and make_work_app boincai05 Not Running

1:30am .........

Yes, sorry about that. Laurence says: "I have fixed the issue but it will only be picked up by new VMs".
So, any VMs started before 0600 GMT should probably be aborted. Note the jobs seem OK, it's only your BOINC credit that will be affected.
