Noel Maersk	d7c8d1d300	core: change scantime/expiry to 10/30 from 30/120.	11 years ago
Noel Maersk	64fc8324b8	pools: initial implementation of pool state machines. moved enable_pool(), disable_pool() and other functions related to state. These could probably be factored out altogether. Pool state default is now "enabled" - it was previosly "disabled", but there was an unconditional function call to enable all pools in main() previously. It was factored out by joe's earlier commits, so not visible in this one.	11 years ago

Noel Maersk	22b78e91f6	tui: Refactor status line printing. Default pool name is now URL and port instead of "Pool N" (which is confusing). Status line displays user-defined name.	11 years ago

Noel Maersk	de08e71ea2	core: write xintensity and rawintensity to config, add vectors back as a hidden option; a little whitespace for readability.	11 years ago
Noel Maersk	dda62843fd	core: Add -v as an shorthand for --verbose.	11 years ago
Noel Maersk	e8978db55f	kernel: slight refactor, add warnings about new kernels, and known limitations of zuikkis. Limitations of alexkar* kernels are not known to me. Closes https://github.com/veox/sgminer/issues/28	11 years ago

Noel Maersk	abf1b940b5	doc: update README.md to point to KERNEL.md	11 years ago
Noel Maersk	5f795be64a	core: use kernel name defines now that version date is not in the filenames. Ideally, even this should not be needed, and specifying a kernel name string should search for the appropriate file in kernel-path.	11 years ago

Noel Maersk	e9af2109c3	doc: change bog reporting address.	11 years ago

Noel Maersk	d04a8d174b	tui: display line getting off-screen on narrow terminals.	11 years ago
Martin Danielsen	d11df698d1	--rawintensity option, by request of Dead2. This setting allows to set the GPU intensity value directly without any modifiers, it does not get any more raw than this! Look at the xintensity description raw for examples of regular intensity values. You can also set this value through the ncurses interface by pressing: G -> A -> select device id -> enter value. Minor xintensity code cleanup as well. Conflicts: driver-opencl.c miner.h sgminer.c	11 years ago
Martin Danielsen	967c757cdf	Cleaned a few messages up after pool naming feature.	11 years ago
Martin Danielsen	cb174d433a	Failover pool switching back delay is now configurable. --failover-switch-delay sets the delay in seconds before switching back to a failed pool, default is 60 seconds.	11 years ago
Noel Maersk	35a23942b1	kernel: fix alexkar* kernel crashes due to missing case in switch. Fixes https://github.com/veox/sgminer/issues/27	11 years ago
Noel Maersk	45bf2f2335	doc: Add debug compilation instructions.	11 years ago
Noel Maersk	2f1fafedb9	doc: skeleton KERNEL documentation. On how to submit new kernels. This should allow a broad community review.	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	4de27856af	misc: add ozbenh and gdevenyi to AUTHORS.md.	11 years ago

Noel Maersk	9545c143e8	Merge pull request #25 from gdevenyi/kernels Replace multiply by 2 (i*2) with left shift.	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.

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	7950c10374	kernel: integrate Zuikkis' kernel, selectable with `--kernel=zuikkis`. Kernel ckolivas is still the default. Needs documentation, too. https://github.com/veox/sgminer/issues/4	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.
