GPU for Ansys FLUENT

TAGGED: ,

      Hi there,

      I have some questions about the GPU application in Ansys FLUENT, would be thankful if somebody helps

      1)What is the GPU-supported list for 2023 r2 (which uses a fully GPU-based solver)

      2) In some Ansys versions a GPU like RTX 4000 and RTX 6000 is supported and tested. Does that mean RTX  5000 is %100 supported?

      3) If a GPU supported in older versions like the Quadro M series, or the K series, still supported in the newer versions? (fully or partially)? 

      as I see every GPU support list is issued for every version only several GPUs are mentioned, so can we assume for somebody who is using 2021R2 that all the GPUs in the previous supported lists in official PDFs up to at least 2021R2 are still supported and can be used in the solving process in parallel?

      Thanks,

      Amir

      Also as question 4,

      is Quadro k6000 supported in Ansys FLUENT 2021R2 (in parallel with CPU) and 2023R2 (for Native Multi-GPU Solver)

      Supported cards for the GPU solver(s) are covered in the various documents here https://www.ansys.com/it-solutions/platform-support   We cannot comment further on that. Remember that the gpu assist and pure gpu solvers are not the same thing.

        Well, thank you for the link.

        yes, I know the GPU assist and pure GPU solvers are not the same thing, my first question was which GPU be used for pure GPU solvers in your new Ansys version?

        for the second question, do you mean you can not confirm if the higher and lower model from a GPU with the same architecture is supported (as GPU assist solver), and the middle is well supported?

        for the third question, it is possible the flagship of Kepler architecture is not supported in the new model even as a GPU assist solver anymore?

      For the first question please read the document. Similarly the second and probably third. We can ONLY say that the tested cards will work (or not). Other cards haven't been tested so we can't comment.
