Hello !
I have some question regarding simulation times in Realflow and other software packages that using OpenCL acceleration
First of all , my GTX card shows me that it has 1.2 version of openCL .
Here on that site newest is 2.2 , is that a reason of not computing openCL on GPU ?
if I understand correctly , I can’t install 2.2 on GPU , its something that built inside it , right ?
When Using (GPU CUDA) redshift renderer for example , I know and see that it uses and loads GPU and surely times are amazing compared to CPU render .
- So , which Unit inside GPU in used when GPU computes on openCL ?
Some GPUs have 16bit/32bit/64bit performance info in their description specs .
for example brand NEW GP100 Quadro have :
FP64 Performance 5.2 TFLOPS
FP32 Performance 10.3 TFLOPS
FP16 Performance 20.7 TFLOPS
whereas , Quadro P4000 have only 32bit performance record:
FP32 Performance 5.3 TFLOPS
- Does it mean that P4000 will never compute 16 and 64 bit operations ?
3 Which one from those 3: 16/32/64 is used when computing using openCL on GPU ?
Short question: is there any reasong my GTX titan kepler , never gives me good results in GPU openCL ?
are GTXs capable of compute any of them 16/32/64 ? or only Quadros have that ability ?
