Transactional memory execution utilizing virtual memory

A method comprising:

• determining whether a local transactional cache is capable of accommodating a transactional memory transaction request from a requesting thread;
• performing the transactional memory transaction with the local transactional cache if the local transactional cache is capable of accommodating the transactional memory transaction;
• and
• overflowing data for the transactional memory transaction request into an application virtual address space associated with the requesting thread if the local transactional cache is not capable of accommodating the transactional memory transaction request.

A machine-readable medium having stored thereon instructions, which when executed by a machine, cause the machine to perform the following operations comprising:

• determining whether a local transactional cache is capable of accommodating a transactional memory transaction request from a requesting thread;
• performing the transactional memory transaction with the local transactional cache if the local transactional cache is capable of accommodating the transactional memory transaction;
• and
• overflowing data for the transactional memory transaction request into an application virtual address space associated with the requesting thread if the local transactional cache is not capable of accommodating the transactional memory transaction request.

A computer system comprising:

• a processor including a local transactional cache;
• a database;
• and
• a resource manager, the resource manager responsive to a transactional memory transaction request from a requesting thread from an application program interface (API) requesting to access memory in a database, the resource manager to determine whether the local transactional cache is capable of accommodating the transactional memory transaction request and, if so, the local transactional caches performs the transactional memory transaction;
• wherein, if the local transactional cache is not capable of accommodating the transactional memory transaction request, data for the transactional memory transaction request is overflowed into an application virtual address space associated with the requesting thread.
