Previous: Procedure Specification
When discussing MPI procedures the following semantic
terms are used. The first two are usually applied to communication
operations.
-
{ nonblocking}
-
If the procedure may return before the
operation completes, and before the user is allowed to re-use
resources (such as buffers) specified in the call.
-
{ blocking}
-
If return from the procedure indicates the user
is allowed to re-use resources specified in the call.
-
{ local}
-
If completion of the procedure depends only on the
local executing process. Such an operation does not require
communication with another user process.
-
{ non-local}
-
If completion of the operation may require
the execution of some MPI procedure on another process. Such an
operation may require
communication occurring with another user process.
-
{ collective}
-
If all processes in a process group need
to invoke the procedure.
