All processes that can share memory are grouped into the same communicator.

A group containing no members.

Identical

(only for 'MPI_COMM_COMPARE') The groups are identical

Same members, but in a different order

Different

Has value 1 if 'MPI_WTIME' is globally synchronized.

Number of available processes. See the standard for a description of limitations on this value

Last used MPI error code (check:: code or class?)

Used by many routines to indicated undefined or unknown integer value

Unknown rank

Special keyval that may be used to detect uninitialized keyvals.

Add this to the size of a 'MPI_BSEND' buffer for each outstanding message

This rank may be used to send or receive from no-one.

In a receive, accept a message from anyone.

In a receive, accept a message with any tag value.

May be used to indicate the bottom of the address space

Special location for buffer in some collective communication routines

Use automatic (unlimited) buffering in buffered send

Numeric value of MPI version (e.g., 3)

Numeric value of MPI subversion (e.g., 1)

Cartesian grid

General graph

General distributed graph

Indicates that the edges are unweighted

Special address that indicates no array of weights information

Read only

Read and write

Write only

Create the file if it does not exist

It is an error if creating a file that already exists

Delete the file on close

The file will not be concurrently opened elsewhere

The initial position of all file pointers is at the end of the file

File will only be accessed sequentially

Use with files opened with mode 'MPI_MODE_SEQUENTIAL' in calls to 'MPI_FILE_SET_VIEW'

Set the pointer to 'offset'

Set the pointer to the current position plus 'offset'

Set the pointer to the end of the file plus 'offset'

window base address.

window size, in bytes

displacement unit associated with the window

how the window was created

memory model for window

Window was created with MPI_WIN_CREATE.

Window was created with MPI_WIN_ALLOCATE.

Window was created with MPI_WIN_CREATE_DYNAMIC.

Window was created with MPI_WIN_ALLOCATE_SHARED.

Separate public and private copies of window memory

The public and private copies are identical (by which we mean that updates are eventually observed without additional RMA operations)

Only one process at a time will execute accesses within the lock

Not exclusive; multiple processes may execute accesses within the lock

Contains the execution environment

Ignore a single 'MPI_Status' argument

Ignore an array of 'MPI_Status'

Ignore an array of error codes
