Aggregate profiling data collected by -profile-functions in the compiler flag

266 Views

Hi All,

I intend to profile the Community Earth System Model (CESM) climate application. I am running this MPI code on 8 nodes (each with 16 core processors and hence entirely 128 processors and I run 128 processes -1 on each processor). I want to find out the execution times of the fortran functions along with the number of calls made.

I am profiling at the compiler stage by adding -profile-functions flag as the compiler flags. This is helping me get the statistics over different files (dump and xml files). I wanted to know if there is anyway I can aggregate the statistics over these files. This will help me identify hotspots, right?

Thanks,

Aketh.
