Asynchronous release operations in a multiprocessor system

Abstract

Various embodiments include techniques for performing memory synchronization operations between processors in a multiprocessor computing system. A first processor transfers data by issuing memory operations to store the data to a shared memory. The first processor issues an asynchronous release operation to a load store unit. In response, the load store unit issues a memory synchronization operation to ensure that the data associated with the memory operations is visible in the shared memory. While the asynchronous release operation is pending, the first processor is able to issue further instructions and perform other operations. When the data associated with the memory operations is visible in the shared memory, the memory synchronization operation completes and the load store unit writes a flag to a separate memory location. Upon detecting that the flag has been written, a second thread, and/or other threads, can reliably read the data stored in the shared memory.
