Hi I am getting these kind of mssages all the time:
16.11.2010 14:02:28 World Community Grid Task E200517_635_A.24.C19H16N2SSi2.43.3.set1d06_0 exited with zero status but no 'finished' file I believe the tasks are then restarted the Messages tel me to reset the project if this happens often I have already done this once. So resetting doesn't seem to help. Is this an error in the App? will it be corrected? Or should I just ignore this behaviour? What should I do? Thanks Thorsten |

Thorsten,
----------------------------------------plz, assuming you've seen them on previously completed tasks: 1. Open the Result log (status column link on Result Status page). Are there No Heartbeat messages - exiting or No Heartbeat .... 30 Sec? 2. If this is true, go to the Start Here FAQ index and visit the Zero Status and No Heartbeat topics. The cause is very likely an obstructive force on your computer, to include your system possibly just too busy during use and then best the client then being set to only compute during idle time when doing CEP2 tasks. It is not an application error. CEP2 jobs are heavy and for this reason the default is set to only run 1 at the time on any computer. --//--

I get them each time a CEP2 job finishes, and sometimes when other jobs finish too. It always bumps the other three jobs off of my quad core. A typical sequence looks like this:

I have no anti-virus or firewall running on that PC at all, which is devoted 100% to WCG (and Folding on the GPUs, but that uses practically no CPU time), so there are no extra demands on the CPU. But as you can see, the recovery is almost instantaneous on the jobs that get bumped (I have "leave tasks in memory" checked), and it apparently does not affect my results that I can see. However, if the SSD is that limited, it might not be doing so well when reading/writing intermediate results that I don't see in the message log, and so I would like to get it fixed anyway.

Well I do have the no heartbeat stuff.
And I turned off time synchronization with the internet server. But that didn't help. I don't get why this happens because the application is demanding. Who cares about the machines performance? The applicaitin should just take al the idle cycles and just work with them. I have 4 GB Ram (windows XP) so more like 3,5 GB and 8 cores. And who cares about the IO? The harddrive seems to cope fine the System runs with good speed. Well I guess its just annoying that I cannot run more than 1 Clean Energy process. |

Well I found out that I can do 4 tasks quite well without having any problems maybe more.
But if I do 8 tasks then I get these heartbeat problems. So I think it would be great if it would be possible to regulate in some way how many tasks of the Clean Energy Project are executed at one time. So maybe thats something that could be implemeted in the future. |

I am able to solve the problem (see above) by the use of FancyCache, which has eliminated this message no matter how many CEP2 jobs I am running.
http://www.ocztechnologyforum.com/forum/showt...ing-new-hybrid-disk-cache The CPU % (as measured by BoincTasks) is now up to 97 percent even if four CEP2 jobs are running on my quad core. A write-cache only is sufficient for me (256 MB, 30 second write latency should be more than enough), though you can try both read/write. I have found the "Disks" version is more stable on my PC, though the "Volumes" version works for some people and can select a single partition on a disk for caching. But the Vertex 2 will raise that percentage even higher when I get around to installing it after SP1 comes out for Win7. |
