Well, I have one of the new CELLGA_SHORT WUs running for over one day and 5 hours now, still showing 0% done. Is it save to assume the CPU time is wasted and the WU will never complete? ;-) Should I abort it? It's this one - http://www.gpugrid.net/result.php?resultid=555615

Ok, thanks! Aborted it now after 1 day and 16 hours... My nice credits... ;-)

Maybe it wasn't a problem with the task but with my PS3.
Now I got a TONI_CELLGA task that also seemed to hang because it showed no progress after 20 minutes, but after a reboot it is running fine now...

Hmmm, after 20 minutes the next task was hanging, this time a TONI_CELLGA_MED - http://www.gpugrid.net/result.php?resultid=565176. I aborted it, and will try another task...

Thanks Gianni, but I think I just found the problem...

I just started my PS3 again, started BOINC and got a hanging task again. It was running for 2:37 minutes and then the CPU time was hanging with 0% progress.

When I started BOINC it was running CPU benchmarks, but after a few minutes it was running the benchmarks again. The problem is boincmgr showed "suspending computation - running CPU benchmarks", but "top" still showed 154% CPU for cellmd2_5.03_po. Another thing I noticed was the time shown in boincmgr. First it was wrong and when it started the second benchmarks it showed the right time (see screenshot). So I don't know if the task was hanging because it wasn't suspended during benchmarks or because the system time has changed. Weird thing is NTP is turned on, and the system time should always be right...

I think I'll try to delete the whole boinc dir and redownload BOINC and if that doesn't help I'll try a new YDL 6.1 install...

Have same problem;

http://www.gpugrid.net/workunit.php?wuid=399536
http://www.gpugrid.net/workunit.php?wuid=405292

lot's of hrs and energy wasted again.
I'm not requesting new WU for a while and only do work for yoyo.

Thanks for looking into the problem Toni!

I previously deleted the BOINC directory, redownloaded BOINC and got a GRA_US task. Seems this one is running ok now. It`s almost at 10% after 4 hours crunching...

Hi TG,
No benchmark was running during start and the time I cancelled the WU, below I inserted the log from the moment I started till I cancelled it.
Hope you can fix it or at least build in a max running-time for certain WU.
Will follow the forums to see if things get better and I'll be back than.

Could it be that this problem occurs when more than one project are using the PS3 (maybe it's related to task-switching)? I've been crunching on my PS3 for a couple of months without problems but had this problem yesterday once I attached BOINC to yoyo@home. I aborted the WU and got another one but this one seems to be hanging too. Here are the links to the WUs:

http://www.gpugrid.net/workunit.php?wuid=407696
http://www.gpugrid.net/workunit.php?wuid=407774

I think all the WUs, from PS3Grid and others, hang, at least that's what happened with me. I was looking around and found a newer BOINC client optimized for the PS3 (http://www.dotsch.de/boinc/boinc6219_10.linux-ps3.tar.gz), unfortunately it's a command-line version and I tried to get it to work with BOINC Manager but it didn't work. Maybe an update to the current PS3Grid BOINC client (whether using the one mentioned above or otherwise) would fix the problem?

Just to be helpful to another BOINCer at least on my machine the hanging WU seem to be specific to gpugrid. If you set the resource share for yoyo to say 3E+38 (a huge number) and gpugrid to 1 then your ps3 will happily only crush yoyo WU and will not hang. The problem only seems to occur when the PS3 starts working on a gpugrid WU. I am not sure but the problem also seems more pronounced with the memory stick version (what I run) as compared to YDL but I think it occurs with both at times.

just joined the gpugrid; first wu is hung 0.0%

Thu 30 Apr 2009 04:48:38 PM EDT|GPUGRID|Starting task 5-TONI_CELLGA_MED_9-0-2-RND0374_0 using cellmd2 version 503

posted because the admin mentioned trying to discern a pattern. I have not tried another ps3 based project. I just setup the machine with ydl6.1, basically vanilla.

I guess I picked a bad day to join. I booted; no worky. aborted. started another, no worky. then I see a message suggesting I joined the project with the wrong link, the one from the website. so I tried again, new wu: Thu 30 Apr 2009 05:20:10 PM EDT|GPUGRID|Starting task 638000-IBUCH_GRAUS-1-100-RND2278_1 using cellmd2 version 503

no worky. 0.0% I just suspended the wu as I will my effort for today.

I am open recommendations regarding this project and/or ydl6.1; I am new to both.

thanks.

1 WU since a week i crunched for gpugrid and hung, +16hrs and 0%

http://www.gpugrid.net/result.php?resultid=598295

I have promised to be political and will simply say the PS3 portion of this project is experiencing "growing" pains and gpugrid WU often hang. The problem is not with your setup (wish it was more clear so people don't waste their time debugging a universal project problem).

after 7 finished WU this one went +39hrs with 0% progress so I canceled it.

Maybe next can help with hanging WU:

This http://www.gpugrid.net/result.php?resultid=694578 crunched 1st 24hrs with 0% progress. Then I restarted linux from the menu the way you would see the blue screen but without needing entering password and ROOT as user. After the reboot within an hour the progress was counting and it finished positive.
There was a donor system that did the normal hrs for this WU.

it's getting boring that things aren't getting fixed
____________

Could it be that's it's heat related my WU often hang?
I notice that with higher room temp (above +21°C) I do have this hanging.
When it's 20 or below it could crunch for weeks.
I've NOT this problem with yoyo!!!!

BTW an other one wasted 2 full days of energy ... so I cancelled requesting work for the moment (26°C inside)

i've since i last started ps3grid, with yoyo suspended no problems.... it looks sofar good ....but if it's multi-project related, it isn't nice of this project to not fix it. I'm MORE satisfied if i could get yoyo back at 10% so the ps3 could ask work from that project if gpugrid runs out,server hangs ,....
