چکیده
|
In this paper, we propose a new concurrency control algorithm based on multi-agentsystems which is an extension of majority protocol. then, we suggest a clustering approach to getbetter results in reliability, decreasing message passing and algorithm’s runtime. here, we consider ndifferent transactions working on non-conflict data items. considering execution efficiency of somedifferent transactions simultaneously is one of our algorithm features. for evaluating performance ofthe proposed algorithm we applied it using the mpich2 mechanism.
