I am using NVIDIA Quadro K2000 GPU. I ran
deviceQuery.exe, the results of which are below. It says that I have only 2 SM units. I am not sure if I really have only 2 SMs or some of my SMs are disabled as mentioned at the third comment at this SO question.
I also saw that the number of SP are 192 per SM. May be there is some way to enable more SM and then the number of SP per SM will decreased.
Update: The reason I am asking is the fact that I want to make my GPU processing efficient. I have an image of 1080 x 1920 which I have divided into three segments. I am transferring these segments H2D, processing and transferring D2H asynchronously. Therefore, I want to choose such a dimension of blocks and number of threads per block that can efficiently utilize the hardware configuration of my GPU. Furthermore, I am still confused that a GPU having more than 2 SMs (let's say 8 SMs) but less number of SPs per SM (384/8 = 48 SP per SM) would perform same to a GPU having 2 SMs and 192 SPs per SM ? I mean, is it the total number of available SPs which matters?
