- The Apple SIP (System Integrity Protection) clears environment
variables, which affects the behaviour of dynamic library loading
(the DYLD_LIBRARY_PATH env variable).
OpenFOAM shadows this variable as FOAM_LD_LIBRARY_PATH, which has
been used to restore DYLD_LIBRARY_PATH (eg, in RunFunctions script).
However, this solution is not quite complete, as it
(a) requires sourcing of RunFunctions file,
(b) additional errors appear depending on a user workflow.
This changeset alleviates the problem by also iterating through
paths stored in the shadow variable when loading dynamic libraries
(if the DYLD_LIBRARY_PATH is empty).
- with C++11, static constexpr variables apparently also require
definition in a translation unit and not just as inlined quantities.
Mostly not an issue, however gcc with -O0 does not do the inlining
and thus actually requires them to be defined in a translation unit
as well.
These variables were provided for symmetry with worldComm, but only
used in low-level internal code. Changing to inlined functions
solves the linkage issue and also aligns with the commWorld()
function naming.
Mnemonics:
MPI_COMM_SELF => UPstream::commSelf()
overall MPI_COMM_WORLD => UPstream::commGlobal(), sometimes commWorld()
local COMM_WORLD => UPstream::commWorld()
- useful when speculative receives have been initiated but are no
longer required.
Combines MPI_Cancel() + MPI_Request_free() for consistent resource
management. Currently no feedback provided if the request was
satisfied by a completed send/recv or by cancellation (can be added
later if required).
- primarily relevant for finite-area meshes, in which case they can be
considered to be an additional, detailed diagnositic that is
normally not needed (clutters the file system).
Writing can be enabled with the `-write-edges` option.
- 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
