Eigen with SYCL for tflite

SYCL development
1

Currently in our code in tflite we use the eigen library for our custom kernels for the Android devices. If we compile our library with EIGEN_USE_SYCL=1 will there be any speed increase using:

  cl::sycl::gpu_selector selector;
  Eigen::QueueInterface queue(selector);
  Eigen::SyclDevice device(&queue);

instead of what we currently do:

  const EigenForTFLite::ThreadPoolDevice* device =
      eigen_support::GetThreadPoolDevice(context);

Hi @hamlatzis,

I think it’s unlikely to work as you would need a SYCL implementation which worked on the Android devices as well as some compatible backend for the SYCL implementation to target, and I’m not aware of any working right now.
