Hello Everybody...
I am trying to profile my UPC code and analyse its performance as the number
of threads increase. I am getting a good scale up. But, When I installed UPC
with --enable-debug option and I compile my code with -pg option and run it,
it says
"This application was built from a Berkeley UPC installation that
was configured and built with these optional features enabled:
debugging tracing statistics
This usually has a SERIOUS impact on performance, so you should NOT
trust any performance numbers reported in this program run!!!
To suppress this message, pass '-quiet' to the upcrun command or set
the UPC_NO_WARN or UPC_QUIET environment variables."
My question is: Can I rely on the numbers it gives in the profiled information
obtained by executing "gprof a.out > result.txt" for my analysis? (i.e the
numbers-time,%time given per method). How else can will I know abt the
performance if not for using the profiler?
Plz suggest
Thanks
Sirisha
