From Anandtech:
"For that reason I wouldn’t be too surprised if we a Tesla card using it aimed at FP32 users such the oil & gas industry – something NVIDIA has done once before with the Tesla K10 – but you won’t be seeing GM200 in the successor to Tesla K40."
Tesla K40 is GK110 based.
Nooooooo! That's precisely where the 1/32 ratio comes from! The FP64 ALU units are responsible for... DP performance! If you have less of them enabled, you have less DP performance!
What do you think 1:32 ratio means??? It means that there is 1 FP64 unit per 32 FP32 units! A ratio of 1:3 means there is 1 FP64 unit per 3 FP32 units! That's what it means. Nothing about scheduling!
