The README file for parallel tree, pC++tree, version 0.1 Copyright 2002 Jun Makino -- Copyright of the code: See COPYRIGHT file -- 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) -t opening angle theta (default: 0.75) -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... ---------------------------------------------------------------------------- dt= 0.015625
