Subject: [OMPI users] Message queue in MPI?
From: John Chludzinski (john.chludzinski_at_[hidden])

If I'm using MPI_Send(...) and MPI_Recv(...) in a producer/consumer
model and choose not to buffer messages internally (in the app),
allowing them to acumulate in the MPI layer, how large of an MPI
message queue can I expect before something breaks?
