I assume you are simulating resonators for ion traps with the eigenmode solver? I had quicker results optimizing with time-domain analysis (CST Microwave Studio), then switching to eigenmode to find the Q, than using frequency domain solver. The time-domain solver is easily spread across multiple GPU.

Hi madengr - Thanks for the comment. We're focused on solid-state qubits right now, not ion traps. Are you building your own GPU-based hardware for your simulations?

Nope, my workstation is a pre-built Tesla Whisper-station from Microway with two Nvidia K20. Also have a 4 node HP blade cluster dedicated for CST and Microwave Office (Axiem), with last generation Tesla GPUs. That 4 node cluster is expanded up to 32 nodes by convincing coworkers to install CST distributing computing solver server. That works really well for parametric sweeps and solvers that can't use GPU. It's sort of a cobbled together system, but it works well.

To what sort of problems are you employing eigenmode analysis, or just 3D EM in general?
