HPL_timer_cputime — Return the CPU time.


#include "hpl.h"
 double HPL_timer_cputime();


HPL_timer_cputime returns the cpu time.  If HPL_USE_CLOCK is defined, the  clock() function is used to return an approximation of processor time used by the program.  The value returned is the CPU time used so far as a clock_t;  to get the number of seconds used,  the result  is divided by  CLOCKS_PER_SEC.  This function is part of the  ANSI/ISO C standard library.  If  HPL_USE_TIMES is defined, the times() function is used instead.  This  function  returns  the current process times. times() returns the number of clock ticks that have elapsed since the system has been up.  Otherwise and by default,  the  standard library function getrusage() is used.
