XPlotter for optimized plots (CPU)

Blago

@k.coins When ploter starts - it calculate first chunk of nonces. After calc done - it start write first chank and in parallel start calculate second chunk of nonces. Then wait until writing done...
If you see gray line - plotter calculated nonces before writing done and it wait while writing done (wasting time).
You need increase memory usage.
BUT! from my tests (HDD):
writing time of 6 * 800 nonces ~= 45 sec
writing time of 6 * 1024 nonces ~= 45 sec
writing time of 6 * 1030 nonces ~= 90 sec
writing time of 6 * 2048 nonces ~= 90 sec

@Blago How can I check if my Plot files are good?
Are my current methods, plotschecker and running it through your miner, still valid?
I'm asking because you'r using a new way for writing to disk.

My PC crashed while plotting a 4TB disk at whole. The plot file checks out so the plotter seems to have finished.
But 4TB in about 12h, that just can't be!! ⺌∅‿∅⺌ !!

I was using

@setlocal
@cd /d %~dp0 
XPlotter_avx.exe -id 107189002634585473 -sn 830522688 -n 15260960 -t 6 -path D:\plots -mem 20G
@pause

on an i7-6700k

@nixxda plotschecker can't help for optimized plots.
Just run again bat

@setlocal
@cd /d %~dp0 
XPlotter_avx.exe -id 107189002634585473 -sn 830522688 -n 15260960 -t 6 -path D:\plots -mem 20G
@pause

and plotter will check and continue writing. (each plot, created by XPloter 1.0 contain info - how much physically written nonces)

@ZapbuzZ when you make plot (fill drive mode) - xplotter create plot with size as possible.
If you interrupt creation - you need change bat.
for example:

XPlotter_avx.exe -id 107189002634585473 -sn 830522688 -n 0 -t 6 -path D:\plots -mem 20G
plotter create 107189002634585473_830522688_15260960_15260960
interrupt plotting
change bat to XPlotter_avx.exe -id 107189002634585473 -sn 830522688 -n 15260960 -t 6 -path D:\plots -mem 20G

if you did not change bat - XPlotter will try create a new plot, but you have not free space for it

@gumbogumbo the -mem parameter is what you'll want to play with. I think it will only use half of what you have available, no matter what you put in for the value.

But just as an example, if you have 20 Gb of RAM, try using "-mem 20G" to see how much xplotter will actually utilize.

@gumbogumbo It just goes on the command line, so from Blago's example:

XPlotter_avx.exe -id 107189002634585473 -sn 830522688 -n 0 -t 6 -path D:\plots -mem 20G

@gumbogumbo said in XPlotter for optimized plots (CPU):

The only place I see that text is on the top bar of the window.

Presumably that is because you are looking at the actual program window (exe), whereas you should be editing the .bat file that launches the .exe, and then launch the program afterwards.

EDIT

With me the file that needs editing is called "runthisasadmin.bat". Right click it, and choose 'edit'.

@gumbogumbo sorry I didn't specify where to edit the parameters... My bad!

turns out my PC crashed at 12%! (I had many many other things running!-)
But restarting the plotter worked like a charm! about 13h later the whole disk was plotted.

I'm still a bit suspicious however!-) File size was allocated at the beginning but are there really all the nonces in there?! Is there no way to check except winning Blocks with it?!

tross

@nixxda maybe plot checker? I look at it this way if the file is to cover whole hdd then it would show no free space. So something has to be there. Plus its a file not a partition so some data must be there if it taking up space.

@tross
does not work unfortunately!-) Only thing right now is confirming that Xplotter has properly finished I'd say!
And some trust in Blagos code!-) And in your own abilities of course!!-) (?)

PlotsChecker only checks filename and something and since the file size is created/allocated at the beginning it always stays the same.

Blago outsmarted himself! hihi! damn that thing is fast!

Blago

@nixxda
if you run XPlotter again and will see something like:

= plot is complete

Plots checker did not help for check optimized plots

if plot not complete - it contain garbage (deleted files)

@Blago what is this "Failed WriteFile (code = 21)" I'm getting?

Happens again shortly after rerunning xplotter after the initial fail
