This is a Barnes-Hut simulator written on top of Charm++.

To build:
1. Edit the Makefile CHARM_PATH to point to your built copy of Charm++.
2. Edit the Makefile STRUCTURES_PATH to point to the Changa structures library.
   git clone https://github.com/N-BodyShop/utility
   STRUCTURES_PATH = utility/structures
3. make

Usage:
1. Prepare a data file with 10K particles:
   ./plummer 10000 particles.bin
2. Run on a single processor with 100 TreePieces and 50 iterations
   ./charmrun +p1 ./barnes -in=particles.bin -p=100 -killat=50
