Name
HPL_ptimer_walltime Return the elapsed (wall-clock) time.
Synopsis
#include <hpl.h>
double
HPL_ptimer_walltime();
Description
HPL_ptimer_walltime
returns the elapsed (wall-clock) time.
If HPL_USE_PentiumCPS is defined to be the clock cycle per second on
an i[56]86 Intel processor (e.g., HPL_USE_PentiumCPS is defined to be
300 on a 300 Mhz Pentium processor), we read the internal processor
counters. If HPL_USE_GETTIMEOFDAY is defined, the gettimeofday()
function is used to return the elapsed wallclock time of the system.
Otherwise, the MPI_Wtime() function is used (default).
