An attribute vector is a scheme for storing bundles of integer and real data vectors, indexed by the names of the fields stored in List format (see the mpeu module m_List for more information about the List datatype). The ordering of the fieldnames in the integer and real attribute List components (AttrVect%iList and AttrVect%rList, respectively) corresponds to the storage order of the attributes in their respective data buffers (the components AttrVect%iAttr(:,:) and AttrVect%rAttr(:,:), respectively). The organization of the fieldnames in List format, along with the direct mapping between List items and locations in the data buffer, allows the user to have random access to the field data. This approach also allows the user to set the number and the names of fields stored in an AttrVect at run-time.
The AttrVect stores field data in a pointwise fashion (that is, the data are grouped so that all the integer or real data associated with an individual point are adjacent to each other in memory. This amounts to the having the integer and real field data arrays in the AttrVect (the components AttrVect%iAttr(:,:) and AttrVect%rAttr(:,:), respectively) having the attribute index as the major (or fastest-varying) index. A prime example of this is observational data input to a data assimilation system. In the Model Coupling Toolkit, this datatype is the fundamental type for storing field data exchanged by component models, and forms a basis for other MCT datatypes that encapsulate time accumulation/averaging buffers (the Accumulator datatype defined in the module m_Accumulator), coordinate grid information (the GeneralGrid datatype defined in the module m_GeneralGrid), and sparse interpolation matrices (the SparseMatrix datatype defined in the module m_SparseMatrix).
The attribute vector is implemented in Fortran 90 using the AttrVect derived type. This module contains the definition of the AttrVect, and the numerous methods that service it. There are a number of initialization (creation) schemes, and a routine for zeroing out the elements of an AttrVect. There is a method to clean up allocated memory used by an AttrVect (destruction). There are numerous query methods that return: the number of datapoints (or length; the numbers of integer and real attributes; the data buffer index of a given real or integer attribute; and return the lists of real and integer attributes. There also exist methods for exporting a given attribute as a one-dimensional array and importing a given attribute from a one-dimensional array. There is a method for copying attributes from one AttrVect to another. There is also a method for cross-indexing the attributes in two AttrVect variables. In addition, there are methods that return those cross-indexed attributes along with some auxiliary data in a AVSharedIndicesOneType or AVSharedIndices structure. Finally, there are methods for sorting and permuting AttrVect entries using a MergeSort scheme keyed by the attributes of the AttrVect.

This routine creates an AttrVect (the output argument aV) using the optional input CHARACTER arguments iList, and rList to define its integer and real attributes, respectively. The optional input INTEGER argument lsize defines the number of points for which we are storing attributes, or the length of aV. The expected form for the arguments iList and rList are colon-delimited strings where each substring defines an attribute. Suppose we wish to store N observations that have the real attributes 'latitude', 'longitude', pressure, 'u-wind', and 'v-wind'. Suppose we also wish to store the integer attributes 'hour', 'day', 'month', 'year', and 'data source'. This can be accomplished by invoking init_() as follows:
call init_(aV, 'hour:day:month:year:data source', &
'latitude:longitude:pressure:u-wind:v-wind', N)
The resulting AttrVect aV will have five integer
attributes, five real attributes, and length N.

This routine initializes an AttrVect directly from input List data type arguments iList and rList (see the module m_List in mpeu for further details), and an input length lsize. The resulting AttrVect is returned in the argument aV.
N.B.: If the user supplies an empty list for the arguments iList (rList), then aV will be created only with REAL (INTEGER) attributes. If both arguments iList and rList are empty, the routine will terminate execution and report an error.
N.B.: The outcome of this routine, aV represents allocated memory. When this AttrVect is no longer needed, it must be deallocated by invoking the routine AttrVect_clean(). Failure to do so will spawn a memory leak.

This routine deallocates the allocated memory structures of the input/output AttrVect argument aV. This amounts to cleaning the List structures aV%iList and av%rList, and deallocating the arrays aV%iAttr(:,:) and aV%rAttr(:,:). The success (failure) of this operation is signified by a zero (non-zero) value of the optional INTEGER output argument stat. If clean_() is invoked without supplying stat, and any of the deallocation operations fail, the routine will terminate with an error message.

This routine extracts from the input AttrVect argument aV the integer attribute corresponding to the tag defined in the input CHARACTER argument AttrTag, and returns it in the INTEGER output array outVect, and its length in the output INTEGER argument lsize. The optional input CHARACTER arguments perrWith and dieWith control how errors are handled.
N.B.: This routine will fail if the AttrTag is not in the AttrVect List component aV%iList.
N.B.: The flexibility of this routine regarding the pointer association status of the output argument outVect means the user must invoke this routine with care. If the user wishes this routine to fill a pre-allocated array, then obviously this array must be allocated prior to calling this routine. If the user wishes that the routine create the output argument array outVect, then the user must ensure this pointer is not allocated (i.e. the user must nullify this pointer) before this routine is invoked.
N.B.: If the user has relied on this routine to allocate memory associated with the pointer outVect, then the user is responsible for deallocating this array once it is no longer needed. Failure to do so will result in a memory leak.

This module defines the communications methods for the AttrVect datatype (see the module m_AttrVect for more information about this class and its methods). MCT's communications are implemented in terms of the Message Passing Interface (MPI) standard, and we have as best as possible, made the interfaces to these routines appear as similar as possible to the corresponding MPI routines. For the AttrVect, we supply blocking point-to-point send and receive operations. We also supply the following collective operations: broadcast, gather, and scatter. The gather and scatter operations rely on domain decomposition descriptors that are defined elsewhere in MCT: the GlobalMap, which is a one-dimensional decomposition (see the MCT module m_GlobalMap for more details); and the GlobalSegMap, which is a segmented decomposition capable of supporting multidimensional domain decompositions (see the MCT module m_GlobalSegMap for more details).

Added more error checking in gsm scatter. Fixed minor bugs
in gsm and gm gather.

This routine takes an input AttrVect argument inAV and sends it to processor dest on the communicator associated with the Fortran INTEGER MPI communicator handle comm. The overalll message is tagged by the input INTEGER argument TagBase. The success (failure) of this operation is reported in the zero (nonzero) optional output argument status.
N.B.: One must avoid assigning elsewhere the MPI tag values between TagBase and TagBase+7, inclusive. This is because send_() performs the send of the AttrVect as a series of eight send operations.

The overall message is tagged by the input INTEGER argument TagBase. The success (failure) of this operation is reported in the zero (nonzero) optional output argument status.
N.B.: One must avoid assigning elsewhere the MPI tag values between TagBase and TagBase+7, inclusive. This is because recv_() performs the receive of the AttrVect as a series of eight receive operations.

The routine GSM_gather_() takes a distributed input AttrVect argument iV, whose decomposition is described by the input GlobalSegMap argument GSMap, and gathers it to the output AttrVect argument oV. The gathered AttrVect oV is valid only on the root process specified by the input argument root. The communicator used to gather the data is specified by the argument comm. The success (failure) is reported in the zero (non-zero) value of the output argument stat.
GSM_gather_() converts the problem of gathering data according to a GlobalSegMap into the simpler problem of gathering data as specified by a GlobalMap. The GlobalMap variable GMap is created based on the local storage requirements for each distributed piece of iV. On the root, a complete (including halo points) gathered copy of iV is collected into the temporary AttrVect variable workV (the length of workV is the larger of GlobalSegMap_GlobalStorage(GSMap) or GlobalSegMap_GlobalSize(GSMap)). The variable workV is segmented by process, and segments are copied into it by process, but ordered in the same order the segments appear in GSMap. Once workV is loaded, the data are copied segment-by-segment to their appropriate locations in the output AttrVect oV.

This module provides routines to perform reductions on
the AttrVect datatype. These reductions can either be the types
of operations supported by MPI (currently, summation, minimum and
maximum are available) that are applied either to all the attributes
(both integer and real), or specific reductions applicable only to the
real attributes of an AttrVect. This module provides services
for both local (i.e., one address space) and global (distributed)
reductions. The type of reduction is defined through use of one of
the public data members of this module:
