Detailed Description

This group contains the Multiprocessing (MP) Packet Handler implementation.

This handler encapsulates the primary definition of MPCI packets. This handler defines the part of the packet that is common to all remote operations. It defines the basic packet and provides mechanisms to utilize packets based on this prefix. Packets are the fundamental basis for messages passed between nodes in an MP system.

Macro Definition Documentation

MP_PACKET_CLASSES_FIRST

#define MP_PACKET_CLASSES_FIRST   MP_PACKET_MPCI_INTERNAL

This constant defines the first entry in the MP_packet_Classes enumeration.

MP_PACKET_CLASSES_LAST

#define MP_PACKET_CLASSES_LAST   MP_PACKET_SIGNAL

This constant defines the last entry in the MP_packet_Classes enumeration.

MP_PACKET_MINIMUM_PACKET_SIZE

#define MP_PACKET_MINIMUM_PACKET_SIZE   64

An MPCI must support packets of at least this size.

MP_PACKET_MINIMUN_HETERO_CONVERSION

#define MP_PACKET_MINIMUN_HETERO_CONVERSION    ( sizeof( MP_packet_Prefix ) / sizeof( uint32_t ) )

The following constant defines the number of uint32_t's in a packet which must be converted to native format in a heterogeneous system. In packets longer than MP_PACKET_MINIMUN_HETERO_CONVERSION uint32_t's, some of the "extra" data may a user message buffer which is not automatically endian swapped.

Enumeration Type Documentation

MP_packet_Classes

enum MP_packet_Classes

The following enumerated type defines the packet classes.

Note

In general, each class corresponds to a manager which supports global operations. Each manager defines the set of supported operations.
