1) Message boards : Number crunching : sixtrack back on track (Message 24330)

Post:
looks like the project has more or less stabilized over the last two days or so. looks like several people may still be having some problems but overall things are looking good from what i can see. ive been getting steady work and all the wu seem to be running fine. in the past two days, i think ive only had one computation error, no download errors or invalid tasks. the few computers i have running lhc have lhc work caches filled properly so all seems to be in order.

as such, i hope those individuals that are still having problems here and there are able to get everything sorted. hopefully most others are stable now too.

just wanted to say thanks to all the folks at lhc for the great work getting the project back on track. its nice to be getting steady work from this project again.

thanks again.

If some users are still experiencing problems then please post the main error messages. The filesystem full issue has been resolved and so has the write permissions. Any details would be helpful

this machine has pending tasks that are of the 1-2 second variety (about 84 of them).

heres an example of the message from one of them (task 3965742):

im pretty sure some of these tasks occured prior to the disk full problem but some of them are also from a few minutes ago which makes them after the point you mention this issue was corrected.

i do not know what other information you would like regarding this but ill provide any further information you may find helpful, just let me know.

i got the same issues today on several other boxes as well. just posting the results from one machine.

thanks.

rob

EDIT:

currently, my main machines do not have any lhc work, their caches were depleted and when they request more work, the server does not send any tasks. this occurred on machines with no cpu work at the time as they are set up to only crunch lhc so i know its not a full work cache issue. these machines are set up with a 2.0/0.1 work cache.

Also ran in to this. Made a forum post for it already:

http://lhcathomeclassic.cern.ch/sixtrack/forum_thread.php?id=3460

Maybe has to do something with the servers being down.

right. i was wondering about this issue after the servers came back up. no matter though, it all seems to be working well now.

thanks.

More news soonest. Eric.

thanks for the explanation on the executables. will wait to hear more before i attempt lhc on those machines again.

if theres any other information you would like to know about these machines to help diagnose any problems, please let me know.

thanks for the update.

Post:
Using 7.0.28, under Projects-Properties I see a -0.00 scheduling priority for this project. My other two running BOINC projects have non-zero scheduling priorities. So perhaps that is a source of the problem although it is a mystery why some people are fortunate enough to receive work units while others are not.

i have this host thats running boinc 7.0.25.

it has many projects attached but only three set to get new work for these projects (scheduling priority)

lhc (-0.00)
test4theory (-0.00)
gpugrid (-3.03)

that host hasnt been able to get work for lhc for the last two days or so. it gets steady work for t4t and gpugrid though. its inability to get work for lhc is not cache related, i only have one instance of t4t running on it and stopped all work from other projects to see if eventually it would get some lhc work so the cpu has been essentially idle for the last two days on that machine. i was gonna leave it free for the remainder of the weekend to see if there are any changes and monday ill set cpu work fetch back on for another project if it doesnt get anything for lhc by then.

ive been reading other threads about work quotas. im not sure if i understand how lhc enforces it but if my math is correct, there should be nothing preventing that machine from getting new tasks.

the other machines i have set to retrieve new work for lhc are getting work regularly. those have lhc scheduling priorities of:

-2.39, -0.05, -0.04, -0.04, -1.61, -0.11

i think youre right, its sorta a mystery to me too. i get work from non lhc projects with -0.00 (t4t) scheduling priorities though.

I just discovered that SixTrack can run on a 64-bit mac. I have two, an i7 and Core2 Duo. It is too soon to see if I have any crashes.

I hope I can be of some help.

Philip

hopefully youll have success. according to the applications page there should be a 64 bit mac version. according to the errors i got it seemed to me like my mac was using a 32 bit version but im not sure:

that error was on a mac mini with an i7 processor so i dont know if that machine may have downloaded the wrong application for some reason. i would assume it should have downloaded the 64 bit app? the boinc client runs in 32 bit mode on that mac but for other projects that have 64 bit apps, they run fine.

Post:
thank you for the warning.

The MAC version was indeed intended for Apple machines with Intel processors.
I think we need to analyze this one to see why it is crashing.

Sorry about the difficulties.

Igor.

i dont think the difficulties are based on the processor. the mac mini has an i7 and the macbook air has an i5, both of which are 64 bit i believe. the two machines are no more than a year and a half old.

if there is more information you would like me to provide regarding this, please let me know.

thanks.

apologies in advance if im posting this question in the wrong place. i looked at the q&a section for unix/linux related issues and the threads there all seem to be quite old.

i got pretty excited recently when lhc started having work again so i wanted to crunch on my mac too. attempts today to do this have all ended in errors for

this host's tasks and

---------------------

of the two macs, one is a mac mini and the other is a macbook air. both are running os x lion 10.7.4. im not too familiar with mac or unix/linux so any information you can provide youll have to treat me like a new guy.

this thread seems to indicate working towards some apps for mac. i dont know if the sixtrack app being used is the correct version. it would be nice to get these two machines running sixtrack. they have had boinc installed and have been running other projects for quite a while now so i know they are stable. just having difficulty right now trying to get sixtrack working.

thanks for any help or information you can provide.
