Greetings,


I'm trying to optimize a machine to run RapidCFD, and would like to know more opinions about what GPU to buy for it. I think I've read through most of the posts in this forum that mention RapidCFD at this point, and there is quite the mixture of Teslas, Titans, and Quadros being used on that code, but I haven't seen any discussions on the best setup for it.


RapidCFD and their GitHub mention the Tesla K20. I'm already basically aware of the differences between "workstation" cards Teslas and Quadros vs. "gaming" cards like Titans and GeForces (other than just the raw TFLOPS). I'm more wondering about other practical considerations. Will a bigger card always provide better results? How cheap can we make the CPU since RapidCFD runs on GPU? Multiple smaller GPUs vs. one bigger GPU? What would be a good "reference machine" (incl. motherboard, ram, etc.) for this?



Just FYI, I am a professional engineer looking to apply CFD to drone design. Maybe there's nothing more to say than the stations people have mentioned in this thread, but if there is more to say, please post it here. Thank you.
