I want to write a program for measuring cpu time taken by each subroutine
in a program. The program is pretty large (about 300 subroutines) and a number
of subroutines take very little cpu time and are called repeatedly (some
tens of thousand times).Is there a package which can be linked to the
program package to be tested, which will do the job. I understand there is
DEC package which tests the pc every few seconds (of real elapsed time), but th
is would not be useful, since I want to measure the cpu time.
Another question I have is : I see in the documentation that the cpu
time is given in tens of millisecs. I there any undocumented instruction for
obtaing the cpu time interval with a finer resolution? If there is no such
instruction is there any piece of code available to do the same using the
hardware timer (which seems to have a finer resolution)?
Thanks in advance
