Dear colleagues,
I wonder if somebody who uses PVM could help me. I am having trouble
measuring the time taken by some application programs written in FORTRAN 77
and run on a network of SUN4s.
Apparently the execution time returned by the function ``dtime'' is that of
the application program only and is not including the time taken by the
daemons to actually transfer the data. Any suggestions? Shall I use a
similar approach to that in the program ``timing.c'' that comes with PVM,
which uses the ``gettimeofday'' routine?
Thanks in advance!
