Topic: [ANN] Yet another GPU miner release! [YAC] - page 16. (Read 53345 times)
Great work on the updated kernel, doubled the hashrate on my 5870 (110Kh/s to 235Kh/s) and increased my 7770's from 125Kh/s to 153Kh/s
Where is yacminer.c being generated then? i tried the --with-scrypt arg to configure in case that might cause configure to create that file but there is still no such file.
There is no yacminer.c; check cgminer.c
echo " CCLD " yacminer;gcc -g -O2 -lpthread -o yacminer cgminer-cgminer.o cgminer-util.o cgminer-sha2.o cgminer-api.o cgminer-logging.o cgminer-driver-opencl.o cgminer-ocl.o cgminer-findnonce.o cgminer-adl.o -lcurl -ljansson -lpthread -lm lib/libgnu.a ccan/libccan.a -lncurses -lpthread

Update. My 6850 is maxing out on Linux at 133Kh/s with:
thread-concurrency and shaders make no difference, except their cap is 8180 and 960. Also above I 15 the gains are very small.
Code:
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
-I 18 -w 128 --lookup-gap 2 -g 1

A (sort of) off topic question for those in the know...
This yacminer seems to work great with my 7870 LE EZ tahiti based(aka 7930) where as its terrible with mining ltc or anything scrypt. I have it up to 270khash now with yacminer compared to the 230 posted for a 7950 in the op. Would I would like to know is what makes this perform so much better than mining scrypt with cgminer for a 7870 tahiti gpu like mine? Also, is it somehow possible to make a tweaked yacminer to mine ltc or other scrypt based coins? I know this sounds odd to those that are unfamiliar with the card. The card is absolute trash at scrypt but its great at sha and it also seems to be just as good as a 7950 with yacminer. If yacminer could be somehow tweaked to mine scrypt so the 7870 tahitis potential could be unlocked thatd be most awesome.

I guess thats good

yacminer --scrypt --worksize 256 -g 2 --lookup-gap 4 -I 11 --thread-concurrency 17000
really like this miner, thanks so much for all the hard work
Alright, I transferred more features from the normal scrypt kernel and got even more speed out of the scrypt-chacha kernel.
Notable changes:
- Added support for CONCURRENT_THREADS
- Fixed support for LOOKUP_GAP when it's not a power of 2
scrypt-chacha-v3.cl
https://mega.co.nz/#!cxUUmRga!I3ttCwVJIjt9g14sXW33FhJZLhtTqyWtcGQ2vFI8vsY
How to use:
1. Download the new kernel file.
2. Rename to scrypt-chacha.cl.
3. Copy to your GPU miner folder.
4. Delete any .bin files.
5. Restart your miner.
6. Look up settings from the Litecoin wiki.
The tuning parameters are now compatible with the scrypt kernel. You can look up optimal settings on the Litecoin wiki:

Edit: see below.
using your cl file it did not change speeds for me. using nvidia card. 2 k/h slower. but to get optimal settings I had to bump -I up by 1 and double work-size
I added support for LOOKUP_GAP to the scrypt-chacha kernel. This allows higher intensities and higher efficiency. I'm getting 35% more khashes/s out of my 7790.

nice improvement, was able to get i 11 and another 6kh out of my 560ti, now 42 kh vs 36kh on the old version and 22kh on an i5
couldnt find the exact thread-concurrency but after the gfx driver crashing 10 times i gave up. its somewhere between 2048 and 2064

This is great! Thanks!
Wow, my 5770 went from 56kH to 87kH! 
Thanks!
Thanks!
You are right, intensity 13 works! And I have received a bit of a boost on the 7970, awesome job thanks man! 
Keep up the good work
Keep up the good work If your 7970 has enough memory, you can try even higher intensities. You just need to double thread concurrency with each increase of intensity.
Try something like this:
Code:
./yacmine --scrypt -w 256 --lookup-gap 2 -I 14 --thread-concurrency 16416 -g 1
This needs more than 1 GB of RAM.
Or even higher:
Code:
./yacmine --scrypt -w 256 --lookup-gap 2 -I 15 --thread-concurrency 32832 -g 1
Intensity 15 needs more than 2 GB of RAM.
I know this is thread about developing cgminer but maybe someone skilled enough can implement scrypt-jane to stratum mining server as pushpool has terrible performance for lots of connections

maybe the older kernel was still in my cache, or something. after a reboot it does work now

Keep up the good work 200 YAC for you!
Try a lower intensity if it's freezing. Also make sure you replaced scrypt-chacha.cl and that the .bin files are gone. The settings I posted will crash your GPU with the old kernel.
