nsys可以观测整体kernel的耗时,但有时候程序逻辑很多,我们只想观测指定的kernel,难免被其他kernel影响观测,而且我们很多时候也需要统计指定的kernel耗时信息,如平均时间,中位数,分布等等,这时可以使用CudaEvent。主要使用如下几个API: cudaEventCreate() cudaEventRecord() cudaEventSynchronize()cudaEventElapsedTime() cuda...

Hi, I am trying to profile my code where (hopefully) cudaMallocAsync calls are overlapped with another kernel execution, when I try to profile the program with nsys I can see the malloc call in the CUDA API row but not i…
@ax3l , on ThunderX2 the Spack built cuda provide nsys, but it does not process nsys profile a.out ie goes infinite loop.ikitayama added bug triage labels Sep 10, 2020 adamjstewart added the cuda label Sep 11, 2020 Member adamjstewart commented Sep 11, 2020 @ax3l @svenevs ...
