ABSTRACT:
For a variable accessed at least once in a software-based transactional memory system (STM) defined (STM-defined) critical region of a program, modifying an access to the variable that occurs outside any STM-defined critical region system by starting a hardware based transactional memory based transaction, within the hardware based transactional memory based transaction, checking if the variable is currently owned by a STM transaction, checking if the variable is currently owned by a STM transaction; if the variable is not currently owned by a STM transaction, performing the access and then committing the hardware based transactional memory transaction; and if the variable is currently owned by a STM transaction, performing a responsive action.
