Subject: [Boost-users] [mpi] potentially blocking send - require blocking
From: Dave Clarke (dave.p.clarke_at_[hidden])

The boost::mpi documentation for send() is:
"This routine executes a potentially blocking send"
This differs from MPI_Send()
"This routine will block until the message is sent to the destination."
I am developing an application which requires the code not to progress
until the communication is complete.
In which situations does "potentially blocking" apply?
And, is there a way of guaranteeing it is complete, the equivalent of
MPI_Wait() for MPI_Isend()?

Dave
