Ansys Fluent GPU speed test - full demo

[@chrisb7161]

I’m not sure if it’s that much faster in double precision without a high end Tesla A100 or H100 that actually has the TFLOPS of FP64. Yes in single precision it is lightning fast. I would LOVE to see them get the multiphase solver ported next!

Just tested it on our machine. Double precision is also blazingly fast on our RTX4050. Maybe 60% slower than single precision and still way faster than CPU.

@@OzenEngineeringSimulation please review 4050 vs i9 vs ryzen 9 or what you have or old tesla k80 that has double precision

[@tea-hash-sea]

​@@OzenEngineeringSimulation So, do you confirm that Fluent can run with Geforce cards ? (both native GPU solver and acceleration of CPU solver ?)

Hi, I got myself a quadro rtx a2000 and the utilisation is 0% on simple method, I have a r9 3950x 16 cores with 64gb ram, any idea why it doesn't work?

Your probably not making sure to select the GPU to run calculations. There are videos on YT to show you how to make sure they are working

hahaha ı hope he know it. @@tomasmartins3541
