GPU plotting 10TB ... 3 weeks!? please help
-
Hello again guys. I bought a 10 TB internal HDD for mining, but unfortunately the plotting is not working as I suppose it should. After 8 hours off plotting, the plot file is at 17 GB and it was working with 1115 nonces/min. This is way too slow and it will take forever.
This is my system :
Win 10 64 bit ( fresh install, new drivers, new OpenCL)
16 GB Ram
AMD Fx 8 core processor
ATI Radeon HD 7870 Video card
and the new gpuPlotGenerator-bin-winx64-4.0.2 configuration files:
devices : 0 0 5120 256 32768
makeplots.bat : gpuplotgenerator generate direct G://burst/plots/my nr id_0_35061760_32768
Please tell me what is wrong with this configuration. I calculated the nonces, the stagger nr according to the HDD size and memory. Is something wrong there? Please advice, because I can not do more on my own. Thank you
-
Try using smaller stagger size.
-
37268, is that a right stagger? how about use this on your device 0 0 1024 128 8192?
-
I have tried with 8192. The same result.
-
I have tried with : 1024, 2048, 4096, 8192 and the max 32768. The maximum speed achieved was 1214 nonces/min.

@Jackk78 Try CPU plotter, use all core available and use /async in wplotgenerator. It should be faster.
-
I just started the wplotgenerator, it is much better than with the gpuplotter, I get now 7297 nonces/min with the following conf
wplotgenerator mynrid 0 37653504 15232 8 /async
Is this ok, or there is a better configuration for it? What do you think?
Thank you
-
@Jackk78 I think you can get faster speed, try smaller stagger size and decide the best for you.
-
@Jackk78 for 16gb ram I use 64000 and when I async I change it to 32000 . But I wouldnt use max ram I always try with 75% total ram
try 12 gb ram or 48000 and async 24000
-
@Jackk78 The plotting speed is limited by the speed of your harddrive ... is it attached via USB2!? However this could be a bottleneck, too.
Btw. there is a more Up-to-Date version of the gpuPlotter:

@luxe no, it is a brend new internal SATA HDD
-
Ok, than ... are you sure you have specified you deviceId correct ... maybe you currently use cpu and not your gpu?!
Maybe post a screen of the gpuPlotter running/command line.
Also you will get higher speed with 'buffer' instead of 'direct' mode, but not optimized than.
-
Since it is working now much better than before, I think I will leave it as it is and wait 3 days to finish plotting. If I make any changes to the stagger, I will have to start all over again and if it will not work any better, than I will lose 8 hours of plotting, which is not a very good option. Unfortunately, i don`t know what a bottleneck means in this case
-
The bottleneck is the slowest part ... think about making multiple smaller parts, e.g. 2TB each, next time ... lot of things can go wrong plotting over multiple days.
-
@luxe In another topic I ask this question, and somebody suggested that it is better to plot the drive without splitting it in smaller parts, that is why I started to plot this way. And this is exactly why I asked. Now, i will know what to do next time. Can you please tell me what happens if I stop the plotting process and resume it later? I will have to start all over again, or it will resume from where I left of?
-
You can not resume it later ... if you stop it, you have to repair/rename it with https://forums.burst-team.us/topic/348/plotschecker or delete it. Or live with the effects on miner ...
I would not suggest doing 200 files or something but splitting in a few parts is no big deal ...
-
@luxe ok, thank you for the advice. Can you please help me to configure it in smaller peaces knowing the system I have and the disk size? It would be huge help. Thx
-
@Jack78 you could use this https://forums.burst-team.us/topic/338/nonces-calculator-for-plotting-v3-0/7 or https://forums.burst-team.us/topic/46/batch-plot-generator-win-linux
But sure i can assist if you have questions.
-
@luxe ok, thank you. I used the nonce calculator to determine the exact amount for the whole hdd. If I make lets say 5 * 2 TB plots, after the first one is done, I can use it to mine while I am plotting the rest?
-
Should work, you can even mine a plot that just gets written ... but i would not do that. I would create a plotting folder and copy finished (on same drive) to 'mining' directory known to your miner. On mining it could slow down plotting ofcause ...
