GPU plotting 10TB ... 3 weeks!? please help
-
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 ...
-
@Jackk78 Ignore the estimate - it's way, way off. In direct mode the plotter builds the entire file, then fills it in. The building process takes quite sometime - 5TB takes about 12 Hours. While it's building the file, the time estimate will just get worse. Once the actual plotting starts, the estimate will decrease, but will always be longer than it's actually going to take. For 10TB you're looking at around 2 Days. The GPU plotter was telling me a 5TB plot was going to take 124 years - it took 24 hours.
-
@haitch If it will be done in 2 -3 days, it is not a problem. I could not use the gpu plotter, because the speed was very low, at around 1200 nonces/min. Now, I am using the wplotgenerator and it is working with 7258 nonces/min, which is much much better. Not the best, but i think it will do the job. I will wait the 3 days, to see what is happening, and if it will not do it right, than I will start from scratch with smaller size plot files.
-
@Jackk78 Thats what I was saying though - the stats on the GPU plotter in Direct mode are completely bogus. At the start of my last plot (15TB over three drives) it was showing 1000 Nonces/min, estimated plot time 124 years. It finished in 24 hours with a final plot rate of around 21,000 Nonce/minute. With a reasonable GPU the GPU plotter is much faster than the CPU plotter - just ignore the stats, they're a lie.
-
@haitch Well, I did not knew this, so I changed the GPU plotter to CPU. Everybody learns from own mistakes :) Now, since I started to plot the drive with the CPU plotter and it is working, I think I will leave it to do its job. If something will go wrong, than i will change back to GPU plotter and smaller sizes.
