Improvements to existing functionality
--------------------------------------
- MPI is initialised without thread support if it is not needed e.g. uncollated
- Use native c++11 threading; avoids problem with static destruction order.
- etc/cellModels now only read if needed.
- etc/controlDict can now be read from the environment variable FOAM_CONTROLDICT
- Uniform files (e.g. '0/uniform/time') are now read only once on the master only
(with the masterUncollated or collated file handlers)
- collated format writes to 'processorsNNN' instead of 'processors'. The file
format is unchanged.
- Thread buffer and file buffer size are no longer limited to 2Gb.
The global controlDict file contains parameters for file handling. Under some
circumstances, e.g. running in parallel on a system without NFS, the user may
need to set some parameters, e.g. fileHandler, before the global controlDict
file is read from file. To support this, OpenFOAM now allows the global
controlDict to be read as a string set to the FOAM_CONTROLDICT environment
variable.
The FOAM_CONTROLDICT environment variable can be set to the content the global
controlDict file, e.g. from a sh/bash shell:
export FOAM_CONTROLDICT=$(foamDictionary $FOAM_ETC/controlDict)
FOAM_CONTROLDICT can then be passed to mpirun using the -x option, e.g.:
mpirun -np 2 -x FOAM_CONTROLDICT simpleFoam -parallel
Note that while this avoids the need for NFS to read the OpenFOAM configuration
the executable still needs to load shared libraries which must either be copied
locally or available via NFS or equivalent.
New: Multiple IO ranks
----------------------
The masterUncollated and collated fileHandlers can now use multiple ranks for
writing e.g.:
mpirun -np 6 simpleFoam -parallel -ioRanks '(0 3)'
In this example ranks 0 ('processor0') and 3 ('processor3') now handle all the
I/O. Rank 0 handles 0,1,2 and rank 3 handles 3,4,5. The set of IO ranks should always
include 0 as first element and be sorted in increasing order.
The collated fileHandler uses the directory naming processorsNNN_XXX-YYY where
NNN is the total number of processors and XXX and YYY are first and last
processor in the rank, e.g. in above example the directories would be
processors6_0-2
processors6_3-5
and each of the collated files in these contains data of the local ranks
only. The same naming also applies when e.g. running decomposePar:
decomposePar -fileHandler collated -ioRanks '(0 3)'
New: Distributed data
---------------------
The individual root directories can be placed on different hosts with different
paths if necessary. In the current framework it is necessary to specify the
root per slave process but this has been simplified with the option of specifying
the root per host with the -hostRoots command line option:
mpirun -np 6 simpleFoam -parallel -ioRanks '(0 3)' \
-hostRoots '("machineA" "/tmp/" "machineB" "/tmp")'
The hostRoots option is followed by a list of machine name + root directory, the
machine name can contain regular expressions.
New: hostCollated
-----------------
The new hostCollated fileHandler automatically sets the 'ioRanks' according to
the host name with the lowest rank e.g. to run simpleFoam on 6 processors with
ranks 0-2 on machineA and ranks 3-5 on machineB with the machines specified in
the hostfile:
mpirun -np 6 --hostfile hostfile simpleFoam -parallel -fileHandler hostCollated
This is equivalent to
mpirun -np 6 --hostfile hostfile simpleFoam -parallel -fileHandler collated -ioRanks '(0 3)'
This example will write directories:
processors6_0-2/
processors6_3-5/
A typical example would use distributed data e.g. no two nodes, machineA and
machineB, each with three processes:
decomposePar -fileHandler collated -case cavity
# Copy case (constant/*, system/*, processors6/) to master:
rsync -a cavity machineA:/tmp/
# Create root on slave:
ssh machineB mkdir -p /tmp/cavity
# Run
mpirun --hostfile hostfile icoFoam \
-case /tmp/cavity -parallel -fileHandler hostCollated \
-hostRoots '("machineA" "/tmp" "machineB" "/tmp")'

Description
|
|
Automatically decomposes a mesh and fields of a case for parallel
|
|
execution of OpenFOAM.
|
|
|
|
Usage
|
|
\b decomposePar [OPTION]
|
|
|
|
Options:
|
|
- \par -cellDist
|
|
Write the cell distribution as a labelList, for use with 'manual'
|
|
decomposition method or as a volScalarField for post-processing.
|
|
|
|
- \par -region \<regionName\>
|
|
Decompose named region. Does not check for existence of processor*.
|
|
|
|
- \par -allRegions
|
|
Decompose all regions in regionProperties. Does not check for
|
|
existence of processor*.
|
|
|
|
- \par -copyZero
|
|
Copy \a 0 directory to processor* rather than decompose the fields.
|
|
|
|
- \par -copyUniform
|
|
Copy any \a uniform directories too.
|
|
|
|
- \par -constant
|
|
|
|
- \par -time xxx:yyy
|
|
Override controlDict settings and decompose selected times. Does not
|
|
re-decompose the mesh i.e. does not handle moving mesh or changing
|
|
mesh cases.
|
|
|
|
- \par -fields
|
|
Use existing geometry decomposition and convert fields only.
|
|
|
|
- \par -noSets
|
|
Skip decomposing cellSets, faceSets, pointSets.
|
|
|
|
- \par -force
|
|
Remove any existing \a processor subdirectories before decomposing the
|
|
geometry.
|
|
|
|
- \par -ifRequired
|
|
Only decompose the geometry if the number of domains has changed from a
|
|
previous decomposition. No \a processor subdirectories will be removed
|
|
unless the \a -force option is also specified. This option can be used
|
|
to avoid redundant geometry decomposition (eg, in scripts), but should
|
|
be used with caution when the underlying (serial) geometry or the
|
|
decomposition method etc. have been changed between decompositions.
