This problem is based on the distributed memory parallel algorithm for particle precipitation established in a previous challenge problem.

Your first task is to translate this into a distributed memory parallel implementation, which can take as a starting point the "PreCpitate solution C file" below.

You can use the "Precipitate Distributed Algorithm Solution txt" file below as a reference when implementing this distributed memory algorithm.

For simplicity's sake, your program only needs to work for cases in which the number of particles is divisible by the number of parallel processes.

It is recommended to use the Message Passing Interface (MPI) to implement the algorithm. MPI is a standard for distributed memory parallelism and has wide support for C and Fortran.

This problem builds on previous challenge problems linked below:
