Hi, Since you mentioned the GPUs on your desktop, I assume it's about the GPU-based Chrono DEM tools. You should be able to simply run a couple of them on parallel, but truthfully, about the throughput impact, we never tested.
My guess would be that on consumer GPUs, running 2 or 3 instances together may slightly improve the throughput. On data center GPUs, running a small number of instances may moderately improve the throughput. Again, this is a guess and I am nore than interested in knowing your findings should you test it out. Thank you, Ruochun On Thu, May 30, 2024, 7:16 AM Jared Long-Fox <[email protected]> wrote: > Hello all! I am working on a project in which I need to calibrate a model > to experimental data.
