 |

Hi All,
I am considering to try Cuda-x86 for some project, and I would like to get some more information on it. So could anybody answer these questions?
- What warp size, and what compute capabiliy is used? Can I set it somehow?
- Is the warp size dependent on the CPU architecture?
- What compute capability is shown for CPUs? Can I change it somehow?
- How is the machine code vectorised? Are you using tricks similar to those described here for Intel OpenCL?

Warpsize is 1 and the CC is 99. No, you can not change these settings.

No.

CC is 99, and no you can't change it.

Classical compiler auto-vectorization using SSE/AVX.
