METHODS AND APPARATUS TO IMPLEMENT PARALLEL TRANSACTIONS

The present disclosure describes a unique way for each of multiple processes to operate in parallel using (e.g., reading, modifying, and writing to) the same shared data without causing corruption to the shared data. For example, each of multiple processes utilizes current and past data values associated with a global counter or clock for purposes of determining whether any shared variables used to produce a respective transaction outcome were modified (by another process) when executing a respective transaction. If a respective process detects that shared data used by respective process was modified during a transaction, the process can abort and retry the transaction rather than cause data corruption by storing locally maintained results associated with the transaction to a globally shared data space.
