Function Documentation

void SafeMPI::Attach_buffer ( void *  buffer, int  size  )

inline

Set buffer for Bsend .

Parameters

buffer	The buffer to be used by Bsend
size	The size of the buffer in Bytes

References MADNESS_MPI_TEST, and MPI_Buffer_attach().

int SafeMPI::Detach_buffer ( void *&  buffer )

inline

Unset the Bsend buffer.

Parameters

[out]

buffer

The buffer that was used by Bsend

int SafeMPI::Finalize ( )

inline

Analogous to MPI_Finalize.

This returns status rather than throw an exception upon failure because this is a "destructor", and throwing from destructors is evil.

Returns

0 if successful, nonzero otherwise (see MPI_Finalize() for the return codes).

void SafeMPI::Init ( int &  argc, char **&  argv  )

inline

Analogous to MPI_Init.

Parameters

argc	The number of arguments in argv
argv	The vector of command-line arguments

Referenced by Init(), main(), testing::internal::NativeArray< Element >::NativeArray(), and testing::internal::RE::RE().

void SafeMPI::Init ( )

inline

Analogous to MPI_Init.

References Init().

int SafeMPI::Init_thread ( int &  argc, char **&  argv, int  requested  )

inline

Analogous to MPI_Init_thread.

Parameters

argc	the number of arguments in argv
argv	the vector of command-line arguments
requested	the desired thread level

Returns

provided thread level

int SafeMPI::Init_thread ( int  requested )

inline

Analogous to MPI_Init_thread.

Parameters

requested

the desired thread level

Returns

provided thread level

bool SafeMPI::Is_finalized ( )

inline

Check MPI finalization status.

Returns

true if MPI has been finalized, false otherwise.

References MPI_Finalized().

bool SafeMPI::Is_initialized ( )

inline

Check MPI initialization status.

Returns

int SafeMPI::Query_thread ( )

inline

Analogous to MPI_Query_thread.

Returns

the MPI thread level provided by SafeMPI::Init_thread()

double SafeMPI::Wtime ( )

inline

Wall time.

Returns

The current wall time
