Needs

• The library must be able to handle split meshes by indexing matched faces between mesh partitions.
• During runtime the PPF must be able to make the following decisions correctly:
  • when to stop tracking particles on a partial mesh and send particles frozen on a split surface to another domain
  • how many particles to buffer before sending
  • how often to perform checks whether or not to send buffered particles
  • when to ask if another domain is ready to send particles
  • how to handle load balancing if possible
  • what to do if one domain ends up with too many particles to fit in memory
• Particles must be sent as efficiently as possible.
  • particles should not be packaged with extra information for sending
  • data should only be sent to nodes which require it, no broadcasts
• Particle transfers between nodes must be accurate.
• The library's interface must be intuitive and not dependent on a prior knowledge in distributed computing.
