INDUCING TRANSACTIONAL ABORTS IN OTHER PROCESSING THREADS

摘要

In a transactional memory environment, a computer-implemented method includes a first processor initiating a first transaction and encountering an abort condition. Responsive to the abort condition, an abort other request is communicated between the first processor and one or more additional processors. The one or more additional processors receive the abort other request, and, responsive to the abort other request, the one or more additional processors selectively abort a current second transaction based on the abort other request and an abort other condition. Optionally, the transactional memory environment supports a transaction category scheme, whereby each transaction has associated therewith a category identifier. In such embodiments, the abort other request includes an abort category identifier, and the abort other condition includes aborting the current second transaction if the abort category identifier matches the category identifier for the current second transaction. A corresponding computer program product and computer system are also disclosed.

主权项

1. A computer-implemented method, comprising, in a transactional memory environment having a plurality of processors comprising a first processor and one or more additional processors, and said transactional memory environment supporting one or more transactions by said plurality of processors:
initiating, by said first processor, a first transaction; encountering, by said first processor, an abort condition; responsive to said abort condition, aborting, by said first processor, said first transaction; responsive to said abort condition, communicating an abort other request between said first processor and said one or more additional processors; receiving, by said one or more additional processors, said abort other request; and responsive to said abort other request, selectively aborting, by said one or more additional processors, a current second transaction, based on said abort other request and an abort other condition.
