2.6 Broadcasting Messages

void CmiSyncBroadcast(unsigned int size, void *msg)
Sends msg of length size bytes to all processors excluding the processor on which the caller resides.

void CmiSyncNodeBroadcast(unsigned int size, void *msg)
Sends msg of length size bytes to all nodes excluding the node on which the caller resides.

void CmiSyncBroadcastAndFree(unsigned int size, void *msg)
Sends msg of length size bytes to all processors excluding the processor on which the caller resides. Uses CmiFree to deallocate the message buffer for msg when the broadcast completes. Therefore msg must point to a buffer allocated with CmiAlloc.

void CmiSyncNodeBroadcastAndFree(unsigned int size, void *msg)
Sends msg of length size bytes to all nodes excluding the node on which the caller resides. Uses CmiFree to deallocate the message buffer for msg when the broadcast completes. Therefore msg must point to a buffer allocated with CmiAlloc.

void CmiSyncBroadcastAll(unsigned int size, void *msg)
Sends msg of length size bytes to all processors including the processor on which the caller resides. This function does not free the message buffer for msg.

void CmiSyncNodeBroadcastAll(unsigned int size, void *msg)
Sends msg of length size bytes to all nodes including the node on which the caller resides. This function does not free the message buffer for msg.

void CmiSyncBroadcastAllAndFree(unsigned int size, void *msg)
Sends msg of length size bytes to all processors including the processor on which the caller resides. This function frees the message buffer for msg before returning, so msg must point to a dynamically allocated buffer.

void CmiSyncNodeBroadcastAllAndFree(unsigned int size, void *msg)
Sends msg of length size bytes to all nodes including the node on which the caller resides. This function frees the message buffer for msg before returning, so msg must point to a dynamically allocated buffer.

CmiCommHandle CmiAsyncBroadcast(unsigned int size, void *msg)
Initiates asynchronous broadcast of message msg of length size bytes to all processors excluding the processor on which the caller resides. It returns a communication handle which could be used to check the status of this send using CmiAsyncMsgSent. If the returned communication handle is 0, message buffer can be reused immediately, thus saving a call to CmiAsyncMsgSent. msg should not be overwritten or freed before the communication is complete.

CmiCommHandle CmiAsyncNodeBroadcast(unsigned int size, void *msg)
Initiates asynchronous broadcast of message msg of length size bytes to all nodes excluding the node on which the caller resides. It returns a communication handle which could be used to check the status of this send using CmiAsyncMsgSent. If the returned communication handle is 0, message buffer can be reused immediately, thus saving a call to CmiAsyncMsgSent. msg should not be overwritten or freed before the communication is complete.

CmiCommHandle CmiAsyncBroadcastAll(unsigned int size, void *msg)
Initiates asynchronous broadcast of message msg of length size bytes to all processors including the processor on which the caller resides. It returns a communication handle which could be used to check the status of this send using CmiAsyncMsgSent. If the returned communication handle is 0, message buffer can be reused immediately, thus saving a call to CmiAsyncMsgSent. msg should not be overwritten or freed before the communication is complete.

CmiCommHandle CmiAsyncNodeBroadcastAll(unsigned int size, void *msg)

It returns a communication handle which could be used to check the status of this send using CmiAsyncMsgSent. If the returned communication handle is 0, message buffer can be reused immediately, thus saving a call to CmiAsyncMsgSent. msg should not be overwritten or freed before the communication is complete.
