[ANN] Yet another GPU miner release! [YAC]

[superfry]

Great work on the miner hanzac. Getting 125kh/s on each of my 7770's and 110kh/s on my 5870

It seems that under this weird circumstance, the GPU miner should be released.
Here it is:
Prebuilt binary for windows 64:
http://sourceforge.net/projects/hnindev/files/yaminer-beta-winx64-2.zip
Source code:
http://sourceforge.net/projects/hnindev/files/yaminer-beta-src-2.zip
Win32 binary built by Thirtybird: https://mega.co.nz/#!e1YVDBYZ!YSzn40ba5ciOVUeJjIcQnFxbvr0JhdYwkzqempL_l8Y
(Package Status: MINOR UPDATE, correct the program name issue, upgrade to cgminer 3.2.1, If you have working installation, no need to update.)

It's based on the cgminer scrypt mining, but there's some difference, the lookup-gap=2 + thread-concurrency parameters are just used to for allocate the pad buffer. The intensity (I) means the global work size 2^I, it seems to be related to the Nfactor & GPU stream cores & GPU memory size. For the GCN GPUs, set the worksize to 256 and for the pre-GCN GPUs, set the worksize to 64.

Some typical command lines:
For 5950
yacminer --device 0 --scrypt --worksize 64 --lookup-gap 2 -I 11 --thread-concurrency 8192 -o <URL> -u <username> -p <password>
Currently can hash 190KH/s (Nfactor=9)

For 6750
yacminer --device 0 -
-scrypt --worksize 64 --lookup-gap 2 -I 10 --thread-concurrency 2816 -o <URL> -u <username> -p <password>
Currently can hash 47KH/s (Nfactor=9)

For 7950
Some correction
[Under Linux]
yacminer --device 0 --scrypt --worksize 256 --lookup-gap 2 -I 12 --thread-concurrency 32768 -o <URL> -u <username> -p <password>
Currently can hash 230KH/s (Nfactor=9)
[Under Windows]
yacminer --device 0 --scrypt --worksize 256 --lookup-gap 2 -I 11 --thread-concurrency 8192 -o <URL> -u <username> -p <password>
Currently can hash ???KH/s (Nfactor=9)

When running under linux, maybe you need to set these environment variables:

export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1

[Compilation under linux]
It's quite easy if you've already complied cgminer once (have all the other dependency libraries installed)
Run:

chmod +x ./configure
./configure --enable-scrypt
make install

Then, it will be installed into the application's dir (typical /usr/local/bin).

[Known issue]

• Because using the latest cgminer 3.2.0 code base, the network thread seems has slow reaction to submit hash & get a response at the beginning. After a while, it will become normal.
• AMD Graphics drivers prior to 12.X may not work, so recommend using newer drivers.

PS, my GPU miner is not quite fast comparing to some others, and it may not work for some other cards.

beta 1 was working but i cant get beta 2 (64bit) to work no matter what i set. was the -scrypt switch renamed?



yacminer --scrypt --worksize 64 --lookup-gap 2 -I 10 --thread-concurrency 2816

No the -scrypt switch not changed, because I think it's simple to use.

Can you lower the thread-concurrency or just fall back to beta 1. I can't tell the reason for this error.
Or maybe you can try reboot your PC to make a fresh start.

tried the 32bit version of beta 2 and its working fine with the same settings

figured out.

how to tweak for onecoin?

I found it needs some work for onecoin, onecoin uses salsa mixing not chacha mixing. Hash function is same both are keccak-512.

so is it feasible or maybe not worth the effort?

It's of course feasible. I just hope there're some one else can hack it if he's interested. Because my kernel is presented in a very clear way.
Just replace the chacha core with the salsa core, I think just that easy. After that, the Nfactor calculation needs to be changed also.

Because I don't have any onecoin position, I don't really have intention to do that.

i'll give it a crack, any pointers on where to look?

CL kernel file: scrypt-chacha.cl, find the function `static void chacha_core(uint4 state[4])`, trying to replace it with the function `static void salsa_core_basic(uint32_t state[16])` from file scrypt-jane\code\scrypt-jane-mix_salsa.h

scrypt.c, driver-opencl.c: GetNfactor(unsigned int nTimestamp), change to the function in onecoin.

I think basically these two places, other parameter to the scrypt hash seems to be the same like the rfactor, pfactor both are 0.

[barwizi]

thanks a lot, never messed with cgminer before, i'll tell you if i'm succesful and if i mine a few coin i'll throw some your way.

Cool, if you met some difficulty, let me know.

One last thing: the chacha_core in scrypt.c should also be replaced to salsa_core_basic.

ok i got the first part and third part done but i cant find the function  GetNfactor(unsigned int nTimestamp) in scrypt.c (onecoin)

It's in the main.cpp? Or search for it.

replace int64 with int64_t?

Add static modifier to these multiple definitions.
For example,
static void GetNfactor(...)

static int nChainStartTime ...
