Hi In the following code, I would like to collect the SM IDs that have executed the kernel. The kernel is a simple addition one and I have written this code: __device__ uint get_smid(void) { uint ret; asm("mov.u32 %0, %smid;" : "=r"(ret) ); return ret; } __global__ void simpleAdd(fl…

That is no surprise, is it? nsmid is simply an upper bound for smid. they are not equivalent. This code will print a histogram of used sm ids. #include <iostream> #include <map> __device__ int get_smid(void) { int ret; asm("mov.u32 %0, %smid;" : "=r"(ret) ); return ret; } __global__…

OK Thank you very much.
I also found an answer to the first question with an example in this page

smid.cu

#include <stdio.h>

#define DEVICE_INTRINSIC_QUALIFIERS   __device__ __forceinline__

DEVICE_INTRINSIC_QUALIFIERS
