The README file for parallel tree, pC++tree,  version 0.1

-- Installation and usage

Installation:

This is an alpha-testing version of pC++tree. The following is the
minimal guide for installation.

1) Get the archive from

http://grape.astron.s.u-tokyo.ac.jp/~makino/softwares/pC++tree/

2) extract it at a directory dedicated for it.

3) Edit the Makefile (and Makefile.nemo) according to your need
   In most cases, you would need to change the following two lines for 
   Makefile

G6LIB =  -L../g6hib-x86/ -lg6lx  -L../grape6-x86 -lg6lxsim2  -lm
G6DIR = ../g6hib-x86

and for Makefile.nemo, well, I do not really  know...

4) Create executables by

make nbody
make nbody_g6
make splitsnap
make -f Makefile.nemo stopa

If you have parallel system (MPICH based), you can try
make nbody_MPI
make nbody_g6_MPI
make splitsnap


If your compilation fails, well, ... if all else fails, send Email to
me.

Usage:

The main time integrator is nbody[_g6][_MPI]. Try

 nbody_g6 -h

which should print out:

Myid:0 Initialize end
list of options
-i        name of snapshot input file       (no default)
-o        name of snapshot output file      (default: no output)
-d        timestep                          (default: 0.015625)
-D        time interval for snapshot output (default: 1)
-l        interval for log output (default: 1: all step)
-T        time to stop integration          (default: 10)
-e        softening parameter epsilon2      (default: 0.025)

-n        ncrit for Barnes' vectrization    (default: 8192)
          (ONLY used with GRAPE/HARP inplementation)
-w        window size for PGPLOT snapshot plot (default: 10)
-s        scale factor for position scaling (default: 1)
-S        scale factor for velocity scaling (default: 1)
-h        print this help

The file format for input snapshot is *not* the good old stoa format.
You should use stopa to create the input file. The output snapshot is
in stoa format. I hope other options are self-descriptive.

The usage of stopa is the same as stoa.

parallel version need "splitted" input file, which is made by
splitsnap. Its input is the output of stopa. For example,

splitsnap -i testin32k  -o testin32k -n 4
creates 4 "splitted" files,  testin32kMP4-[0-3].

To run 4-cpu job, you would say
mpirun -np 4 nbody[_g6]_MPI -i testin32k ...

Each MPI node reads  its input snapshot (testin32kMP4-0 for node 0
etc). Output is also created individually in stoa format. Note that
with the present version particle identity is *not* retained in the
snapshot output from MPI run... The next version will take cate of
this limitation.

The following is a sample output created by:

nbody_g6 -i testin32k -T 0.5 > samplelog

on an K7 (XP1800+) front end with 128 chip GRAPE-6. If you get very
different result (either in time or errors in enery etc), something
must be wrong...
