Message 37073 - Posted: 22 Oct 2018, 1:02:50 UTC

I have re-enabled ATLAS as a project on LHC to run some of these WU's and every one so far as failed. When I looked at one of the WU's I noticed that it had been assigned to three different systems and failed on all three ?

wuid=102285314

Does a bad batch of WU's ever get generated ?

Thanks

I've never seen a bad batch of ATLAS tasks and I crunch quite a few of them. Check out my hosts and see that ATLAS tasks are doing just fine here. Drill down through the work units I've received and note that a great many of the tasks I've received failed on 1 or more hosts before I received it and completed it successfully. So what you are seeing is nothing new.

Check out the hosts that failed your task and note that none of them have ever returned a success. They are all misconfigured. One of them doesn't even have VT-x enabled. Look around and you will find numerous hosts that are misconfigured and failing every VirtualBox task they receive.

On the other hand, it could be that the ATLAS tasks in my cache are the tail end of a good batch and that as soon as I finish those I will start getting tasks from the bad batch and that they will all fail. But I doubt it. BTW, you might notice that I run the ATLAS native app but it makes no difference... the native app gets exactly the same tasks as the VBox app.

So my guess is there is something wrong on your host rather than in the tasks. Someone more familiar with the error codes in your task's logs will be along soon and they'll maybe be able to pinpoint the problem for you but until then you might want to work through Yeti's Checklist Version 3.

I have had every Atlas job fail over the past three weeks, no matter what machine I run them on. All of my systems are Windows 10, VirtualBox 5.1.30. Msg Too many total results. Task id 207844096.

Your taskID 207844096 was a 4 core task on an 8 GB RAM machine... bad idea.

The VirtualBox tasks are EXTREMELY fussy. You can't just install VirtualBox and let 'em rip. You need to line up about a dozen ducks in a nice straight row and keep them that way or VBox tasks will fail. Theory tasks are a little less demanding but ATLAS and LHCb are an absolute b**ch. The only reason your LHCb tasks are verifying is because LHCb is broken in a way that prevents LHCb tasks from revving up to full speed. If they did get to full revs they would likely be failing too if run on 4 cores on 8 GB RAM. So.... bump it down to just 1 single core ATLAS task running at a time, no Theory, no LHCb, just ATLAS. If that doesn't work then that means you need to reconfigure a bunch of other stuff too as per Yeti's checklist but worry about those bridges if and when you get to them.

If you want to run Theory and ATLAS simultaneously then you ABSOLUTELY MUST set things up to limit the number of tasks that run simultaneously. You can sort of configure that in your web prefs but it doesn't work well. The best way is to use an app_config.xml file.

LHCb? Disable it. It's fubar.

I've lowered the CPU limit to 1 but that does not seem to fix anything.

On my other machine, I have 4 cores but that machine does not select any LHC project work. It is a 16gb machine with 1tb of disk and 4 cores Lenovo 7072-CTO, Windows 10 Pro. I have reset the project but not work is selected.

Are you using the website prefs to adjust the limit? If so then tasks downloaded prior to lowering the CPU limit will run with the old CPU limit. Looking at your list of tasks for that host it appears that you still have tasks in your cache that are tagged to run as 4 core tasks. The only way to change CPU limit after tasks are downloaded is via an app_config.xml. You can abort those tasks because they're gonna fail anyway. New tasks will then be tagged as 1 core unless you have an app_config.xml that specifies otherwise. Remember... even if they run single core they might still fail for other reasons but at least then you will know the failure isn't due to too many cores and then you can work on getting the next duck lined up by examining the stderr output for clues as to what you need to adjust next. Yes, it's a complicated process but it's the only way. One duck at a time. Eventually you'll get all the ducks in a row and then the tasks will succeed.

So a question for you... are you using an app_config.xml or are you setting CPU limit via the website prefs? Either way is fine but there are pitfalls to each method.

16 GB gives you more leeway.

If you're not getting any work then it's most likely due to one of the following reasons:

1) You are running other projects on that host and the scheduler thinks LHC tasks have received more than their share so it's fetching work for other projects until they catch up.

2) The Lenovo is associated with a different venue (default, home, school, work) than your other host (the one that does get work) and the VBox tasks are disabled for that venue.

So... determine which venue you have associated with the Lenovo and then see if the VBox apps are enabled for that venue. Caution: If this is the case then don't fix it the easy way by associating the Lenovo with the same venue as the other host. It will be easier to set things up if the 2 hosts are associated with different venues.

If it's neither of the above reasons then we'll look at other possible reasons but let's work on those 2 for now.

Message 37120 - Posted: 29 Oct 2018, 1:46:55 UTC - in response to Message 37115.  

My LHC preferences is set to home on the Lenovo 7072-CTO processor. I have 3 other computers that is set to select LHC projects. I have gotten other task to run on VBox but not any LHC task. How can I determine if Vbox apps are disabled. The Cosmology task seem to work ok.

Thanks

Find your name on the right side of this page, just below the LHC@home banner. Click your name, it takes you to one of your preferences pages. Click on the LHC@home preferences link. Then you should see Primary (default) preferences near the top with some check boxes. In the section below that you should see either a link that says something like "click to add a home venue" or, if you already clicked it at some earlier date you will see a section for "home" similar to the section for "Primary (default) preferences". Select which tasks you want for the Lenovo there. Keep it simple for now. Click "Edit preferences" and check only
    Use CPU
    Theory application


Then set "Max # of jobs for this project" to 3 and "Max # of CPUs for this project" to 1. That will allow 3 X 1 core Theory tasks to run simultaneously. That leaves 1 core free to help keep the computer responsive. If it remains responsive then you might try 4 CPUs but it's not recommended. Keep it simple for now... start out with 3.

Double check everything then click "Update preferences".

Hi Bill. I did everything that was suggested and still the Lenovo 7072-cto does not select anything. The id for this machine is System-F. Do you have any other suggestions?

Thanks

Bill? As in Bronco Billy? I am honored :)

If that doesn't help then it could be that BOINC cannot see VirtualBox. If BOINC cannot see VirtualBox then it won't request tasks that need VirtualBox. Let's have a look at the Event Log...
1) restart BOINC client
2) click Tools -> Event Log
3) copy 'n paste the first 40 lines of the Event Log here

I don't see any reason for not receiving tasks. It's requesting tasks but not receiving :-(
It won't fix the problem but I recommend changing
<vm_max_used_pct>75.000000</vm_max_used_pct>
to
<vm_max_used_pct>100.000000</vm_max_used_pct>
to reduce chance of "missing heartbeat" error.

If the machine is too sluggish for you to use then reduce the number of CPUs allowed with
<max_ncpus_pct>99.000000</max_ncpus_pct>
instead of throttling the VM
