Hi Jean-Luc,
Thank you for the kind wishes. Those are some great questions! We are definitely running HFSS, and we've made some small investments in traditional HPC hardware. Our primary use case thus far has been Eigenmode solver, which doesn't parallelize well. We're figuring out how use Driven solver a little more - the HPC packs provides a real boost in that case. We're excited to be expanding the eco-system of companies doing groundbreaking QC work beyond the standard list of big defense contractors :)
- madengr 12y agoI 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.
- crigetti 12y agoHi 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?
- madengr 12y agoNope, 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?
