L1 Generic Conflict Profilers Counter for CUDA CC 3.0

Question

What is the new l1_shared_bank_conflict (or equivalent) counter for CUDA with CC 3.0? The CUPTI user guide says that shared_ [load | store] _bank_conflict, but it didn’t show when I tried to do this.

I am using a command line profiler on Linux.

Answer 1

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
