GPU plotter Help



  • @Propagandalf
    Yea I was doing litecoins to. But I just turned that off cause I need to pack that machine for the move to Midwest.:) My burst machine will stay running until I light the torch and walk out the door:)

    @Propagandalf I generally set stagger to = 0.5 * RAM, so in Redmogul's case 8GB. If you're plotting multiple files at once, divide this by the number of files being plotted - eg if plotting 4 files - 2GB each. The NVRam setting goes into the devices.txt and is per device, so it doesn't matter how many files you're plotting, just set it for that device.

  • Thanks for the reply. For non-technical people, it can sometimes be quite difficult to relate to all the different values and calculations. I have had a hard time understanding how stagger works and how to calculate it my self, but if I understand you correctly now, this is how we should think and plan for setting up stagger:

    Finding stagger (the next blockbuster film from CryptoPixar)
    1: Find out how much RAM is available in your system (remember that even though you have for example 8 GB of ram installed, you might already be using 3 GB for other processes, which leaves you with 5 GB available). RAM should not be confused with NVRAM, which is your graphics card's dedicated memory, and is not part of this equation.*

    2: Decide how much of your available RAM to dedicate to plotting, for instance 4 out of 5 GB of available RAM.

    3: Understand that 1 stagger is a unit measure of 256 KB of RAM memory. Therefore, if you want to run an exact calculation to understand the conversion from memory to stagger, you need to find out how many KB the 4 GB of RAM you want to use consists of (break the numbers down to smaller units). 4 GB equals 4096 MB equals 4194304 KB.

    4194304 KB (RAM) divided by 256 (stagger unit measure) equals 16384 (stagger). This will be your correct value for stagger, based on the above example from section 1 and 2.

    4: Know that it is easier to simply find out your amount of available RAM in MB and multiply it by 4 (4096 x 4 = 16384).

    5: If you decide to plot several files at once, you need to divide your stagger by the number of files being plotted. For two plot files it would be 16384 stagger divided by 2 equals 8192 per plot file.

    6: Start plotting if you have got the other values worked out such as

    4401562696129194441 - replace with your numeric account ID
    106430464 - nonce to start at, do not overlap (if this is your first plot use 0)
    7618560 - number of nonces to plot, must be a multiple of the stagger (the next field)
    16384 - stagger, where each unit represents 256 KB of memory, which in this case totals 4 GB (4096 MB)

    Example output: gpuPlotGenerator.exe generate direct u:\4401562696129194441_106430464_7618560_16384

    Note: My above calculations were based on the binary value of bytes, which differs from the decimal value.

    *NVRAM settings are put in devices.txt and is per device, so it does not need to be changed according to how many files you are plotting simultaneously.

    16384 - stagger. Each 1 = 256 KB of memory, so divide by 4 to get amount of memory to use. In this case it's 4GB (4096 MB)

    I am not sure if this exists already in the FAQ section or if it is needed, but feel free to use this if it is of any help to newbies.



  • I am having problem with GPU plotting, every time I start it would hang after 5

    My Info
    Window 7
    GPU: R9 280x
    gpuPlotGenerator.exe generate direct g:\xxx_0_3813375_8196

    Thanks in advance

    @FattySnorlax Thats how it works ... gpu creates plots in memory ... if memory is full they get written to disk ... and repeat.



  • @FattySnorlax Unless you mean that it completely stops and for some reason does not create the file as it should. In system task manager you could monitor both the CPU, Memory and Disk to check if it works. Like luxe says, it will "occupy" memory resources first, and then it will move over to occupy disk resources, and then move back etc.. Maybe the CPU is involved too, but probably not much.



  • Thanks for the quick reply, I will try when I have the chance and reply here again. :)



  • Just tested and it stuck in the beginning 10-20 second (I have waited 10 minute and still same), GPU and CPU usage dropped to 0% but physical memory is stuck at 69%, tried again on different hdd still same, might it be GPU problem?

    Thanks again in advance.



  • @FattySnorlax I don't know, maybe @luxe knows?


  • admin

    @FattySnorlax are you plotting in direct or buffered mode? In buffered, which creates an optimized plot, the miner will plot the first set of nonces, then build the complete file that the plot will go into. Depending on the size of your plot this can take a LONG time, and while it's happening the plotter will appear hung - CPU/GPU activity will go to about 0, the % complete will not move. However, if you go into Resource Monitor -> Disk Activity, you'll see the app is actually writing a lot of data to disk. Once the full plot file is built, then the CPU/GPU and % will get really active as the plot file is "filled in".



  • @haitch I am currently plotting direct, but you are right. Although everything seems to go 0% and stuck but my hard drive used space is increasing so I guess its working :) Thanks for everyone's help.

    Anyway it take about 24 hours for 2 x 1TB hard drive, is that normal? I plot both at the same time.



  • @FattySnorlax It's definitely not unheard of! It depends on a lot of factors :)


  • admin

    @FattySnorlax From memory 24 hours for 2 * 1TB is on the high side, but depending on your CPU/GPU/Drives could be reasonable.



  • @FattySnorlax make sure it isn't formatted for FAT32. Mine was when I first started and it took me a while to fix it. If it is, I suggest formatting it for NTFS. WARNING. YOU WOULD LOSE ANYTHING ON THE HARD DRIVE IF YOU DID THAT.

    please could help me generate a plot correctly?
    already own some plots generated more cpu is giving error

    Thank you very much in advance



  • @trincaxt By looking at the last picture you uploaded, it looks like you found at least one deadline (dl confirmed), but your plots are overlapped. In the same picture, you can actually see a link to where you can find a "plot overlap checker" tool. Maybe you could try that and see if it can "fix" them.

    Are you having other problems than overlapping plots when generating your plots? If yes, post the contents of your jminer.properties file, please.

  • I created a plot of 48 gb with cpu from the copies I have 15 files



  • This post is deleted!

    I'm not quite sure what you mean by this, could you please explain?
