HPL_recv(3) HPL Library Functions HPL_recv(3) NAME HPL_recv - Receive a message. SYNOPSIS #include "hpl.h" int HPL_recv( double * RBUF, int RCOUNT, int SRC, int RTAG, MPI_Comm COMM ); DESCRIPTION HPL_recv is a simple wrapper around MPI_Recv. Its main purpose is to allow for some experimentation / tuning of this simple routine. Success- ful completion is indicated by the returned error code HPL_SUCCESS. In the case of messages of length less than or equal to zero, this function returns immediately. ARGUMENTS RBUF (local output) double * On entry, RBUF specifies the starting address of buffer to be re- ceived. RCOUNT (local input) int On entry, RCOUNT specifies the number of double precision en- tries in RBUF. RCOUNT must be at least zero. SRC (local input) int On entry, SRC specifies the rank of the sending process in the communication space defined by COMM. RTAG (local input) int On entry, STAG specifies the message tag to be used for this com- munication operation. COMM (local input) MPI_Comm The MPI communicator identifying the communication space.
