xplotter and gpu plot generator - different filesize
-
Hi all,
i have generated plots with an size of 1TB using two different tools (xplotter and gpu plot generator). Both in the newest version.
But i haven't expected to get different plot sizes. It seems to be an startnone inclusive exclusive problem.
Can you help me with that? i'm new in burst minging. I don't wanna replott all the data.GPU Plotter: 1099511365632 Bytes XPlotter: 1099511627776 Bytes Difference in Size: 262144 Bytes (256 KB) i decided to use files with 4194304 nonce and 4096 stagger size. (~1TB) XPlotter params: ... XPlotter_avx.exe -id 12878149936960097564 -sn 0 -n 4194304 -t 4 -path E:\burst\plots -mem 4G XPlotter_avx.exe -id 12878149936960097564 -sn 4194304 -n 4194304 -t 4 -path E:\burst\plots -mem 4G ...

@horego 262,144 is the size of one nonce. Based on the file sizes, Xplotter is generating the correct number of nonces, the GPU plot is off by one nonce.
-
@haitch tanks for your fast reply. 262,144 was a copy paste error ;)
but i'm not sure if the first or laste nonce is missing.
Does GPU plotter write the first "0" or is the last one "4194303" missing?
-
@horego I'm not sure - my GPU plotter plots are the correct size, don't know why yours would be off by one.
-
@horego sometimes GPU-plotter don't write last nonce in file (i saw it twice for my plots) - i'm used PlotsChecker for correct it (but only for unoptimized plots)
-
@Blago thanks.
My plots are already optimized. is there a way to fix it?
i tried to reproduce the missing nonce.
My configuration is RX 470 MSI. Win7 64 and gpuPlotGenerator-bin-win-x64-4.0.3.Within my test of parallel plotting a an increasing file getting larger then my gpu memory of 8GB i get the following result:
* stagger size of 4096 * starting nonce is 0. 4096 (1GB - OK) 8192 (2GB - OK) 12288 (3GB - OK) 16384 (4GB - Missing last nonce) 20480 (.... Missing last nonce) 24576 (.... Missing last nonce) 28672 (.... Missing last nonce)can anyone confirm this behavior? :-/

I think you're right, It seems that it can't find enough ram on your GPU :/
-
@horego Is the bug persistent across launches or is it random? Also, thanks for your tests, it'll help a lot to find the cause.
@Blago Same question for you as you experienced it.I'll do my best to correct this issue.
