maloc_base.h
The base (or foundation) header for MALOC.
vsys.h
The primary header for VSYS. (Virtual SYStem utilities library.)
Vcom_rank
int Vcom_rank(Vcom *thee)
Get the ID of the local PE
Vcom_resize
int Vcom_resize(Vcom *thee, int newsize)
Resize (shrink) the communications group to include only newsize number of processors....
Vcom_ctor2
int Vcom_ctor2(Vcom *thee, int commtype)
Construct the communications object. This routine sets up data members of class and initializes MPI....
Vcom_size
int Vcom_size(Vcom *thee)
Get the number of PEs in communicator.
Vcom_reduce
int Vcom_reduce(Vcom *thee, void *sendbuf, void *recvbuf, int length, int type, int op)
Perform a reduction of the data across all processors. This is equivalent (and in the case of MPI is ...
Vcom_ctor
Vcom * Vcom_ctor(int commtype)
Construct the communications object. This routine sets up data members of class and initializes MPI.
Vcom_init
int Vcom_init(int *argc, char ***argv)
The Vmp initializer.
Vcom_finalize
int Vcom_finalize(void)
The Vmp finalizer.
Vcom_barr
int Vcom_barr(Vcom *thee)
Synchronization barrier.
Vcom_dtor
void Vcom_dtor(Vcom **thee)
Destroy the communications object.
Vcom_recv
int Vcom_recv(Vcom *thee, int src, void *buf, int len, int type, int block)
Receive a (character) buffer. The blocking flag is present, but not used. All receives are assumed ...
Vcom_getCount
int Vcom_getCount(Vcom *thee, int src, int *length, int type)
Perform a blocking probe to get the length (in number of items of specified type) of an incoming mess...
Vcom_send
int Vcom_send(Vcom *thee, int des, void *buf, int len, int type, int block)
Send a buffer. Returns 1 on success.
Vcom_dtor2
void Vcom_dtor2(Vcom *thee)
Destroy the communications object. This is broken into two parts to be callable from FORTRAN.
