Sorry if this has been addressed elsewhere, i skimmed through and did not see it. Basically, Everything seems to be running fine. Only problem is the time running stops at between 20 and 40 seconds. All WU's report as being crunched in 20-40 seconds Some Samples: http://setiathome.berkeley.edu/result.php?resultid=1106612883 http://setiathome.berkeley.edu/result.php?resultid=1106612879 http://setiathome.berkeley.edu/result.php?resultid=1106612838 http://setiathome.berkeley.edu/result.php?resultid=1106612835 http://setiathome.berkeley.edu/result.php?resultid=1106533366 Each actually took about an hour to two hours Host info is : Name Phaedra Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz [x86 Family 6 Model 15 Stepping 11] Number of CPUs 4 Coprocessors [CUDA|GeForce GTX 260|1|895MB] Operating System Microsoft Windows XP Professional x86 Editon, Service Pack 3, (05.01.2600.00) Memory 3322.75 MB Cache 244.14 KB Swap space 5206.93 MB |

Time reported is CPU time only. As the column it is in states.... Do you Good Search for Seti@Home? http://www.goodsearch.com/?charityid=888957 Or Good Shop? http://www.goodshop.com/?charityid=888957 |

What P&B means is that although you crunch with the GPU, only the CPU time is counted by BOINC. BOINC isn't able yet to count the amount of seconds the GPU is taking on such a task. With a minute part of the CPU being used to transfer the data about the task to the GPU and back to the disk, this is the amount of time that is showing as the "run time" of the task. |
