<p>A method and apparatus for providing a resource lockout mechanism in a shared memory, multiprocessor system (10) that is capable of performing both a read and write operation during the same memory operation. The load and flag instruction (load f) of the present invention can execute a read operation, followed by a write operation of a preselected flag value to the same memory location during the same memory operation. The load and flag instruction is particularly useful as a resource lockout mechanism for use in Monte Carlo applications.</p> |
