Unable to set block size/thread via command args

[calvintam236]

I have run xmr-stak-nvidia, and it gives me around 100H/s using this config: "threads" : 46, "blocks" : 4, "bfactor" : 12, "bsleep" : 0.
Just build the xmrig-nvidia on macOS, and with auto gpu config on GeForce GT 750M @ 925/2508 MHz, I could only get around 60H/s with it gets around 16 threads..
I couldn't find an option to set block size/thread via command args. Anything you can help improve this result?

GPU options can changed only config file, place config.json near xmrig executable, it will update config and you can change options.
Thank you.

Can you add such command args if I use just one GPU to mine? (I don't want to setup json file because it is more complicated to edit it in docker...)

@calvintam236 Can you suggest how command line options should named and how it use with multiple GPUs. Thank you.

@xmrig As the miner is going to merge CPU, AMD, and Nvidia versions in the future, I would suggest to add prefix to command args now. For Nvidia version, you can use --cuda.
For multiple GPUs setup, how about --cuda-threads 1000,2000 --cuda-blocks 1000,2000, which 1000 for gpu index 0, 2000 for gpu index 1. Same changes needed for --bfactor and --bsleep.
--max-gpu-threads will be replaced by the new thread option?

[xmrig]

I added new options:

• --cuda-devices List of CUDA devices to use, optional, if not specified all available devices will be used. Examples: --cuda-devices=0, --cuda-devices=0,2, etc.
• --cuda-launch=THREADSxBLOCKS Single option to specify threads and blocks, also can be comma separated. Other miners like ccminer and xmrMiner uses a launch option too.
• --bfactor, --bsleep not renamed, no equivalent for AMD, can be comma separated now.
• --max-gpu-threads deprecated, added --cuda-max-threads with equal functionality.

@xmrig Thank you for the update and great work.

While --bfactor and --bsleep don't have equivalent for AMD, no cuda prefix will make user think that these options are available for AMD as well.

Great job 👍 Now it's better
