[ANN][X11/X13] X11 (Darkcoin)/X13 (Marucoin) miner (based on sph-sgminer)

[jakecrow]

Won't start, win7 x64. Compiles, sees pools, then stops every time. Tried changing various parameters but same result every time.

[Remember remember the 5th of November]

I am looking into the issue.

I am looking into the issue.

Unfortunately, I haven't programming experience on windows.

I used sources from https://github.com/Atrides/sph-sgminer
Modded files
configure.in
ocl.{h,c}
driver-opencl.c
findnonce.h
miner.h
sgminer.c

I identified and corrected the problem  https://www.dropbox.com/s/skv74wv378h5qnl/sgminerx11.rar

The problem is the use of an unitialized variable as an index.

i.e    

Code:

if (gpus[i].kernel == KL_FUGUECOIN || gpus[i].kernel == KL_GROESTLCOIN || gpus[i].kernel == KL_TWECOIN) {
		sha256(pool->coinbase, pool->swork.cb_len, merkle_root);
	}

I applied a dirty fix by removing said IF sentence, simply because it's not needed for darkcoin.

i'm not a coder, but i'm curious what "sha256(pool->coinbase, pool->swork.cb_len, merkle_root);" does

This is not a my modification.
Maybe this code from cycle below...
Amazing, on Linux this works )

Windows build report: shares with diff -0.000 and speed jumps from 2.1 to 2.6 up and down, up and down.

[Amph]

displayed best share is wrong, is negative, diff also is at 0.000, something in the type of digits in the code

i've done some code in the past, but swork.cb_len, merkle_root i really don't know to what they refer

i'm not getting any speed increase (2.1 mh/s 280x & 7970) over the normal sph-sgminer with darkcoin kernel on windows 7 64 bit.

The 2% version speed was 3.1 mh/s for both cards

--gpu-threads 2 --thread-concurrency 8192 -I 15 --lookup-gap 2

you need intensity 15 for 3.15M/s, but the share value are all fucked up, they are negative, something wrong in the code

Did you select the x11mod kernel? Sounds like you omitted -k x11mod

[lasybear]

I'll be unavailable till 20:00GMT.

Please provide your settings and hashrates )

[SpeedDemon13]

I'm testing on older AMD cards, ie 5870,6950,6970,etc... Using -k x11mod, I=15, w=128, gpu thread=4, TC=8000, power tune=+20%, 880core/1350mem, lookup gap=2....

I'm getting 1.8~1.9mh/s on a HD6950 1GB, but the shares are -0.0000 and diff is 0.000/0.000 .

Original hash was 1.1~1.2.

It does seem the coding still needs some tweaking to work right.

Your version with settings : -k x11mod -I 15 --gpu-engine 1050 --gpu-memclock 1500 --thread-concurrency 8192 --lookup-gap 2 --gpu-powertune 20



2% version with settings: -I 20 -w 128 --gpu-engine 1050 --gpu-memclock 1500 --thread-concurrency 8128 --gpu-powertune 20



I have tried different parameters but nothing changes

You got that right.

Strange, everybody else is reporting higher hashrates. I know lasybear said intensity not to go over 15, but try setting it to 20 and test then.

[bbr]

-I 18 - 20 causes the AMD drivers to crash

[grendel25]

-I 18 - 20 causes the AMD drivers to crash

yep... they recommend nto going higher than -I 15

Hoping this gets tuned up a bit better.  Seems just a bit slower than the 2% fee scuzzball

It does hash and find work, but doesn't submit shares....

[ekoice]

looking foward for this...seems nice
