The following C++ software package produces a parallel--in--time solution of a system of initial value problems given user supplied code for the right hand side of the system and a sequential code for a first-order time step. The user supplied time step routine may be explicit or implicit and may make use of any auxiliary libraries which take care of the solution of any nonlinear algebraic systems which may arise or the numerical linear algebra required. The code contains six examples of increasing complexity which also serve as templates to solve user defined problems.

This C++ library provides:

- data structures and functions for generating a hierarichal tree structure of particles
- computation of moments and Taylor approximations of the canonical 1/r electrostatic potential and the exp(-kr)/r potentials that are used in ...
- a treecode approximation of the potential solution arising from Poisson's or Helmholtz equation.
