Field Detail

BITS_PER_OBJECT

private final int BITS_PER_OBJECT

size

private final int size

offsetActual

private final int offsetActual

offsetSpecified

private final int offsetSpecified

offsetReadOnly

private final int offsetReadOnly

rank

private transient int rank

orig

private final EnlargingBooleanArray2D orig

copy

private transient EnlargingBooleanArray2D copy

modifiedIDs

private transient IntOpenHashSet modifiedIDs

sharedIDs

private transient IntOpenHashSet sharedIDs

Set of indentifiers being shared among the current rank and other ranks. An object is considered shared, if it is present in more than one subspace of this PartitionedObjectSpace and it is not marked read-only.

sharedCnt

private transient int[] sharedCnt

Counts the number of non-read-only objects that are shared between the local rank and each other rank. If this counter reaches zero for some rank, there is no need for communication with this rank during a collective update.
