**
** DESCRIPTION
** sample timing routine for the cray-t3d using the rtclock(3C)
** function
**
** NOTES
** this program first calls rtclock() to initialize any internal
** tables/etc that might need taking care of.
**
** then a calibration value is computed by taking the difference
** of two subsequent calls to rtclock() -- this calibration time
** will be subtracted from the timed portions of the code in order
** to avoid calls to rtclock() being incorporated into the times
** of the timed functions
**
** finally the sleep(3C) function is timed and the values printed
** to stdout
**
** SAMPLE OUTPUT for WAIT_TIME 1
** h4p:final>./a.out -npes 4
** time (secs): 1.047676 time (ticks): 157167093
** calibration (ticks): 28 ticks per second: 150015001
** time (secs): 1.047680 time (ticks): 157167675
** calibration (ticks): 28 ticks per second: 150015001
