int MPI_Alloc_mem (MPI_Aint size, MPI_Info info, void
*baseptr)
|
MPI_Aint size | Size of memory to be allocated in byte |
MPI_Info info | Usage depends on implementation; only the value 0 must be supported |
void* baseptr | Pointer to the allocated memory |
|
int MPI_Put (void *origin_addr, int origin_count, MPI_Datatype origin_datatype, int target_rank, |
MPI Aint target_disp, int target_count, MPI Datatype_target datatype, MPI_Win win)
|
origin_* | Defines which data shall be sent to the target node |
target_* | Defines where the data are to be sent: the node (by rank), in which local memory address (target_disp) and the amount of data |
win | Defines the memory window on target |
|
int MPI_Get (void *origin_addr, int origin_count, MPI_Datatype origin_datatype, int target_rank, |
MPI_Aint target_disp, int target_count, MPI_Datatype target_datatype, MPI_Win win)
|
origin_* | Defines where the data which are read from target shall be stored |
target_* | Defines which data shall be read: from which node (by rank), from which local memory address (target_disp), and the amount of data |
win | Defines the memory window on target |
|
int MPI_Free_mem(void *base) |
void *base | Pointer to the memory that was allocated with MPI_Alloc_mem |
