allow more than one pending message in the communication system #126

Closed sebhtml closed 11 years ago

sebhtml commented 11 years ago

In the communication system with n MPI ranks, m messages will be sent during a job.

Assuming uniformity, that's m/n messages sent per MPI rank. Also assuming uniformity, that's m/n messages received per MPI rank. If the problem remains the same (m is constant) and n grows, then any MPI rank will receive less messages.

this is not trivial

it's easier to reduce granularity
