Hi,

Before changing to OpenCl, I could not perform operations with many edges (maybe around thousands) since it would fail the execution (typically at this sort of lines that you indicate).

Then, I installed OpenCL (for windows: [OpenCl in Windows 10](https://bempp.discourse.group/t/opencl-in-windows-10/165)), and now I can run with many more adges and in faster execution time.

Regards,

Marc
