Title:
PROCESSING NODE, COMPUTER SYSTEM AND TRANSACTION CONFLICT DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/129036
Kind Code:
A1
Abstract:
Disclosed in the present application is a processing node, a computer system and a transaction conflict detection method. The processing node comprises a processing unit and a transaction cache. When the processing unit acquires an instruction to access a transaction of shared data, the processing unit accesses the transaction cache according to the operation instruction. The transaction cache is used to cache the shared data of the transaction that is being processed by the processing node, and the shared data are data that can be accessed by both the processing node and other processing nodes. If the transaction cache determines that the operation instruction does not hit a cache line in the transaction cache, the transaction cache sends a destination address in the operation instruction to transaction caches of the other processing nodes, and receives status information that the cache line has been hit by the destination address, as returned by the transaction caches of the other processing nodes. Thereafter, the transaction cache determines whether the operation instruction is in conflict with an operation instruction currently executed by the other processing nodes according to the status information received thereby.
