Hi guys i got question got the cuda chip to work right.! however when in advanced mode on the client and i look at time elapised eg. it mite say 2hrs 20mins 100% done ,now if i switch to simple veiw it will say eg. 186 sec why ? and what am i supposed to believe is correct the 186sec or 2hrs 20 mins . this only seems to be happening with CUDA done units .?????????.I believe it is takeing 2-4 hrs to complete a unit done with CUDA |

I think you'll have to differentiate between CPU- and elapsed time (see properties of tasks). Gruß, Gundolf Computer sind nicht alles im Leben. (Kleiner Scherz) SETI@home classic workunits 3,758 SETI@home classic CPU time 66,520 hours |

Elapsed time equals real time, wall-clock time, or perhaps better understood, your watch. CPU time is only showing the amount of time that the CPU has taken on a task. Since CUDA runs on your GPU, it will not show much CPU time. The CPU is only used for transferring data to the videocard and back. Since BOINC cannot see how long a task takes on the GPU, it will only show CPU time in simple view, while in advanced view it will show the wall-clock time. The real time that the task takes on the GPU. It won't transfer this time back to Seti either, so in your tasks tables it'll show the CPU time. |
