- enable 'faceZones' support.
- enable 'writeFile' support to better control file output.
- rename 'PatchPostProcessing' as 'ParticlePostProcessing' for better clarity.
- fix#1808
- enable 'faceZone' support.
- introduce 'cloudFunctionObjectTools' to simplify collection of particle info
on patches or face zones.
- enable 'writeFile' support to better control file output.
- rename 'PatchParticleHistogram' as 'ParticleHistogram' for better clarity.
- extend the loadOrCreateMesh functionality to work in conjunction
with file handlers. This allows selective loading of the mesh parts
without the ugly workaround of writing zero-sized meshes to disk and
then reading them back.

- fatten the interface to continue allowing write control with a bool
or with a dedicated file handler. This may slim down in the future.

- use local function for the decision making, whether worldComm or a
dedicated communicator is needed (and which sibling ranks are
involved)

- accept plain lists (space or comma separated) as well as the
traditional OpenFOAM lists. This simplifies argument handling
with job scripts.
For example,
simpleFoam -ioRanks 0,4,8 ...
vs
simpleFoam -ioRanks '(0 4 8)' ...
It is also possible to select the IO ranks on a per-host basis:
simpleFoam -ioRanks host ...
- expose rank/subrank handling as static fileOperation methods
- previously checked on destruction, but it is robuster to check for a
locally defined communicator during construction
- add InfoProxy output for fileOperation
ENH: add fileOperation::storeComm()
- transfers management of the communicator from external to internal.
Use with caution
- for special cases it can simplify sharing of processor communication
patterns, but no visible change for most code.
- make fileHandler communicator modifiable (mutable), for special
cases. The changes from 9711b7f1b9 now make this safer to do.
Continue to support legacy global function using an autoPtr:
autoPtr<fileOperation> Foam::fileHandler(autoPtr<fileOperation>&&);
However, new code using refPtr uses the following static method since
swapping out file handlers is an infrequent operation that should
also stand out a bit more.
fileOperation::fileHandler(...);
- consolidate file synchronization checks in dynamicCode
STYLE: report missing library on master only (not every rank)
- avoid flooding the output with messages

- avoid explicit isFile() check in favour of a lazy-read.
With redistributePar + fileHandler, for example, it is possible that
the master processor finds file but not the subprocs
ENH: lazy reading of tetBasePtIs
- delay reading until needed

- added UPstream::allGatherValues() with a direct call to MPI_Allgather.
This enables possible benefit from a variety of internal algorithms
and simplifies the caller
Old:
labelList nPerProc
(
UPstream::listGatherValues<label>(patch_.size(), myComm)
);
Pstream::broadcast(nPerProc, myComm);
New:
const labelList nPerProc
(
UPstream::allGatherValues<label>(patch_.size(), myComm)
);
- Pstream::allGatherList uses MPI_Allgather for contiguous values
instead of the hand-rolled tree walking involved with
gatherList/scatterList.
-
- simplified the calling parameters for mpiGather/mpiScatter.
Since send/recv data types are identical, the send/recv count
is also always identical. Eliminates the possibility of any
discrepancies.
Since this is a low-level call, it does not affect much code.
Currently just Foam::profilingPstream and a UPstream internal.
BUG: call to MPI_Allgather had hard-coded MPI_BYTE (not the data type)
- a latent bug since it is currently only passed char data anyhow
UPstream::allocateCommunicator
- with contiguous sub-procs. Simpler, more compact handling, ranks
are guaranteed to be monotonic
UPstream::commWorld(label)
- ignore placeholder values, prevents accidental negative values
- make communicator non-optional for UPstream::broadcast(), which
means it has three mandatory parameters and thus always fully
disambiguated from Pstream::broadcast().
ENH: relax size checking on gatherList/scatterList
- only fatal if the List size is less than nProcs.
Can silent ignore any trailing elements: they will be untouched.
- calling the mixed BC dictionary construct with NO_READ leaves the
fields properly sized, but not initialised.
ENH: add mixed BC constructor zero initialise
- sometimes the last commit is not enough information about
the tested state (especially with extensive rebasing).
Also provide the short context of some previous commits.
- this refinement of commit 81807646ca makes these methods
consistent with other objects/containers.
The 'unsigned char' access is still available via cdata()
- extend toc/sortedToc wrappers to bitSet and labelHashSet to allow
use of BitOps::toc(...) in templated code
- size_data() method to return the number of addressed integer blocks
similar to size_bytes() does, but for int instead of char.
- use typeHeaderOk<regIOobject>(false) for some generic file existence
checks. Often had something like labelIOField as a placeholder, but
that may be construed to have a particular something.
- ensures that read failures can be properly detected
COMP: include refPtr.H instead of autoPtr.H in IOobject.H
- ensures inclusion of autoPtr/refPtr/tmp/stdFoam
ENH: add IOobject::resetHeader() method
- when re-using an IOobject for repeated read operations it enforces
resetting of headerClassName, scalar/label sizes etc prior to
reading. Permits convenient resetting of the name too (optional).
Example,
IOobject rio("none", ..., IOobject::LAZY_READ);
rio.resetHeader("U")
if (returnReduceOr(rio.typeHeaderOk<volVectorField>(false)))
...
io.resetHeader("p")
if (returnReduceOr(rio.typeHeaderOk<volScalarField>(false)))
...
