  1. Support multiple GPUs (split mode) on SYCL backend.
    split mode: [none, layer] supported; [row] not supported, it's on developing.

  2. Unify the GPU setting as Cublas backend:

  • support set main gpu by: --main-gpu
  • support detecting all GPUs with level-zero and same top Max compute units.
  • remove use GGML_SYCL_DEVICE to set main gpu.
  1. format to show the device list, like:
found 6 SYCL devices:
|ID| Name                                        |compute capability|Max compute units|Max work group|Max sub group|Global mem size|

detect 2 SYCL GPUs: [0,5] with Max compute units:512
  1. Support OPs:
  • hardsigmoid
  • hardswish
  • pool2d
  1. Use device index to set/get GPU data internal data.
    same as cubals backend.
  2. Use device ID to set/get GPU device info.

I think this can be removed now, device_list does not seem to be used anymore.

Note that -mg is ignored with -sm layer, which is the default, so passing it here does nothing.
