Nsight System profiles CUDA memory copies and when .qdrep file generated through nsys is loaded into the Nsight System GUI, Source and Destination device IDs can be seen for peer-to-peer memcopies. Whereas, if nsys --export=sqlite option is used, the CUPTI_ACTIVITY_KIND_MEMCPY table is missing these src and destination device IDs. Is there any other option in nsys tracing or writing a query in the sqlite tables to extract this information? Or can these ids can be added to CUPTI_ACTIVITY_KIND_MEMCPY table for sqlite format?
