Dear Friends,

I have a fortran90 program with different subroutines. I would like to know the time taken for execution of each subroutine. It would be nice if anyone could point out how this can be achieved.

Thanks in advance,

Regards,

Ganesh

real*4 :: t0, t1, elapsed

call cpu_time(t0) call RotineToBeTracked call cpu_time(t1)

elapsed = t1-t0

Dear Anonymous,

Thanks for the speedy reply. It has helped me a lot

Regards,

Ganesh

You probably want to use a program called a profiler. Look in your manual to find details. On Linux gprof is one such program.

Adding timing statements works but is the equivalent of using print statements to debug instead of using a debugger program.
