I use pgc++ 13.1 to compile OpenACC program. It is quite difficult for me to understand the parallel program deeply without a debugg tool. In CUDA, I could freely jump from one thread to another to investigate the problem. I have tried with PGI_ACC_NOTIFY or nvprof but I think this is not enough. I heard CRAY supports debugging their OpenACC program with TotalView.
So, does the Portland group have plan to write a debug tool soon? And why this feature is missing from pgi compiler?
