Abstract
A technique is provided for monitoring a value without repeated storage access. A processing circuit processes an instruction of a program that specifies a memory address of a memory location to be monitored. The processing circuit configures a monitor station for monitoring the memory location. The memory location includes a state descriptor for the program. The processing circuit receives a cross-invalidate request from a memory controller. The cross-invalidate request indicates to the monitor station that content of the memory location has been changed by another processing circuit.
