Detailed Description

Determines the order in which a set of processors should communicate with one another.

The communication order should

have maximum overlap
allow blocking communication without deadlock

Does a very simple scheduling which assumes same time for all operations.

After construction:

schedule() gives the order in which the input communication should occur
procSchedule()[proci] gives per proci

Does not care whether 'talking' is first send, second receive or maybe full swap. This is all responsibility of caller. See ProcessorTopology class for use in scheduling processor boundary swaps.
