Detailed Description

fileOperations that performs all file operations on the master processor. Requires the calls to be parallel synchronised!

Limitations

  • no /processor in filename
  • no /uniform/ in the filename

The main logic is in ::filePath which returns a

  • same path on all processors. This can either be a global file (system/controlDict, processorXXX/0/uniform/) or a collated file (processors/0/p)
  • same path on all processors of the local communicator (processors4_0-1/0/p)
  • different path on all processors (processor0/0/p)

system/controlDict: filePath worldmaster: <globalRoot>/system/controlDict localmaster: ,, slave : ,,

processor0/uniform/time filePath worldmaster: <globalRoot>/processorXXX/uniform/time localmaster: ,, slave : ,,
