Module mpi::point_to_point [−] [src]

Point to point communication

Endpoints of communication are mostly described by types that implement the Source and Destination trait. Communication operations are implemented as default methods on those traits.

Unfinished features

3.2.6: MPI_STATUS_IGNORE
3.6: Buffer usage, MPI_Buffer_attach(), MPI_Buffer_detach()
3.9: Persistent requests, MPI_Send_init(), MPI_Bsend_init(), MPI_Ssend_init(), MPI_Rsend_init(), MPI_Recv_init(), MPI_Start(), MPI_Startall()

Point to point communication traits

Structs

Message	Describes a pending incoming message, probed by a `matched_probe()`.
ReceiveFuture	Will contain a value of type `T` received via a non-blocking receive operation.
Status	Describes the result of a point to point receive operation.

Traits

Destination	Something that can be used as the destination in a point to point send operation
MatchedReceiveVec	Receive a previously probed message containing multiple instances of type `Msg` into a `Vec`.
Source	Something that can be used as the source in a point to point receive operation

Functions

send_receive	Sends `msg` to `destination` and simultaneously receives an instance of `R` from `source`.
send_receive_into	Sends the contents of `msg` to `destination` and simultaneously receives a message from `source` into `buf`.
send_receive_into_with_tags	Sends the contents of `msg` to `destination` tagging it `sendtag` and simultaneously receives a message tagged `receivetag` from `source` into `buf`.
send_receive_replace_into	Sends the contents of `buf` to `destination` and simultaneously receives a message from `source` and replaces the contents of `buf` with it.
send_receive_replace_into_with_tags	Sends the contents of `buf` to `destination` tagging it `sendtag` and simultaneously receives a message tagged `receivetag` from `source` and replaces the contents of `buf` with it.
send_receive_with_tags	Sends `msg` to `destination` tagging it `sendtag` and simultaneously receives an instance of `R` tagged `receivetag` from `source`.
