Dear Lumerical team (& forum members),
since there seems to be no information available in any knowledge base or in the forum, we wanted to ask if Lumerical (at least version 2023R2 and later) makes use of AVX-512 instructions or only AVX2 instructions? With the newest generation of workstation CPUs slowly incorporating AVX-512, it would be important to know if any benefits of this advanced instruction set are leveraged, or if processors with (only) AVX2 support are essentially equally powerful for FDTD and RCWA simulations.
In addition, do we understand it correctly that for academic licenses 32 cores are the limit per license, or actually 32 threads?

Ansys Lumerical support AVX instructions though that’s not too critical for our performance at the moment. More important is memory bandwidth.

1 Solve license = running up to 32 logical processors/threads on your local computer with hyperthreading. Otherwise, without hyperthreading, you will be running on the physical cores of the local machine.

Hope this helps.
