int reportMPIStats (  ) 

int procID (  ) 

local process ID

Returns the ID of the locally running process in the range 0 <= procID() < numProc(). This has no relation to the operating system pid. There is always a procID() == 0.

Referenced by blockWriteBufferToFile(), CHprocID(), gatherBoxesAndOffsets(), MergeSolver< T >::solve(), and write().

int CHprocID (  )  [inline]

References procID().

unsigned int numProc (  ) 

number of parallel processes

Returns the number of parallel processes running. Always returns at least 1.

Referenced by gatherBoxesAndOffsets(), and getOffsets().

void barrier ( void   )  [inline]

all ranks wait here to sync-up

All MPI ranks wait here to sync-up. Calls MPI_Barrier(comm)

void broadcast ( T &  a_inAndOut,

) [inline]

broadcast to every process

Broadcasts a_inAndOut to every process from process number a_src. It is an error if a_src < 0 or a_src >= numProc(). \

T must have have the following functions: \

int linearSize<T>(const T& inputT); \ void linearIn<T>(T& a_outputT, const void* const inBuf); \ void linearOut<T>(void* a_outBuf, const T& inputT); \
