Function Documentation

void cps::MPISCU::CommsInit (   )

Initialises the MPI communications layer. This function finds the parameters relevant for the parallel decomposition of the lattice, sets up the communications layer and defines the grid topology. It also defines a root node (which is useful for IO) and opens logfiles (if required). Definition at line 413 of file sysfunc.C. References cps::Fopen(), cps::MPISCU::fprintf_all(), NDIM, cps::MPISCU::ParseCommsParam(), cps::MPISCU::printf_all(), and cps::MPISCU::RaiseError(). Referenced by cps::MPISCU::ReadSeedFile(), and cps::MPISCU::SCUGlobalSum().

void cps::MPISCU::RaiseError (  const char *  errstring  )

Reports an error. Prints an error message to stdout and causes the program to exit immediately with the value EXIT_FAILURE. Parameters: errstr  The messsage. Definition at line 645 of file sysfunc.C. Referenced by cps::MPISCU::CommsInit(), cps::MPISCU::MPITypeConv(), cps::MPISCU::ParseCommsParam(), cps::MPISCU::ReadSeedFile(), and cps::MPISCU::SCUGlobalSum().

void cps::MPISCU::RaiseError (  char *  errstr  )

Reports an error. Prints an error message to stdout and causes the program to exit immediately with the value EXIT_FAILURE. Parameters: errstr  The messsage. Definition at line 625 of file sysfunc.C.

void SCUCommsFinalize (  void   )

Definition at line 570 of file sysfunc.C.
