PMON -- Parallaxis Timing Tool
==================================
Pmon is part of the Parallaxis parallel programming project at Univ. Stuttgart,
Germany. Parallaxis compilers, simulator, debugger, sample programs, and
programming environment tools are distributed as Public Domain Software without
any warranty of any kind. See the notice in the main Parallxais README file.

1. Intro:
---------
This is a brief documentation for the Parallaxis Timing Tool 'pmon'.
'pmon' processes recording files, created by the PARZ simulator 'pz' or
by a program run after compilation with 'pz2c' or 'pz2mpl'.
'pmon' calculates statistical information, e.g. the distribution of
different statement types, average PE load or the ratio between scalar and
vectorial statements and display the load of the PEs in a graphical window.
2. Usage:
---------
2.1 Generation of the record file:
----------------------------------
* When using the simulator 'pz', call 'pz' with the option '-r'.
'pz' then writes a recording file '.rec'.
E.g. 'pz -r prim.z' results in the record file 'prim.rec'.
* When using the compilers 'pz2c' and 'pz2mpl',
call 'pz2c' with the option '-R'.
After the program run, a file '.rec' exists, containing the record file.
E.g. 'pz2c -R prim.z ; prim' results in the record file 'prim.rec'.
2.2 Calling 'pmon':
-------------------
Type 'pmon <file>.rec' to process the recording file '<file>.rec'.
After a few seconds, two windows will appear, one containing a dialog box,
the other containing the load diagram. Choose the button 'Help' and read the
explanations to understand the usage of 'pmon'.
Pressing the button 'Print Graphics' creates a file '<file>.ps.
This file contains four diagrams in PostScript format. You can print these
graphics on a PostScript printer or display them using PostScript previewers
like 'ghostview'.
