Hi,

Just wanted to check if the GeForce GTX 285 is compute capability 1.3?

thanks,

Yes.

I know the answer should be yes… but running the openclprofiler (with cudaprofiler should be the same) i got this output analyzing occupancy (the card is an ASUS ENGTX285):

Active threads per SM = 648 : 768

Occupancy = 1 ( 24 / 24 )

Achieved occupancy = 1 (on 30 SMs)

Shouldn’t it be 1024 threads per SM instead of 768 and 32 warps per SM instead of 24, for compute capability 1.3?
