XPlotter for optimized plots (CPU)
-
@Blago thanks! That's why it has taken an eternity for me to plot only 2 TB, I don't know if it deserves the pain to start over and do it again... Can it have an impact on mining after if I keep plotting with an small unit size allocation?

@Blago I am doing 10.5k nonces/min, but the HDD writing scoops is taking an eternity!

No, see results https://ejrh.wordpress.com/2012/10/26/cluster-size-experiment

start plotting with Admin's rights?
for me writing 6*1024 nonces takes ~30 seconds
-
@Blago yes with admin rights.

@Blago what is the best allocation unit size when formatting a drive for later plotting? I chose the default one, but I am afraid it performs much more slower than choosing the maximum allocation unit size. Any input on that?
I have read exactly the opposite in another thread https://forums.burst-team.us/topic/1900/large-scale-burst-mining-operation. Here, they put forward that 64k cluster size may make the write speed slower, and that using the default cluster has fixed it, according to @nixxda. I am currently plotting 8TB drives using gpu plotter in buffer mode with 64k cluster, and it started fast, but has since dropped almost to a halt (10 MB/s). This is a different plotter than xplotter of course. I have not been able to test with default cluster size yet.
@luxe is it possible to run gpuplotgenerator.exe with admin rights through a batch file, and will it make any difference?

@Propagandalf thanks for your input. I think the answer was given before with the link @Blago provided https://ejrh.files.wordpress.com/2012/10/copying1.png
If you have big files to copy it is recommended then to use 64kb as allocation unit size for the drive, and the contrary applies to moderate or small files. Although I am not sure now how does this apply here, as each nonce has a small size... According to @Blago it is recomended for Xplotter.exe to run it as administrator, as it goes faster. Just right clicking the batch file and run it as administrator :)

The other discussion was about SMR disks specifically. And as I remember my tests about cluster size were not conclusive! SMR's are using the periphery of the disk as an fast buffer (non smr) and everything inside is smr (overlapping). I read somewhere that all of this (and the controller) is very likely optimized for the default cluster size!
But we didn't have Xploter at the time! I might replot one of these disks yust to see how it "behaves"!-)

@Blago Wow 1.0 is way better than the GPU plotter finally I can have optimized plots good work.
Edit: Just finished plotting 6TB in one big plot file took 35 hours.
-
@blago At first, thanks for your hard work.
I have a question: Is there a way to pause the plotting and resume later. Or at least change the thread number on the fly so when I need to work I can decrease, say 2 threads, and at night I can increase to full threads.
It takes too long and I have to use my PC also for work (CPU intensive 3d modeling and rendering).
Thanks again :)

@umutusu In task manager you can adjust the affinity of the plotter application - take away cores from it when you need them, give them back when you don't.

Thanks again :)you can also close the window to end the plotting and just run the bat file again when your done using your PC. It will continue where it left from plotting.

I just wanted to thank @Blago for his work here it was so easy to setup and use.
All this work is super appreciated
@someone give this man some cookies
-
I <3 @Blago lol - as soon as I come up on some some coin, you and all the other devs will get a bonus

I am having problems with write speeds on my drive can anyone help? I have tried messing with the threads and mem settings but cant seem to get it right. The plotter will go through the first set of nonces fine staying completely yellow with generating and writing. But then after the first set of nonces get written my write speed drops down considerably anyone know what could be causing this?

@vile You run bat as Admin? NTFS?
screenshot pls
-
Yes running as admins and ntfs

wow that picture didnt work well hold on
