Noel Maersk	5f326d64f5	kernel: allow choosing Alexey Karimov's kernels. Am I the only one who gets a segfault?..	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	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
Noel Maersk	99fa25c27f	core: don't use magic numbers to set xintensity.	11 years ago
Noel Maersk	463668b878	core: initial implementation of user-settable xintensity. Has a bug. Changing `intensity` and to it from `xintensity` works fine. Changing `xintensity` sometimes fails to enqueue kernel. For example, starting with --xintensity=128 (on a 5850) and then changing to 64, 42, or 100 is reliable. However, changing to 127 is not, and produces [04:13:01] Error -54: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel) [04:13:01] GPU 0 failure, disabling! Manually enabling the disabled GPU is successful, but the GPU no longer submits shares. This might be a hardware limitation.	11 years ago
Noel Maersk	9d0b7f9658	core: Accidentally left a part of a previously non-merged commit (thread display). IMO threads don't change dynamically, so they shouldn't be displayed in the main window, but in "GPU settings" menu instead.	11 years ago
Martin Danielsen	7aeae40af2	EXPERIMENTAL: A new way of setting intensity; introducing xintensity! All of this is credited to ArGee of RGMiner, he did the initial ground work for this setting. This new setting allows for a much finer grained intensity setting and also opens up for dual gpu threads on devices not previously able to. Note: make sure to use lower thread-concurrency values when you increase cpu threads. Intensity is currently used to spawn GPU threads as a simple 2^value setting. I:13 = 8192 threads I:15 = 32768 threads I:17 = 131072 threads I:18 = 262144 threads I:19 = 524288 threads I:20 = 1048576 threads Notice how the higher settings increase thread count tremendously. Now enter the xintensity setting (Yes, I am a genius with my naming convention!). It is simply a shader multiplier, obviously based on the amount of shaders you got on a card, this should allow the same value to scale with different card models. 6970 with 1536 shaders: xI:64 = 98304 threads R9 280X with 2048 shaders: xI:64 = 131072 threads R9 290 with 2560 shaders: xI:64 = 180224 threads R9 290X with 2816 shaders: xI:64 = 163840 threads 6970 with 1536 shaders: xI:300 = 460800 threads R9 280X with 2048 shaders: xI:300 = 614400 threads R9 290 with 2560 shaders: xI:300 = 768000 threads R9 290X with 2816 shaders: xI:300 = 844800 threads It's now much easier to control thread intensity and it potentially allows for a uniform way of setting the intensity on your system. I'm very interested in constructive feedback, as I do not have access to a lot of different card models. This change has been tested on 6970, R9 290, R9 290X - all with equal or a little better speeds than regular intensity setting after a little tuning, but your mileage may vary. Don't fret it, if this doesn't work for you, the regular intensity setting is still available. Conflicts: driver-opencl.c sgminer.c	11 years ago

Martin Danielsen	31123de410	-g or --gpu-threads now support comma separated values, yaaay! It is exactly what it says, now you can finally put that Frankenrig configuration in one file. The parameter follows the same design as gpu-engine and gpu-memclock.	11 years ago
Noel Maersk	d53b329f18	core: Revert printing threads for every GPU, this setting is not modifiable at run-time.	11 years ago
Martin Danielsen	89663c7e94	Display reject percentage instead of absolute accepted/rejected values Changed GPU status line from "A:xxxxx R:xxx" to "R:0.0%". It shows (rejected/(accepted+rejected))*100, which is the percentage of rejections for a GPU. Total accepted and rejected in top status is unchanged. GPU status lines now show both threads and intensity.	11 years ago

Noel Maersk	533f16aeb1	Increase MAX_INTENSITY to 42. Untested, since I do not have the hardware that supports such high a setting. Requested by yellowz06 on Litecoin Forum: https://forum.litecoin.net/index.php/topic,6925.msg54952.html#msg54952	11 years ago
