I want to improve HPC application performance, like HPCC.
First, I try to rewrite HPL source code under folder $(HPL_dir)/src/
But when I finished it, I found that I can’t use pgprof to analysis my code to confirm if I get a better performance than before without executable file .
Even though I use make file to build it (I haven’t finished yet because of another problem), I only get one executable file.
I don’t think one executable file can help me to analysis many code (more then one) behind it.
Did anyone ever use PGI compiler to modify application and get better performance? I really want to know how can I analysis my code, or other method to help me confirm new code performance.
