Abstract:
A disjoint instruction for accessing operands in memory while executing in a processor of a plurality of processes interrogates a state indicator settable by other processors to determine if the disjoint instruction accessed the operands without an intervening store operation from another processor to the operand. A condition code is set based on the state indicator.
