Operation Hurricane Operation Hurricane Operation Hurricane was the test of the first UK atomic device, on 3 October 1952. A plutonium implosion device was detonated in the lagoon in the Monte Bello Islands in Western Australia. With the success of Operation Hurricane, Britain became the third nuclear power after the United States and the Soviet Union. During the Second World War, Britain commenced a nuclear weapons project, known as Tube Alloys, but the 1943 Quebec Agreement merged it with the American Manhattan Project. Several key British scientists worked as part of the British contribution to the Manhattan Project, but after the war
Test-and-set overhead for TSL is next to nothing since only one lock is required. Uncontended latency is also low since only one atomic instruction and branch are needed. Test-and-set In computer science, the test-and-set instruction is an instruction used to write 1 (set) to a memory location and return its old value as a single atomic (i.e., non-interruptible) operation. If multiple processes may access the same memory location, and if a process is currently performing a test-and-set, no other process may begin another test-and-set until the first process's test-and-set is finished. A CPU may use a test-and-set instruction offered by another
