bsp_time(3)             BSPlib FUNCTIONS              bsp_time(3)



NAME
     bsp_time - high-precision real-time clock.



C SYNOPSIS
     #include "bsp.h"

     double bsp_time();

FORTRAN SYNOPSIS
     INCLUDE 'fbsp.h'

     DOUBLE PRECISION FUNCTION bsptime()


DESCRIPTION
     The function bsp_time provides access  to  a  high-precision
     clock. The accuracy of the timer is implementation specific.
     The function is a local operation of each process,  and  can
     be  issued  at  any point after bsp_begin. The result of the
     timer is the time in seconds since bsp_begin. The  semantics
     of  bsp_time  is  as though there are bsp_nprocs timers, one
     per process.  BSPlib does  _n_o_t  _i_m_p_o_s_e  _a_n_y  _s_y_n_c_h_r_o_n_i_s_a_t_i_o_n
