    Genefer 3.3.4 now live
    The latest release of genefer (3.3.4) is now released on BOINC labelled as app version 3.20. The client will download the new app automatically, no action is required on your part unless you are using app_info.xml (if you don't know what this means, don't worry).The new version provides a speed-up of around 10% for AVX and FMA3 transforms for n=21, as well as providing support for multithreading. To enable it, create an app_config.xml file in your BOINC/projects/www.primegrid.com directory containing (for 2 threads per task)


    genefer
    -nt 2
    2

    cpuGFN21


    Any problems or questions, let us know! Please note that as the new release does not affect the OCL code, the GPU app versions remain unchanged.

    If you want to multithread you need an app_config.xml in your C:\ProgramData\BOINC\Projects\www.primegrid.com

    Use physical cores only (no hyperthreading) eg 2 in the example xml file below represents two cores, adjust as necessary.
    For GFN21's use the following:

    <app_config>
    <app_version>
    <app_name>genefer</app_name>
    <cmdline>-nt 2</cmdline>
    <avg_ncpus>2</avg_ncpus>
    <plan_class>cpuGFN21</plan_class>
    </app_version>
    </app_config>
