- SSEECCOONNDDRR - Returns elapsed wall-clock time in seconds
-
- SSYYNNOOPPSSIISS
- All systems:
-
- RREEAALL ((KKIINNDD==88)) SSEECCOONNDDRR
- _t_i_m_e=SSEECCOONNDDRR(( ))
-
- UNICOS systems:
-
- CCAALLLL SSEECCOONNDDRR((_t_i_m_e))
-
- IIMMPPLLEEMMEENNTTAATTIIOONN
- UNICOS, UNICOS/mk, and IRIX systems
-
- DDEESSCCRRIIPPTTIIOONN
- On IRIX systems, this routine is in lliibbffffiioo..ssoo which is linked by
- default when compiling programs with the MIPSpro 7 Fortran 90 compiler
- or when compiling programs with the --ccrraayylliibbss option to the MIPSpro
- F77 compiler.
-
- SSEECCOONNDDRR can be called several times during the execution of a program
- to determine the amount of elapsed wall-clock time.
-
- _t_i_m_e is the real-time clock values in floating-point seconds. If the
- value of the real-time clock exceeds 48 bits, some accuracy may be
- lost during the conversion to float. The argument must be of type
- real with KKIINNDD==88.
-
- On UNICOS/mk systems, the real-time clocks on processing elements are
- not synchronized with each other. Therefore, a SSEECCOONNDDRR() value should
- not be compared to a previous SSEECCOONNDDRR() taken on a different
- processing element.
-
- EEXXAAMMPPLLEESS
- This example calculates the elapsed wall-clock time from the first
- call to SSEECCOONNDDRR until the second call to SSEECCOONNDDRR.
