      Parallel IO: New collated file format
      
      When an OpenFOAM simulation runs in parallel, the data for decomposed fields and
      mesh(es) has historically been stored in multiple files within separate
      directories for each processor.  Processor directories are named 'processorN',
      where N is the processor number.
      
      This commit introduces an alternative "collated" file format where the data for
      each decomposed field (and mesh) is collated into a single file, which is
      written and read on the master processor.  The files are stored in a single
      directory named 'processors'.
      
      The new format produces significantly fewer files - one per field, instead of N
      per field.  For large parallel cases, this avoids the restriction on the number
      of open files imposed by the operating system limits.
      
      The file writing can be threaded allowing the simulation to continue running
      while the data is being written to file.  NFS (Network File System) is not
      needed when using the the collated format and additionally, there is an option
      to run without NFS with the original uncollated approach, known as
      "masterUncollated".
      
      The controls for the file handling are in the OptimisationSwitches of
      etc/controlDict:
      
      OptimisationSwitches
      {
          ...
      
          //- Parallel IO file handler
          //  uncollated (default), collated or masterUncollated
          fileHandler uncollated;
      
          //- collated: thread buffer size for queued file writes.
          //  If set to 0 or not sufficient for the file size threading is not used.
          //  Default: 2e9
          maxThreadFileBufferSize 2e9;
      
          //- masterUncollated: non-blocking buffer size.
          //  If the file exceeds this buffer size scheduled transfer is used.
          //  Default: 2e9
          maxMasterFileBufferSize 2e9;
      }
      
      When using the collated file handling, memory is allocated for the data in the
      thread.  maxThreadFileBufferSize sets the maximum size of memory in bytes that
      is allocated.  If the data exceeds this size, the write does not use threading.
      
      When using the masterUncollated file handling, non-blocking MPI communication
      requires a sufficiently large memory buffer on the master node.
      maxMasterFileBufferSize sets the maximum size in bytes of the buffer.  If the
      data exceeds this size, the system uses scheduled communication.
      
      The installation defaults for the fileHandler choice, maxThreadFileBufferSize
      and maxMasterFileBufferSize (set in etc/controlDict) can be over-ridden within
      the case controlDict file, like other parameters.  Additionally the fileHandler
      can be set by:
      - the "-fileHandler" command line argument;
      - a FOAM_FILEHANDLER environment variable.
      
      A foamFormatConvert utility allows users to convert files between the collated
      and uncollated formats, e.g.
          mpirun -np 2 foamFormatConvert -parallel -fileHandler uncollated
      
      An example case demonstrating the file handling methods is provided in:
      $FOAM_TUTORIALS/IO/fileHandling
      
      The work was undertaken by Mattijs Janssens, in collaboration with Henry Weller.

      listSwitches: moved from argList to debug · 5403e977
      Henry Weller authored and Andrew Heather's avatar Andrew Heather committed
      Initially the listSwitches functions depended directly on argList functionality
      but this has now been factored out so that the listSwitches functions are more
      general and require only debug functionality.

      ENH: default jobControl now under the '~/.OpenFOAM/jobControl' directory · af49eaf6
      Mark Olesen authored
      - this implies that jobControl is a user-resource for OpenFOAM.
        It was previously located under $WM_PROJECT_INST_DIR/jobControl,
        but few users will have write access there.
      
      - an unset FOAM_JOB_DIR variable is treated as "~/.OpenFOAM/jobControl",
        which can partially reduce environment clutter.
      
      - provide argList::noJobInfo() to conveniently suppress job-info on an
        individual basis for short-running utilities (eg, foamListTimes) to
        avoid unneeded clutter.

      BUG: resolve some decomposeParDict problems (issues #60, #265). · 52d0289e
      Mark Olesen authored
      - Cleanup/centralize handling of -decomposeParDict by relocating
        common code into argList. Ensures that all processes receive
        identical information about the -decomposeParDict opton.
      
      - Only use alternative decomposeParDict for simpleFoam/motorBike
        tutorial so that this will be included in the test loop for snappy.
      
      - Added Mattijs' fix for surfaceRedistributePar.

      simpleFoam: Added experimental "-postProcess" option · cc455173
      Henry Weller authored
          Executes application functionObjects to post-process existing results.
      
          If the "dict" argument is specified the functionObjectList is constructed
          from that dictionary otherwise the functionObjectList is constructed from
          the "functions" sub-dictionary of "system/controlDict"
      
          Multiple time-steps may be processed and the standard utility time
          controls are provided.
      
      This functionality is equivalent to execFlowFunctionObjects but in a
      more efficient and general manner and will be included in all the
      OpenFOAM solvers if it proves effective and maintainable.
      
      The command-line options available with the "-postProcess" option may be
      obtained by
      
      simpleFoam -help -postProcess
      
      Usage: simpleFoam [OPTIONS]
      options:
        -case <dir>       specify alternate case directory, default is the cwd
        -constant         include the 'constant/' dir in the times list
        -dict <file>      read control dictionary from specified location
        -latestTime       select the latest time
        -newTimes         select the new times
        -noFunctionObjects
                          do not execute functionObjects
        -noZero           exclude the '0/' dir from the times list, has precedence
                          over the -withZero option
        -parallel         run in parallel
        -postProcess      Execute functionObjects only
        -region <name>    specify alternative mesh region
