Abstract

A computing device initiates a transaction, corresponding to an application, which includes operations for accessing data stored in a shared memory and buffering alterations to the data as speculative alterations to the shared memory. The computing device detects a transaction abort scenario corresponding to the transaction and notifies the application regarding the transaction abort scenario. The computing device determines whether to abort the transaction based on instructions received from the application regarding the transaction abort scenario. When the transaction is to be aborted, the computing device restores the transaction to an operation prior to accessing the data stored in the shared memory and buffering alterations to the data as speculative alterations to the shared memory. When the transaction is not to be aborted, the computing device enables the transaction to continue.
