[bgl-discuss] Profile problem

["Xu, Jin" <jin_xu@xxxxxxx>]

Hi,

  I am trying to profile code, but met problems. First is compiling with "-qdebug=function_trace" option. I use xlc compiler to compile C/C++ code.

  work/Hybrid> cat Makefile.xlc.trace

   I also tried compiling with -pg option:

>GPROF
>
>   Compile your code with the "-pg" flag.
>   You will get a gmon.out file.
>         gprof myExe gmon.out.*
>

And I run the job as usual,

cqsub -t 5:00 -n 16 -c 16 -m vn /home/jinxu/work/Hybrid/runs/turbulence180e.pg

but does not get gmon.out files. What's wrong?


Thanks,

Jin
