Plotting slowing down



  • @Garbear ,

    I use 8 cores on each of 3 concurrent plots. Only 1G or less of RAM is necessary. I set the priority for these 3 to below average so as not to hog the system when some other program needs CPU time. As long as any one of the 3 is yellow you are effectively getting max nonce/min which for me is about 8300. Those 8300 are spread across the 3 files.

    If you do what I say here, you will plot 3TB per day at your stated 7900/min.

    But what do ur write speeds look like? Do they start out maxed then drop to 5-10mb/s like mine do? So ur doing like 3 cores 1 plot, 3 cores 1 plot and the last 2 cores the 3rd plot?

    How do u change the priority for the plotter? It's a plot only rig for mine so I dont have to worry about other stuff needing cpu time.



  • @Garbear , yes they do, that's why I invented this system. It is specifically for writing to SMR drives. Try it, you won't be disappointed. I wrote up an entire thread about this called "how to get max nonces ...." or some such title.



  • @rds I'm looking for it now lol

    I'm start Xplotter as Admin 24 hrs ago (2Tb WD Re, starting speed ~5100 nonces/min), now the same speed

  • @Blago , 5100 n/min is 2TB (7,630,000 nonces) a day, and that's what you did. So I bet the WD Re is not an SMR drive.

    To plot 2TB a day at 5100 n/m on SMRs, plot 3 or more files simultaneously.



  • @rds Can I plot simultaneously with XPlotter? I have 4 threads and 4 gb ram, how i setup bat files?



  • Personally I've found plotting to an internal drive and then copying the finished plot file to an external to be a much faster and more reliable way of working.

    USB3 externals are picky and have tighter tolerances, so the nicer I can treat them the better I think.

    I can build on an internal at full speed and copy the finished file at 100MB/s in one single stream to the external.



  • @hgrh , use 4 threads, 512M ram and below normal priority. Let me say my 3 file system has only been tested with 3 files on 3 separate drives. Not sure how it would work (speed increase?) if the 3 files are on the same drive. Here is a example bat file for 3-1TB files on 3 different drives. If you only have one drive, adjust the paths as necessary.

    start "" /belownormal /b /w "c:\burst\XPlotter.v1.0\XPlotter_avx.exe" -id 12345867970884553089 -sn 6000000000 -n 3815000 -t 4 -path c:\burst -mem 512
    start "" /belownormal /b /w "c:\burst\XPlotter.v1.0\XPlotter_avx.exe" -id 12345867970884553089 -sn 7000000000 -n 3815000 -t 4 -path c:\burst -mem 512
    start "" /belownormal /b /w "c:\burst\XPlotter.v1.0\XPlotter_avx.exe" -id 12345867970884553089 -sn 8000000000 -n 3815000 -t 4 -path c:\burst -mem 512



  • @rds when i use xplotter_avx.exe it does'nt work
    have to use xplotter_sse.exe, what is the diference?



  • @hgrh , if your hardware won't support avx then use the sse file.

    I edited out the /w in the original lines. /w is for sequential writes, the bat lines shown above will all run at once as written now.



  • i can get to 8 gb ram, what will be the configuration then??



  • @hgrh , you could bump it up to 1GB but more ram in the bat file will not increase your speed, so get it if you need it for another program, but 512MB will work fine.

    I used to do that but now with my 3 file system I can plot direct to SMR drives as fast as you can to a PMR drive and skip the transfer time, which is not insignificant.



  • Thanks!....



  • @hgrh , I just did a little test with 3-30GB files on the same drive. It did not appear to work like my 3 files 3 drives method. I would not try to use this method on a single drive. You will probably get the same results as using 1 plot to 1 drive.

    Also, I showed the bat file above with all 3 commands in a single file. While this should work, I don't like it because you can't see the progress of each individual file so I would suggest, as I do, to make 3 separate bat files with each drive command line(s) in it. Now if you do that and want to plot each drive with smaller files like 5-1TB file for a 5TB drive then fill the batfile with the 5 lines and use the /w so one file finishes before the next starts. However, you run all 3 bat files at once, so you can see the progress of 3 files concurrently.
