Re: Official DiabloMiner GPU Miner Thread (now with Long Poll and BFI

I'm having a look at your code because i would like to understand how a miner works.
I have a few questions.
Where i can find how is stored the data contained in the work sent to the miner from the server ?
Also could you explain a little bit in few words what happens in lines of code between 888 and 944?
Here:

Code:

bufferIndex = (bufferIndex == 0) ? 1 : 0;

   workSizeTemp.put(0, workSize);
   currentWork.update(workSizeTemp.get(0) * loops * vectors);

   System.arraycopy(currentWork.midstate, 0, midstate2, 0, 8);

   sharound(midstate2, 0, 1, 2, 3, 4, 5, 6, 7, currentWork.data[16], 0x428A2F98);
   sharound(midstate2, 7, 0, 1, 2, 3, 4, 5, 6, currentWork.data[17], 0x71374491);
   sharound(midstate2, 6, 7, 0, 1, 2, 3, 4, 5, currentWork.data[18], 0xB5C0FBCF);

   int fW0 = currentWork.data[16] + (rot(currentWork.data[17], 7) ^ rot(currentWork.data[17], 18) ^
   (currentWork.data[17] >>> 3));
   int fW1 = currentWork.data[17] + (rot(currentWork.data[18], 7) ^ rot(currentWork.data[18], 18) ^
   (currentWork.data[18] >>> 3)) + 0x01100000;
   int fW2 = currentWork.data[18] + (rot(fW0, 17) ^ rot(fW0, 19) ^ (fW0 >>> 10));
   int fW3 = 0x11002000 + (rot(fW1, 17) ^ rot(fW1, 19) ^ (fW1 >>> 10));
   int fW15 = 0x00000280 + (rot(fW0, 7) ^ rot(fW0, 18) ^ (fW0 >>> 3));
   int fW01r = fW0 + (rot(fW1, 7) ^ rot(fW1, 18) ^ (fW1 >>> 3));

   int fcty_e = currentWork.midstate[4] + (rot(midstate2[1], 6) ^ rot(midstate2[1], 11) ^ rot(midstate2[1], 25)) +
   (midstate2[3] ^ (midstate2[1] & (midstate2[2] ^ midstate2[3]))) + 0xe9b5dba5;
   int fcty_e2 = (rot(midstate2[5], 2) ^ rot(midstate2[5], 13) ^ rot(midstate2[5], 22)) + ((midstate2[5] & midstate2[6]) |
   (midstate2[7] & (midstate2[5] | midstate2[6])));

   int fcty_e_plus_e2 = fcty_e + fcty_e2;
   int fcty_e_plus_state0 = fcty_e + currentWork.midstate[0];

I also noticed that i get 'Spurious CL_INVALID_KERNEL_ARGS error, ignoring' when running with -d enabled, what could it be ?
Thanks for the patience Cheesy
