@k06a good tip on using md5's
miner was throwing pool errors like the plot files were corrupt.

might try os x just for comparison
let me know if there is more i can provide to help you.

@damncourier can you give me command you used for plotting?
[email protected]:~/bc/plotter/mjminer-fix-optimize$ ./plot -k 6741243138549807594 -x 2 -s 6000000000 -n 12288 -t 4 Using AVX2 core. Total generation steps: 2 Creating plots for nonces 6000000000 to 6000012288 (3 GB) using 3072 MB memory and 4 threads Using ftruncate to expand file size to 3072GB 100.00% Percent done. 12976 nonces/minute, 0:00 left Finished plotting.
same command on mdcct (had enough ram no optimize needed at that size)
would it help to try different core (-x <n>)? (edit tried without change to md5)
@damncourier thanks for reporting! Just fixed bug. Try newest version.
$ sudo ./plot -k 6741243138549807594 -x 2 -d ./ -n 12288 -s 6000000000 -m 12288 -t 8 Using AVX2 core.

@k06a I will try this as soon as I can and let you know how it works
@k06a awesome, that produced correct file, thank you some much!
though now i have a feature request, feel free to disregard if it is a huge pain in the ass because a optimized cpu plotter for linux and os x is a huge contribution already.
a version or build option that uses sphlib shabal (or other none chip specific implementation) instead of mshabal assembly. i suppose this was what the dcct plotter used but i am unable to find a copy. this would remove 64 bit requirement (i have seen one request on discord for 32 bit linux plotter which was directed to the pocminer java version (never used this so dunno how it performs esp on 32 bit systems)) and should enable plotting on non x86 systems (a lot of interest on raspberry pi mining, don't know if plotting would be worth it but i have a pi3 and would be willing to try, also willing to trying on linux 32 and linux ppc). i know mshabal is used for performance reasons so another implementation would be slower.
as i have said i dunno how difficult this would be but it would provide native plotting to anything running linux (or unix-like) and able to compile c. just an idea that i had awhile ago.
anyway thanks so much!
@damncourier did you mean mshabal do not support 32bit?
@k06a sorry did my reading
from mshabal site
SSE2 instructions are available on all Intel processors from the Pentium 4 onward, and are a standard part of the 64-bit ABI.
i was trying on p3 with "make OS_32BIT=1" which doesn't remove sse2 instruction set
advice on make options or Makefile edits to remove sse4 source files completely?

The "original" dcct used a shabal implementation for 32bit which needs at least SSE2.
Today fixed macOS support for creepMiner (in
Is anyone interested in? I am using MacMini for mining (eats less than 85W)
Just finished an article about efficient plotting/mining on macOS/linux:

currently plotting on linux, working good so far, thanks!
