    Hello yours,
    To understand my question here the configuration of my machine:

    Processor: i7-2600 3.4GHz
    Memory: 8GByte
    GPU: Geforce GTX590
    OS: Win7 64bit
    GPU-Driver: 314.07 (Multi-GPU Modus deactivated)

    I'm running following Projects, that using GPU
    - seti@home
    - Einstein@home

    The other Projects using CPU are
    - lhc@home
    - cosmology@home
    - world community grid

    Boinc Preferences:
    - On multiprocessor Systems, use at most: 75.00 %
    - use at most : 100.00 %

    So, that's my configuration.

    I have configured, that seti@home and Einstein@home using 0.33 GPU, so i have normally running 6 WU's (0.2+0.33NV(d?)) parallel on my 2 GPU's.

    Since yesterday i have only 4 e@h-WU's running parallel on the GPU's. Why?

    If i suspend all Projects except einstein@home, boinc start 2 new e@h-WU's, so i have 6 WU's on the GPUs running. If i resume the other Projects, so i have 6 WU's running on the CPU and only 4 WU's running on GPU's. The 2 new started WU's are set to "waiting to run".

    Anybody an idea?

    Thansk to all

      Hi Juergen

      I don´t think i have any answers but another possibly unrelated observation.

      I had a look over the tasks you have submitted and noticed a larger than usual number of invalid results.

      All invalids i checked appear to be from GPU#1, both BRP4G and BRP5 affected.

      May i suggest you post the boinc messages for the boinc-meisters to see.

      0.33 x 4 = 1.32 CPUs

        0.33 x 4 = 1.32 CPUs required

        You've over committed the CPU. BOINC normally will allow over committing (for GPU apps) up to 1 or 1.5 CPUs, depending on the version of the client. If you allow 87.5% processor use it will schedule more tasks at the same time.

        He's already set it to 75%. A

          He's already set it to 75%. A few things I can think of right now:

          - are any WUs in high priority mode?
          - did SETI change the app, so that your setting no longer applies?
          - did you configure Einstein using the website or an app_config.xml? In the latter case a new app may be out which is not yet configured in the file
