Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining initially

cgminer must be parsing the output buffer differently from poclbm (see SETFOUND macro in its kernels), otherwise looks good, at a glance. Please also note the kernel only returns diff 1 shares, for pool you are going to need to either hardcode the target or pass it to kernel.

Yes, cgminer parses it differently. I added this

Code:

// output[OUTPUT_SIZE] = output[nonce & OUTPUT_MASK] = nonce;
#define FOUND (0x0F)
#define SETFOUND(Xnonce) output[output[FOUND]++] = Xnonce

SETFOUND(nonce);

to your kernel and it should work.
Unfortunately it never reaches this code (on Geforce GT 650) and I don't know why...

You can try a lower diff (uncomment the '& 0xc0ffffff' for example) and see what happens. You can also use printf() in the kernel for debugging if your SDK is at least OpenCL 1.1 compliant.

I'm just wondering how you could compile the kernel for poclbm in python that you showed, to cgminer.
I've looked at the others kernel in cgminer like diablo or phatk, this doesn't look the same at all.
Any explanation would be nice

thanks
