- Added new option --cl-extragpumem with which you can let the OpenCL
miner know how much GPU memory you believe your system would need for
miscellaneous stuff like Windowing system rendering e.t.c. The default
is 350 MB.
- Added new option --curent-block with which you can let the miner know
the current block during the configuration phase and as such help him
provide a much more accurate calculation of how much GPU memory is
required.
- Added help(documentation) for some arguments that did not have one
- No need for many different functions to set each single option for the
miner. First we set all options and then we execute them. This way
--list-devices will give different results with --alow-opencl-cpu and
without it as it should.
- If the user has no GPU with sufficient memory we no longer default to
CPU. It's better to throw an error and let the user remove the
argument. It's easy to miss the defaulting to CPU log message.
By default now, CPU is not considered an OpenCL device.
Also added a new argument --allow-opencl-cpu, that would allow OpenCL to
include CPU devices if the user's openCL implementation caters for it.
- Removing --use-chunks argument. The decision to use chunks or not is
now made by the implementation, depending on
CL_DEVICE_MAX_MEM_ALLOC_SIZE
- Refactored the code a bit in ethash_cl_miner, abstracting out some of
the device iteration into its own functions.
By providing the --use-chunks argument dagChunks is set to 4. Default is
1 big chunk. Future improvement could be to provide arbitrary number of chunks.
