Other units have finished correctly as did one in the listing above. Does anyone have any suggestions to stop it, please? I have an Intel i7-3770 CPU @ 3.40GHz with hyperthreading. Mike |

That is a lot of CEP2 tasks to run simultaneously. What are your system specs, as shown during BOINC startup. Are your profile settings big enough to keep your system running? You can always check that by cutting your thread count in half.

Also look at the system requirements page at https://secure.worldcommunitygrid.org/help/viewTopic.do?shortName=minimumreq which asks for 1 GB RAM per CEP2 thread. As I suspected, your system has a lot less than 8 GB memory. CEP2 is very memory-hungry. Try reducing the number of CEP2 threads.

I have several CEP 2 crashed too.
----------------------------------------But in my case the message i got is different: Output file E214253_630_C.36.C31H16N2O2S.01246556.1.set1d06_ 0_0 for task E214253_ 630_C.36.C31H16N2O2S.01246556.1.set1d06_ 0 is absent.

With each WU requiring 1 gig RAM and you only having 2 gig it maybe cutting it fine, either give more RAM to BOINC or run only one CEP and see what happens....

Hello candid,
This does not ring any bells with me. Here is a typical SIGNAL 11 error: https://secure.worldcommunitygrid.org/forums/...ead,30167_offset,0#300160 As you can see on the FAQ at http://boincfaq.mundayweb.com/index.php?view=165 SIGNAL 11 can be caused by many different interrupt signals. I am interested in why you only have 3 GB of hard disk available for BOINC. As you can see, the system requirements at https://secure.worldcommunitygrid.org/help/viewTopic.do?shortName=minimumreq want 2 GB RAM and 4 GB hard disk for 2 threads of CEP2. These requirements are generally much bigger than are actually required, but if you start going below them you should carefully check your profile settings to make sure that everything is at 100% and not artificially lowering already small allotments of memory and hard disk.

Many thanks everyone for the quick replies.
----------------------------------------I am in fact running low on HD space, but by my experiece the 2 GB per WU are were more than necessary for my i7 with 8 GB RAM. But in this case I am running an atom from a USB stick with no real HD. that is why i have only 3GB 'HD' space for boinc. The software I used (lili usb creator) does not allow more than 4 GB and some has to be left for the system (ubuntu 12). I am now going to try to run one CEP only with some other type of wu (faah). Lowered to usage limit to 35%. I always check the option to leave app in memory while suspended. while writting this i got an error message from the OS: compiz failed. The OS is asking me to continue or relaunch the OS. I remember that I had seen this before and I did rever relaunch. Could this be (part of) the problem? Other wu such as faah and dsl did not fail because of this failure in compiz. Thanks [Edit 2 times, last edit by candid at Jul 3, 2013 12:47:07 PM] |
