NAME
     bspcgprof - The Oxford BSP Toolset call-graph  profiler  for
     BSPlib


SYNOPSIS
     bspcgprof [-v] [-help] [-hide _p_e_r_c_e_n_t_a_g_e] _f_i_l_e_n_a_m_e


DESCRIPTION
     bspcgprof visualises the call-graph from the execution of  a
     BSPlib  program.  Call-graph  trace  files  are generated by
     adding the option -_c_g_p_r_o_f  when  compiling  BSPlib  programs
     with bspfront(1).


OPTIONS
     -v    Print (on standard error output) the  phases  involved
          in  the  execution  of  the  profiler.  The option also
          prints the version number of the profiler.

     -help
          Print this manual page on standard output.

     -hide _p_e_r_c_e_n_t_a_g_e
          Contract all nodes in the call-graph that have an accu-
          mulated  computation  and  communication time less then
          _p_e_r_c_e_n_t_a_g_e of the total running time.

     -normalise _v_a_l_u_e
          When visulalising the critical  path  with  respect  to
          relative   imbalance,   set  _v_a_l_u_e  as  an  upper-bound
          thereashold, i.e., all imbalances  greater  than  _v_a_l_u_e
          will be equivalent.
