Brandon Tuomela	bda1070259	kernel: add psw kernel.	11 years ago
Noel Maersk	629f7b15e2	kernel/zuikkis: remove unneeded comments and change defines. I thought I've already fixed and committed this before. It probably got merged back in when I wasn't looking.	11 years ago
Noel Maersk	5f326d64f5	kernel: allow choosing Alexey Karimov's kernels. Am I the only one who gets a segfault?..	11 years ago
Noel Maersk	81337e0064	kernel: vanilla Alexey Karimov kernels (alexkarnew and alexkarold). alexkarnew: (for driver 13.4 and newer, and cgminer 3.3.1) alexkarold: (for older drivers than 13.4, and cgminer 3.3.1) https://litecointalk.org/index.php?topic=4082.0 > I was able to optimize the code of cgminer's scrypt.cl. > It gives 0-3% increase, depending on the drivers and hardware. > 1. Without optimization, when "CO" is used, every time > z+xzSIZE+yxSIZEzSIZE is calculated. > I have created "CO" variable, and made so that xSIZE is calculated only > once. Now, when "CO" is used, every time z+yxSIZEzSIZE is calculated. > In one case, variable y is incremented by 1 after 8 "CO" calculations. > I have created "CO_tmp" variable, where contains result of xSIZEzSIZE. > And after 8 "CO" calculations I add "CO_tmp" to "CO". > Now, when "CO" is used, every time only z is calculated.

I have replaced multiplication by 2 with bit rotation - it is faster. > For 7xxx cards you can try to set --thread-concurrency equal to (2^n + 1). > It may give a little more mining speed. > For example: 16385 (it is 2^14 + 1), 8193 (2^13 + 1), or 4097 (2^12 + 1). > I have almost no information, how it works on other series. > LMqRcHdwnZtTMH6c2kWoxSoKM5KySfaP5C	11 years ago
Gabriel A. Devenyi	a6ccc05e5f	Replace multiply by 2 (i*2) with left shift. This should be slightly faster. Can't use OpenCL rotate becase of bit carry overs	11 years ago
Noel Maersk	f796aa51ca	kernel/misc: change ckolivas.cl encoding to UTF-8.	11 years ago
Noel Maersk	afdc8b5ffb	kernel: zuikkis' vanilla kernel added. Changed encoding to UTF-8. Will not build with sgminer (fix in next commit). http://www.reddit.com/r/dogecoin/comments/1ui3bx/increase_such_hashrate_1_to_5_scrypt_tweaking/ceir5na > It is pretty much stock, except that I have removed all the #pragma > unrolls, and optimized the inner scrypt_core loop. #pragma unroll does > not give any speedup here. > The idea is to move the "if (j&1)" comparison to outside of the lookup > loops. Then, if j&1 happens to be zero, the V[z] and X[z] loops can be > combined to a single loop, which gives the speedup! > This loop and the salsa function are the most important places in the > entire source, it probably spends over 90% of time in here..

Noel Maersk	9d1db95a28	misc: move scrypt130511.cl kernel file to kernel/ckolivas.cl Prepare for more kernels. :) Get rid of the kernel date, since this fudges up commit history. Named after Con Kolivas, the most recent committer.	11 years ago
