GPU plotter questions



  • ok i managed to get a compatable gpu to plot with.
    it has 2gb onboard memory and i wanna make a 4tb plot.
    I have calculated the amount of nonces i want to write and the starting nonce but thee following in help section blew over my head i was wondering if someone knows more how to plot with these instructions and can type a working example for me:

    • writerType: Writer type to use to write the output files.
      Specify [buffer] to stack nonces in a buffer before writing them.
      Specify [direct] to write nonces directly to files.
      The <staggerSize> value will be used to configure the temporary RAM buffer size.
      The output file will always have <staggerSize> = <noncesNumber>.
      • plotsFiles: A space-separated list of output files to generate.
        The file name has to be [<address><startNonce><noncesNumber>_<staggerSize>] with:
        - address: Burst numerical address.
        - startNonce: First nonce of the plot generation.
        - noncesNumber: Number of nonces to generate (must be a multiple of <staggerSize>).
        - staggerSize: Stagger size.

    the following is info i wanna put in

    starting nonce 400000001

    number of nonces is 800000 per 20gb so 12024264 would fit most of 4tb

    gpuplotgenerator generate [buffer | direct] <your numeric id> 400000001 12021760 8192



  • that simple? thanks mate :)



  • I explained it here, best regards



  • output i got was [ERROR] Unknown writer type
    my gpu card is nvidia GT440 has opencl v1.2 2gb memory and a frustrated owner -lol-


  • admin

    [buffer | direct]
    does mean use either 'buffer' or 'direct' ...
    buffer - create plots in memory and if mem full write them to disk (for best speed)
    direct - create/reorganize plots on disk, leads to optimized plots but is quite slow

    @ZapbuzZ You need to modify your devices.txt to match your card.

    run gpuplotgenerator setup , then 1 to list your card, then 3 to configure it.

    Save it and try again.



  • i got it matched and typed: gpuplotgenerator generate Buffer 400000001 12021760 8192 same error



  • could it be just not supported? i tried the buit in gpu too it is AMD same error :\



  • i must be missing something here

    @ZapbuzZ do gpuplotgenerator setup, do 1, then 2, and post a screen shot

    @ZapbuzZ That looks correct, what's the exact command line you're using ?



  • gpuplotgenerator generate buffer myid 400000001 12021760 8192


  • admin

    @ZapbuzZ That's what I get for posting before having my coffee ...... it should be:

    gpuplotgenerator generate buffer <drive leter>:\myid_400000001_12021760_8192



  • now i got error invalid filename
    where does filename fit in?

    my command was : gpuplotgenerator generate buffer (my id number) 400000001 12021760 8192


  • admin

    @ZapbuzZ the filename specifies the parameters the plotter uses - post the exact command you're using, you can post the numeric ID, no one can do anything with that, except send you Burst ....

    @ZapbuzZ do:
