Most parallel computations require the exchange of data between processing elements. One of important basic communication operations is all-reduce, a variation of the reduction operation. this paper presents an all-reduce communication operation scheme using all-to-all broadcast communication pattern. All-to-all broadcast is the operation in which each processor sends its message to all other processors, and receives messages from all other processors in the system. In this paper, we develop an efficient all-reduce operation scheme in a star network topology withthe single-port communication capability. Communication time is compared against known broadcasting schemes to verify the efficiency of the suggested scheme.

A new method for controlling concurrent read/write operations upon inverted files is proposed and evaluated. Communication and synchronization among processors is effected by ways of the bulk-synchronous parallel model of computing. thanks to the global synchronization property of this model, a simple but very efficient mechanism for synchronizing read/write operations is feasible at very low overheads in running time. Experimental results using a large text collection show that our method is more efficient than traditional approaches to the synchronization problem.
