- when reading, detect all clouds on all processors and uses this when
reading fields. Similarly, when writing it uses writeOnProc to skip
clouds that are empty on any particular processor.

- was previously limited to 'char' whereas gatherv/scatterv
already supported various integer and float types
STYLE: rebundle allToAll declarations with macros
ENH: provide a version of allToAllConsensus returning the Map
- simplifies use and avoids ambiguities in the send/recv parameters
- the Map version will now also transmit zero value data if they exist
in the Map. Unlike the List version, zero values are not necessary to
signal connectivity with a Map.
COMP: forwarding template parameters for NBX routines
ENH: consolidate PstreamBuffers size exchange options
- had a variety of nearly identical backends for all-to-all,
gather/scatter. Now combined internally with a dispatch enumeration
which provides better control over which size exchange algorithm
is used.
DEFEATURE: remove experimental full-NBX PstreamBuffers variant
- no advantages seen compared to the hybrid NBX/PEX approach.
Removal reduces some code cruft.
DEFEATURE: remove experimental "double non-blocking" NBX version
- the idea was to avoid blocking receives for very large data transfers,
but that is usually better accomplished with a hybrid NBX/PEX approach
like PstreamBuffers allows
- provide a globalIndex::calcOffsets() taking an indirect list, which
enables convenient offsets calculation from a variety of inputs.
- new CompactListList unpack variant: copy_unpack()
The copy_unpack() works somewhat like std::copy() in that it writes
the generated sublists to iterator positions, which makes this
type of code possible:
CompactListList<label> compact = ...;
DynamicList<face> extracted;
compact.copy_unpack<face>
(
std::back_inserter(extracted),
labelRange(4, 10)
);
-and-
const label nOldFaces = allFaces.size();
allFaces.resize(allFaces + nNewFaces);
auto iter = allFaces.begin(nOldFaces);
iter = compact.copy_unpack<face>(iter, /* selection 1 */);
...
iter = compact.copy_unpack<face>(iter, /* selection 2 */);
ENH: globalIndex resize()
- can be used to shrink or grow the offsets table.
Any extension of the offsets table corresponds to 'slots'
with 0 local size.
- report location with previous good offset and the new count that
would cause overflow. Simpler to report and the (very long) list
of input sizes is not particularly useful for diagnostics either.
ENH: add globalIndex comparison operators
- for outputting lists of globalIndex
- allows construction of string tokens holding character content.
For example, data that has been serialized and buffered and that
now needs to be written or sent to another process.
- the default returns -1 (ie, not found/available). This is overridden
by processorCyclicPolyPatch to actually perform a search
COMP: explicitly define polyMesh::writeObject in the header
- currently no special treatment, but allows future adjustments
without affecting the header.
- extends the enumeration (NO_REGISTER, REGISTER, LEGACY_REGISTER).
Can be used to tweak registration preference where required and
potentially (TDB) to define a different default value in the future
- CompactListList::size() corresponds to the number of sub-lists
whereas globalIndex::size() corresponds to the totalSize().
This difference can lead to potential coding errors when switching
between pure addressing (eg globalIndex) and addressing with content
(eg, CompactListList).
Within the source tree, there are no longer any occurances of
globalIndex::size() but it is nonetheless unsafe to change its
meaning now. Instead provide a commonly named length() method that
corresponds to the natural length: ie, the number of offsets minus 1
(with guards).
- add CompactListList::writeMatrix for writing the compact contents
in an unpacked form (eg, for debugging) without actually needing to
unpack into storage.
- provide globalIndex::whichProcID() two-parameter version
with myProcNo as the first argument.
Symmetric with isLocal etc, useful when using a communicator
that is not worldComm.
- avoids clutter of argList::envGlobalPath() ...
ENH: allow temporary overwriting of output writeFormat
- allows switching for particular output routines
COMP: explicitly use TimePaths methods with Time
- this simplifies any overloading done at a later stage
- remnant was left in the NBX implementation for Map<Type>.
Still not entirely certain which vendors/versions handle message
probe/recv properly, but using the "regular" probe and recv is OK
since everything is without threaded race conditions.
STYLE: adjust file extension of UPstreamWrapping templates
- avoids it being exposed via lnInclude
- this makes it easier to split creation into a two-stage process
as required
- extend handling for polyBoundaryMeshEntries, faBoundaryMeshEntries
with more functionality. Ensure that these are never registered.
ENH: addition writeEntry methods for polyBoundaryMesh
- simplifies streaming and collating into other files
ENH: polyMesh rereading - update owner/neighbour header information
- this avoids accidentally reading the "cells" file if the mesh has
been created with NO_READ and then updated
STYLE: less vertical space when outputting empty PtrList
- combined most of the unweighted and weighted decomposition routines
such that an empty weight field is treated as uniform weighting.
This allows default parameters and cuts down on the number of
decompose methods.
- for topology-driven decomposition, it is now possible to pass in the
owner/neighbour connectivity as a CompactListList directly instead
of first creating a labelListList (which was internally repacked into
a CompactListList in many cases).
However, multiLevelDecomp still uses unpacking (to avoid a larger
reworking of code).
- support direct creation of some methods (eg, random, scotch etc)
without a dictionary
- fix incorrect neighbour face weighting (fixes#3019)
ENH: relocate calcCellCells from decompositionMethod to globalMeshData
- makes it more universally available
- usually only need big/little defines (which are now in the Fwd)
and rarely need byte-swapping.
Provide endian.H compatibility include, but foamEndianFwd.H or
foamEndian.H to avoid potential name clashes.
- The pTraits_cmptType returns the data type of 'cmptType' (for
arithmetic and VectorSpace types) or is simply a pass-through.
This can be combined with the pTraits_nComponents for casting.
For example,
function
(
reinterpret_cast<pTraits_cmptType<Type>::type*>(buf.data()),
(buf.size()/pTraits_nComponents<Type>::value)
);
ENH: extend Foam::identityOp so support array indexing (pass-through)
