SEND(3PVM) PVM Version 3.4 SEND(3PVM)

pvm_send - Immediately sends the data in the active message buffer.

C	int info = pvm_send( int tid, int msgtag )
 
Fortran call pvmfsend( tid, msgtag, info )

tid
Integer task identifier of destination process.
 
msgtag
Integer message tag supplied by the user. msgtag should be >= 0.
 
info
Integer status code returned by the routine.

The routine pvm_send sends a message stored in the active send buffer to the PVM process identified by tid. msgtag is used to label the content of the message. If pvm_send is successful, info will be 0. If some error occurs then info will be < 0.
The pvm_send routine is asynchronous. Computation on the sending processor resumes as soon as the message is safely on its way to the receiving processor. This is in contrast to synchronous communication, during which computation on the sending processor halts until the matching receive is executed by the receiving processor.
The PVM model guarantees the following about message order. If task 1 sends message A to task 2, then task 1 sends message B to task 2, message A will arrive at task 2 before message B. Moreover, if both messages arrive before task 2 does a receive, then a wildcard receive will always return message A.
Terminating a PVM task immediately after sending a message or messages from it may result in those messages being lost. To be sure, always call pvm_exit() before stopping.

C:
	info = pvm_initsend( PvmDataDefault );
	info = pvm_pkint( array, 10, 1 );
	msgtag = 3 ;
	info = pvm_send( tid, msgtag );
Fortran: CALL PVMFINITSEND(PVMRAW, INFO) CALL PVMFPACK( REAL8, DATA, 100, 1, INFO ) CALL PVMFSEND( TID, 3, INFO )

These error conditions can be returned by pvm_send
PvmBadParam
giving an invalid tid or a msgtag.
PvmSysErr
pvmd not responding.
PvmNoBuf
no active send buffer. Try pvm_initsend() before send.
