Hi,
I have managed to install OpenCL in Windows 10 and Bempp detecting it on Jupyter Python.
I installed the following drivers:
Intel® CPU Runtime for OpenCL™ Applications 18.1 for Windows* OS (64bit or 32bit)
From: OpenCL™ Runtimes for Intel® Processors
The computation, provided there is enough RAM (I have 32 GB) is extremely faster than Numba.
