John,
We have etime, not second(). Here is what the man page says - is dtime
what I want for a multi-cpu test?
> SYNOPSIS
> EXTERNAL ETIME
> REAL ETIME
> REAL TARRAY(2)
> REAL TSECS
> TSECS = ETIME(TARRAY)
>
> EXTERNAL DTIME
> REAL DTIME
> REAL TARRAY(2)
> REAL DTSECS
> DTSECS = DTIME(TARRAY)
>
> DESCRIPTION
> These two routines return elapsed runtime in seconds for the
> calling process. DTIME returns the elapsed time since the
> last call to DTIME or the start of execution on the first
> call.
>
> The argument array returns user time in the first element
> and system time in the second element. The function value
> is the sum of user and system time.
>
> The resolution of all timing is 1/100th of a second.
The output:
--------------------------------------
Double precision appears to have 16 digits of accuracy
Assuming 8 bytes per DOUBLEPRECISION word
--------------------------------------
Timing calibration ; time = 749.0000307559967 hundredths
of a second
Increase the size of the arrays if this is <30 and your clock
precision is =<1/100 second
