.SH DESCRIPTION
.ft R
MPI_Comm_create_group is similar to MPI_Comm_create; however,
MPI_Comm_create must be called by all processes in the group of
comm, whereas MPI_Comm_create_group must be called by all processes in group,
which is a subgroup of the group of \fIcomm\fP. In addition, MPI_Comm_create_group
requires that \fIcomm\fP is an intracommunicator. MPI_Comm_create_group returns a new
intracommunicator, \fInewcomm\fP, for which the group argument defines the communication
group. No cached information propagates from \fIcomm\fP to \fInewcomm\fP.
Each process must provide a group argument that is a subgroup of the group associated with \fIcomm\fP;
this could be MPI_GROUP_EMPTY. If a non-empty group is specified, then all processes in that
group must call the function, and each of these processes must provide the same arguments,
including a group that contains the same members with the same ordering. Otherwise
the call is erroneous. If the calling process is a member of the group given as the \fIgroup\fP
argument, then newcomm is a communicator with group as its associated group. If the
calling process is not a member of group, e.g., \fIgroup\fP is MPI_GROUP_EMPTY, then the call
is a local operation and MPI_COMM_NULL is returned as \fInewcomm\fP.
.sp
.LP
.SH NOTES
MPI_Comm_create_group provides a means of making a subset of processes for the purpose of separate MIMD computation, with separate communication space. \fInewcomm\fR, which is created by MPI_Comm_create_group, can be used in subsequent calls to MPI_Comm_create_group (or other communicator constructors) to further subdivide a computation into parallel sub-computations. A more general service is provided by MPI_Comm_split.
.SH ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
.sp
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.

.ft R
MPI_Comm_dup_with_info acts exactly like MPI_Comm_dup except that the
info hints associated with the communicator \fIcomm\fP are not duplicated in \fInewcomm\fP. The
hints provided by the argument \fIinfo\fP are associated with the output communicator \fInewcomm\fP
instead.
.SH NOTES
This operation is used to provide a parallel
library call with a duplicate communication space that has the same properties as the original communicator. This includes any attributes (see below) and topologies (see Chapter 6, "Process Topologies," in the MPI-1 Standard). This call is valid even if there are pending point-to-point communications involving the communicator comm. A typical call might involve an MPI_Comm_dup_with_info at the beginning of the parallel call, and an MPI_Comm_free of that duplicated communicator at the end of the call. Other models of communicator management are also possible.
.sp
This call applies to both intra- and intercommunicators.

.SH DESCRIPTION
.ft R
MPI_Comm_idup starts the nonblocking duplication of an existing communicator comm with associated key
values. For each key value, the respective copy callback function determines the attribute value associated with this key in the new communicator; one particular action that a copy callback may take is to delete the attribute from the new communicator. Returns in newcomm a new communicator with the same group, any copied cached information, but a new context (see Section 5.7.1 of the MPI-1 Standard, "Functionality"). The communicator returned in \fInewcomm\fP will not be available until the request is complete.
.sp
The completion of a communicator duplication request can be determined by calling any of MPI_Wait, MPI_Waitany, MPI_Test, or MPI_Testany with the request returned by this function.
.SH NOTES
This operation is used to provide a parallel
library call with a duplicate communication space that has the same properties as the original communicator. This includes any attributes (see below) and topologies (see Chapter 6, "Process Topologies," in the MPI-1 Standard). This call is valid even if there are pending point-to-point communications involving the communicator comm.

.SH DESCRIPTION
.ft R
This function partitions the group associated with \fIcomm\fP into disjoint subgroups, based on
the type specied by \fIsplit_type\fP. Each subgroup contains all processes of the same type.
Within each subgroup, the processes are ranked in the order defined by the value of the
argument \fIkey\fP, with ties broken according to their rank in the old group. A new communicator
is created for each subgroup and returned in newcomm. This is a collective call;
all processes must provide the same \fIsplit_type\fP, but each process is permitted to provide
different values for key. An exception to this rule is that a process may supply the type
value MPI_UNDEFINED, in which case newcomm returns MPI_COMM_NULL.
.SH SPLIT TYPES
.ft R
.TP 1i
MPI_COMM_TYPE_SHARED
This type splits the communicator into subcommunicators, each of which can create a shared memory region.
.SH NOTES
.ft R
This is an extremely powerful mechanism for
dividing a single communicating group of processes into k subgroups, with k
chosen implicitly by the user (by the number of colors asserted over all
the processes). Each resulting communicator will be nonoverlapping. Such a division could be useful for defining a hierarchy of computations, such as for multigrid or linear algebra.
.sp
Multiple calls to MPI_Comm_split_type can be used to overcome the requirement that any call have no overlap of the resulting communicators (each process is of only one color per call). In this way, multiple overlapping communication structures can be created. Creative use of the color and key in such splitting operations is encouraged.
.sp
Note that keys need not be unique. It is MPI_Comm_split_type's responsibility to sort processes in ascending order according to this key, and to break ties in a consistent way. If all the keys are specified in the same way, then all the processes in a given color will have the relative rank order as they did in their parent group. (In general, they will have different ranks.)
.sp
Essentially, making the key value zero for all processes of a given split_type means that one needn't really pay attention to the rank-order of the processes in the new communicator.
.SH ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
.sp
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.

.SH DESCRIPTION
.ft R
MPI_Dist_graph_create creates a new communicator \fIcomm_dist_graph\fP with distrubuted
graph topology and returns a handle to the new communicator. The number of processes in
\fIcomm_dist_graph\fP is identical to the number of processes in \fIcomm_old\fP. Concretely, each process calls the
constructor with a set of directed (source,destination) communication edges as described below.
Every process passes an array of \fIn\fP source nodes in the \fIsources\fP array. For each source node, a
non-negative number of destination nodes is specied in the \fIdegrees\fP array. The destination
nodes are stored in the corresponding consecutive segment of the \fIdestinations\fP array. More
precisely, if the i-th node in sources is s, this species \fIdegrees\fP[i] \fIedges\fP (s,d) with d of the j-th
such edge stored in \fIdestinations\fP[\fIdegrees\fP[0]+...+\fIdegrees\fP[i-1]+j]. The weight of this edge is
stored in \fIweights\fP[\fIdegrees\fP[0]+...+\fIdegrees\fP[i-1]+j]. Both the \fIsources\fP and the \fIdestinations\fP arrays
may contain the same node more than once, and the order in which nodes are listed as
destinations or sources is not signicant. Similarly, different processes may specify edges
with the same source and destination nodes. Source and destination nodes must be process
ranks of comm_old. Different processes may specify different numbers of source and
destination nodes, as well as different source to destination edges. This allows a fully distributed
specification of the communication graph. Isolated processes (i.e., processes with
no outgoing or incoming edges, that is, processes that do not occur as source or destination
node in the graph specication) are allowed. The call to MPI_Dist_graph_create is collective.
If reorder = false, all processes will have the same rank in comm_dist_graph as in
comm_old. If reorder = true then the MPI library is free to remap to other processes (of
comm_old) in order to improve communication on the edges of the communication graph.
The weight associated with each edge is a hint to the MPI library about the amount or
intensity of communication on that edge, and may be used to compute a \"best\" reordering.
.SH WEIGHTS
.ft R
Weights are specied as non-negative integers and can be used to influence the process
remapping strategy and other internal MPI optimizations. For instance, approximate count
arguments of later communication calls along specic edges could be used as their edge
weights. Multiplicity of edges can likewise indicate more intense communication between
pairs of processes. However, the exact meaning of edge weights is not specied by the MPI
standard and is left to the implementation. An application can supply the special value
MPI_UNWEIGHTED for the weight array to indicate that all edges have the same (effectively no)
weight. It is erroneous to supply MPI_UNWEIGHTED for some but not
all processes of comm_old. If the graph is weighted but \fIn\fP = 0, then MPI_WEIGHTS_EMPTY
or any arbitrary array may be passed to weights. Note that MPI_UNWEIGHTED and
MPI_WEIGHTS_EMPTY are not special weight values; rather they are special values for the
total array argument. In Fortran, MPI_UNWEIGHTED and MPI_WEIGHTS_EMPTY are objects
like MPI_BOTTOM (not usable for initialization or assignment). See MPI-3 § 2.5.4.
.SH ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
.sp
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.

.SH DESCRIPTION
.ft R
MPI_Dist_graph_create_adjacent creats a new communicator \fIcomm_dist_graph\fP with distrubuted
graph topology and returns a handle to the new communicator. The number of processes in
\fIcomm_dist_graph\fP is identical to the number of processes in \fIcomm_old\fP. Each process passes all
information about its incoming and outgoing edges in the virtual distributed graph topology.
The calling processes must ensure that each edge of the graph is described in the source
and in the destination process with the same weights. If there are multiple edges for a given
(source,dest) pair, then the sequence of the weights of these edges does not matter. The
complete communication topology is the combination of all edges shown in the \fIsources\fP arrays
of all processes in comm_old, which must be identical to the combination of all edges shown
in the \fIdestinations\fP arrays. Source and destination ranks must be process ranks of comm_old.
This allows a fully distributed specication of the communication graph. Isolated processes
(i.e., processes with no outgoing or incoming edges, that is, processes that have specied
indegree and outdegree as zero and thus do not occur as source or destination rank in the
graph specication) are allowed. The call to MPI_Dist_graph_create_adjacent is collective.
.SH WEIGHTS
.ft R
Weights are specied as non-negative integers and can be used to influence the process
remapping strategy and other internal MPI optimizations. For instance, approximate count
arguments of later communication calls along specic edges could be used as their edge
weights. Multiplicity of edges can likewise indicate more intense communication between
pairs of processes. However, the exact meaning of edge weights is not specied by the MPI
standard and is left to the implementation. An application can supply the special value
MPI_UNWEIGHTED for the weight array to indicate that all edges have the same (effectively
no) weight. It is erroneous to supply MPI_UNWEIGHTED for some but not all processes of
comm_old. If the graph is weighted but \fIindegree\fP or \fIoutdegree\fP is zero, then
MPI_WEIGHTS_EMPTY or any arbitrary array may be passed to sourceweights or destweights
respectively. Note that MPI_UNWEIGHTED and MPI_WEIGHTS_EMPTY are not special weight values;
rather they are special values for the total array argument. In Fortran, MPI_UNWEIGHTED
and MPI_WEIGHTS_EMPTY are objects like MPI_BOTTOM (not usable for initialization or
assignment). See MPI-3 § 2.5.4.
.SH ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
.sp
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.

.SH DESCRIPTION
.ft R
MPI_Reduce_scatter_block first does an element-wise reduction on vector of \fIcount\fP\
=\ n * \fIrevcount\fP elements in the send buffer defined by \fIsendbuf\fP, \fIcount\fP, and
\fIdatatype\fP, using the operation \fIop\fP, where n is the number of
processes in the group of \fIcomm\fP. Next, the resulting vector of results is split into n disjoint
segments, where n is the number of processes in the group. Each segments contains \fIrecvcount\fP
elements. The ith segment is sent to process i and stored in the receive buffer defined by
\fIrecvbuf\fP, \fIrecvcount\fP, and \fIdatatype\fP.
.SH USE OF IN-PLACE OPTION
When the communicator is an intracommunicator, you can perform a reduce-scatter operation in-place (the output buffer is used as the input buffer). Use the variable MPI_IN_PLACE as the value of the \fIsendbuf\fR. In this case, the input data is taken from the top of the receive buffer. The area occupied by the input data may be either longer or shorter than the data filled by the output data.

.SH WHEN COMMUNICATOR IS AN INTER-COMMUNICATOR
.sp
When the communicator is an inter-communicator, the reduce-scatter operation occurs in two phases. First, the result of the reduction performed on the data provided by the processes in the first group is scattered among the processes in the second group. Then the reverse occurs: the reduction performed on the data provided by the processes in the second group is scattered among the processes in the first group. For each group, all processes provide the same \fIrecvcounts\fR argument, and the sum of the \fIrecvcounts\fR values should be the same for both groups.

.SH NOTES ON COLLECTIVE OPERATIONS
The reduction functions (
.I MPI_Op
) do not return an error value. As a result,
if the functions detect an error, all they can do is either call
.I MPI_Abort
or silently skip the problem. Thus, if you change the error handler from
.I MPI_ERRORS_ARE_FATAL
to something else, for example,
.I MPI_ERRORS_RETURN
,
then no error may be indicated.
The reason for this is the performance problems in ensuring that
all collective routines return the same error value.
.SH ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
.sp
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
