No GPU activities in profiling with nvprof
问题 I run nvprof.exe on the function that initialize data, calls three kernels and free's data. All profiled as it should and I got result like this: ==7956== Profiling application: .\a.exe ==7956== Profiling result: GPU activities: 52.34% 25.375us 1 25.375us 25.375us 25.375us th_single_row_add(float*, float*, float*) 43.57% 21.120us 1 21.120us 21.120us 21.120us th_single_col_add(float*, float*, float*) 4.09% 1.9840us 1 1.9840us 1.9840us 1.9840us th_single_elem_add(float*, float*, float*) API
