l1 shared bank conflict profiler counter for CUDA CC 3.0


What is the new l1_shared_bank_conflict (or the equivalent) counter for CUDA with CC 3.0? In CUPTI User Guide, it says shared_[load|store]_bank_conflict, but it didn't show when I tried so.

I'm using the command line profiler in Linux.


Solution

  • Some of the new counters are not supported by the old command line profiler. If you are using CUDA 5, you can try nvprof:

    nvprof --events l1_shared_bank_conflict <app_name>
    
    nvprof --query-events
    

    See http://docs.nvidia.com/cuda/profiler-users-guide/index.html#nvprof-overview
