[ANN][YAC] Yacminer GPU miner for Yacoin

[CaptainBeck]

I'm not sure this works rite.

I've got a 7870 that i'm trying to run this on and its getting around 4khs but never finds an accept.

Code:

yacminer --gpu-platform 1 --scrypt - I 10 -g 2 -d 0 -w 256 --thread-concurrency 8192

I now the pool is setup right because i;ve got cuda cards that are finding shares and a cpus.

Lower your intensity until you stop getting HW errors

Although not Yacminer related, but i cant seem to get my YaCoin Wallet to sync at all, tried on two different machines and with no firewalls.

It still wont connect to anything.

Code:

rpcuser=******
rpcpassword=******
rpcallowip=127.0.0.1
rpcport=3339
port=7688
daemon=1
server=1
addnode=78.21.9.49
addnode=76.115.8.101
addnode=124.149.56.205
addnode=178.130.36.81
addnode=82.6.77.126
addnode=106.187.55.212
addnode=81.202.104.33
addnode=84.200.17.178
addnode=88.204.169.242

Is the yacoin.conf i put in the roaming data folder.

Hey!
I dont know why, but that dont work with my GPU..
I have AMD 6780 and i can normaly mine in scrypt and sha256 too.. but these yacminer dont work for me.
When i mine with cgminer all my shares is rejected, and when i mine with yacminer i have lot of HW errors and no one accepted.
I have soon tested many options, and changed soon the new scrypt-chacha.cl file what 20853 byte is is.. but nothing is better.
I have tested both 64 bit and 32 bit version of the application.
What i use:
yacminer --scrypt -o http://yac.ltcoin.net:5555 -u ifa88 -p x

Any ideas?

your settings are likely too harsh - intensity should be around 8, and you need to specify thread-concurrency based on the amount of memory your graphics card has.  Tuning for YACoin is a fidely process, but this is what I have for my 5870, hopefully you can find decent settings from here.

Code:

yacminer --scrypt --worksize 64 --lookup-gap 2 -I 8 --thread-concurrency 8192

Just thought I would post this here - I've done a little tweaking to YACMiner and have compiled Windows x86 binaries.  This update changes the display a bit so that it counts accepted/rejected shares*difficulty and the Utility(U) score is based on this submitted share size as well to make comparing different configurations easier especially if you're on a vardiff pool.  I also added a Found Blocks (FB) field into the display - it increments when you find a share larger than the block size, and as far as I can tell it will still increment even if the share is not accepted due to hardware error (still looking into whether this can be avoided).

Thanks for the new version!
Could you maybe update the cgminer backend to a slightly newer version?
I simply don't get any visible output if I don't use -T. My cmd window is simply black. I once had that with an old cgminer too, a newer version fixed that (if I remember correctly).
Using Windows 8.1 x64 on this machine with a Radeon 5870m and 13.12 drivers.

Do me a favor, and try the --no-adl switch without the -T.  I had this on a laptop, and I recently saw someone made a fix for that, and I'm curious if that's the same problem you're encountering.

It's unlikely I'll update to a newer version of cgminer, because the majority of the changes that have been made have been to support ASIC's and ASIC drivers.

tuning for scrypt-chacha is a process.  You keep trying settings until they get better.  I'm surprised to see a HW error at I=8 though.  I would wager you haven't allocated enough memory.  Up the thread-concurrency until you've allocated as much memory as you can - Use GPU-Z to see how much is allocated.  Yacminer will tell you if you've tried to allocate too much.  When playing with a new card, I will set the thread concurreny way too high for the card and let it tell me what the max is.  I start from that number and work my way down until the card starts hashing.

Other things to try once you get that sorted out : G 2, worksize 128 and 256, overclocking.

First sucess:D
This is the option:

Code:

setx DISPLAY=:0
setx GPU_MAX_ALLOC_PERCENT=100
setx GPU_USE_SYNC_OBJECTS=1
yacminer --scrypt -o http://yac.ltcoin.net:5555 -u ifa88 -p x --thread-concurrency 6720 --lookup-gap 2 --worksize 256 --shaders 1120

When i try the 9 intensity, i get only hw errors.
When i use normal script then i have 200-250khash speed with intensity 20 without HW error.

Your card is a 1GB card based on the 1 picture, but only 486 MB is being allocated.  I would double your thread-concurrency and see where the memory usage is.  The more memory allocated, the faster it can be pushed and not overwrite memory cells that are in use by ongoing calculations, which is what causes the HW errors.

[patoberli]

Thanks, --no-adl works!

[Thirtybird]

Implemented the ADL fix as requested, fixed the issue with found blocks being incremented even with an invalid nonce, and a couple other little things

trying to mine with Sapphire Radeon 7950 but the yacminer doesn't show any accepted/rejected and it also shows HW with increasing numbers.
Somebody has good config for the miner to use with 7950?

There seems to be a problem with yacminer, I also get hardware errors. I tried to lower the intensity as low as 10, but still get hardware errors. And the speed is 1.6 kh/s which is not really useful for anything.

Using an R9 290

Any users here with solutions?

Thirtybird and other developers, could it be there is something in the miner that lets it work with only some cards? or the SDK needs updating?

The highest intensity I have been able to go has been 9 - and that still generates some HW errors.   Low hash rates are to be expected, you just need to figure out which settings are best for your card.  If you buy me an R9 290, I'll send you the best configuration for it

[Coin.millionair]

Is anyone out there who are  succesfully mine YACOIN with cgminer
Is it possible to mine it with GPU or only with CPU ?

i cant get cpuminer nor cgminer to work.
Always get error message "no reply by empty server"
or
if hashes, then all package rejected, 0 accepted.


Help or advice (proper settings) needed !!!

Thank You in advance for ur replies...
