Abstract
A system and method for providing very large read-sets for hardware transactional memory with limited hardware support by monitoring meta data such as page table entries. The system and method include a Hardware-based Transactional Memory (HTM) mechanism that tracks meta-data such as page-table entries (PTE) rather than all the data itself. The HTM mechanism protects large regions of memory by providing conflict detection so that regions of memory can be located within a local read or write set.
