Structure defining a region.
The base address of the region
| SizeT SharedRegion_Entry::len |
The length of the region
Ths length of a region must be the same across all processors in the system.
The MultiProc id of the owner of the region
The owner id for a shared region must be the same across all processors in the system.
Whether the region is valid
Whether to perform cache operations for the region
If 'TRUE', a cache invalidate is performed before any read and a cache write back invalidate is performed after any write for the shared region. The cache operations are done for all caches. If 'FALSE', no cache operations are performed.
The cache line size of the region
The cache line size for a region must be the same across all processors in the system. It is used for structure alignment and padding.
Whether a heap is created for the region
If 'TRUE', a HeapMemMP instance is created with the size spanning the length of the shared region minus any memory that is reserved in the region. If 'FALSE', no heap is created in the shared region.
| String SharedRegion_Entry::name |
The name of the region.
The name must be in persistent memory. It is used for displaying in ROV.
