See full text

Prevention of a prefetch memory operation from causing a transaction to abort. A local processor receives a prefetch request from a remote processor. A processor determines whether the prefetch request conflicts with a transaction of the local processor. A processor responds to at least one of i) a determination that the local processor has no transaction, and ii) a determination that the prefetch request does not conflict with a transaction by providing a requested prefetch data by providing a requested prefetch data. A processor responds to a determination that the prefetch request conflicts with a transaction by suppressing a processing of the prefetch request.
