Detailed Description
Performs a linear partition scheme of an SST simulation configuration.
In this scheme a list of components (supplied as a graph) are grouped by slicing the list into approximately equal parts. A "part" is generated for each MPI rank performing the simulation. This means Components with sequential ids will be placed close together. In general this scheme provides a very effective partition for most parallel simulations which generate man similar components of interest close together in the input Python configuration. It is also very fast to compute a linear partition scheme. For more aggressive partition schemes users should try either a simple or Zoltan-based partitioner.
