Gtx 260m "canMapHostMemory = 0"

Hey guys, I’m trying to use some pinned memory and zero-transfer memory in my application, but the problem is that when I try to check the canMapHostMemory flag it is false, but the gpu I’m using is kind of good and should support this feature, don’t it?

So what can I be doing wrong?

GPU: Gtx 260m

I am trying to do anything to let faster the transfering of data between the host and the device, do you have any kind of sugestion? My problem doesn’t let me use the async way (at least if I didn’t sync it after the finish of the execution).

Thank you, Felipe Lopes.

Despite the suggestive model number, GTX260M is a compute capability 1.1 device. (Appendix A of the CUDA programming guide.)
