#define PARALLEL_GID_TAG_NAME   "GLOBAL_ID"

Global identifier for interface mesh.

Tag conventions for naming parallel things. Note this header file belongs in the main MOAB directory because even serial applications (e.g. partitioners) may write tags for use in parallel applications. An integer identifier common to the corresponding mesh entity instances on each processor for a mesh entity on the interface.

#define PARALLEL_PARTITION_TAG_NAME   "PARALLEL_PARTITION"

Tag on a meshset representing a parallel partition.

When the mesh is partitioned for use in a parallel environment, the each CPUs partition of the mesh is stored in a meshset with this tag. The value of the tag is an integer "part identifier".

Examples:
LoadPartial.cpp.

#define PARALLEL_PARTITIONING_TAG_NAME   "PARALLEL_MESH_PARTITIONING"

Tag that groups the set of parts/partitions that are a covering of the mesh.

This tag labels an entity set for which the child sets are part(ition)s that together are a single partitioning of the mesh. I.e. There should be no mesh entity that is contained in more than one child part(ition) set, and typically every mesh entity of the dimension used to partition the mesh is contained in exactly one of the child sets.

The data for this tag is a single integer value. The value of the tag is undefined.

#define PARALLEL_SHARED_HANDLE_TAG_NAME   "__PARALLEL_SHARED_HANDLE"

Tag storing the handle of a shared entity on the other proc.

This single-valued tag implies an entity is shared with one other proc

Referenced by get_sharing_processors(), print_partitioned_entities(), and moab::ParallelComm::sharedh_tag().

#define PARALLEL_SHARED_HANDLES_TAG_NAME   "__PARALLEL_SHARED_HANDLES"

Tag storing handles of a shared entity on other processors.

This multiple-valued tag implies an entity is shared with multiple other processors. Length of tag is application-dependent, and depends on what the maximum number of processors is which share an entity

Referenced by get_sharing_processors(), print_partitioned_entities(), and moab::ParallelComm::sharedhs_tag().

#define PARALLEL_SHARED_PROC_TAG_NAME   "__PARALLEL_SHARED_PROC"

Tag storing which other processor a given entity is shared with.

This single-valued tag implies an entity is shared with one other proc

#define PARALLEL_SHARED_PROCS_TAG_NAME   "__PARALLEL_SHARED_PROCS"

Tag storing which other processorS a given entity is shared with.

This multiple-valued tag implies an entity is shared with multiple other processors. Length of tag is application-dependent, and depends on what the maximum number of processors is which share an entity

#define PARALLEL_STATUS_TAG_NAME   "__PARALLEL_STATUS"

Tag storing parallel status (as bits in this tag)

This tag stores various aspects of parallel status in bits; see also #define's following, to be used in bit mask operations. If an entity is not shared with any other processors, the pstatus is 0, otherwise it's > 0

bit 0: !owned (0=owned, 1=not owned) bit 1: shared (0=not shared, 1=shared) bit 2: multishared (shared by > 2 procs; 0=not shared, 1=shared) bit 3: interface (0=not interface, 1=interface) bit 4: ghost (0=not ghost, 1=ghost)
