wow, that got  it to compile thanks....but hehehe it refuses to play ball

... have changed the anything about the kernel parameters? Did you just download the yaminer-beta-src-2.zip and modify?

Yeah i used he one you uploaded

[hanzac]

It's not easy task 
You can try rollback the changes and compile and run, to see if have these errors.
Then add the set of changes, one by one, when adding each one, compile & run, to see if have these errors.

This will help you identify which step you make a mistake. Then trying to correct it. I'll go sleep now ...

thank you, goodnight

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.

scrypt-chacha.cl with support for LOOKUP_GAP
https://mega.co.nz/#!l0sixSoQ!Xzzic2-GwMfGu3kefL8A1HmZuC8fuE3tlKiHdVO8-7M

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. Adjust intensity.

My miner settings for a 7790:

Code:

./yacmine --scrypt -w 256 --lookup-gap 2 -I 13 --thread-concurrency 8208 -g 1

[Eli0t]

i thought the original already had lookup gap

[mikaelh]

i thought the original already had lookup gap

No, there was no actual support for it in the OpenCL code.

My miner settings for a 7790:

Code:

./yacmine --scrypt -w 256 --lookup-gap 2 -I 13 --thread-concurrency 8208 -g 1

I tried this exactly but it freezes my computer

[mikaelh]

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.

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

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

200 YAC for you!

[feeleep]

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

[mikaelh]

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

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.

Wow, my 5770 went from 56kH to 87kH!  
Thanks!

sorry for being suspicious i didnt realise it was just a cl file

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

yacminer --scrypt --worksize 128 --lookup-gap 1 -I 11 --thread-concurrency 2064

[wetroof]

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

[bitdwarf]

Edit: see below.

[mikaelh]

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:

My settings for a 7790:

Code:

./yacminer --scrypt -w 128 --lookup-gap 2 -I 17 --thread-concurrency 8000 -g 1

really like this miner, thanks so much for all the hard work
