Detailed Description

This handler encapsulates the primary definition of MPCI packets. This handler defines the part of the packet that is common to all remote operations.

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.
