The effects of multiprogramming on barrier synchronization
Proceedings of the Third IEEE Symposium on Parallel and Distributed Processing, 2002One of the most common ways to share a multiprocessor among several applications is to give each application a set of dedicated processors. To ensure fairness, an application may receive fewer processors than it has processes. Unless an application can easily adjust the number of processes it employs during execution, several processes from the same ...

Reflex Barrier: A Scalable Network-Based Synchronization Barrier
2011 IEEE 17th International Conference on Parallel and Distributed Systems, 2011High-performance computing is witnessing the proliferation of multi-core processors in parallel architectures, and the trend is expected to increase further with the emerging many-core technology, leading to hundreds of processing cores within each compute node in the near future.

A reliable hardware barrier synchronization scheme
Proceedings 11th International Parallel Processing Symposium, 2002Barrier synchronization is a crucial operation for parallel systems. Many schemes have been proposed in the literature to achieve fast barrier synchronization through software, hardware, or a combination of these mechanisms. However few of these schemes emphasize fault-tolerant barrier operations. In this paper, we describe inexpensive support that can

Compile time barrier synchronization minimization
IEEE Transactions on Parallel and Distributed Systems, 2002This paper presents a new compiler approach to minimizing the number of barriers executed in parallelized programs. A simple procedure is developed to reduce the complexity of barrier placement by eliminating certain data dependences, without affecting optimality.

Bulk synchronous parallel without barriers
Proceedings. 24th EUROMICRO Conference (Cat. No.98EX204), 2002BSP oriented runtime systems try to get closer actual machines to the BSP ideal machine by packing individual messages generated during a superstep and optimizing communication time by rearranging the order in which messages are sent at the end of the superstep.

ALLNODE barrier synchronization network
Proceedings of 9th International Parallel Processing Symposium, 2002This paper presents a proposed hardware solution using an existing multi-stage switching network for synchronizing N multiple processors at predetermined programmable barriers. The technique permits all N processors to access the network simultaneously and to perform synchronization in parallel using only several network cycles.

A network model of barrier synchronization algorithms
International Journal of Parallel Programming, 1991We consider two algorithms for the barrier synchronization of \(N\) processes: the dissemination algorithm and Brooks algorithm in \textit{E. D. Brooks} [Int. J. Parallel Program. 15, 295-307 (1986; Zbl 0641.68010)] and \textit{D. Heusgen}, \textit{R. Finkel} and \textit{U. Mauber} [Int.J. Parallel Program. 17(1), 1-17 (1988; Zbl 0662.68008)].

Barrier synchronization techniques for distributed process creation
Proceedings of 8th International Parallel Processing Symposium, 2002Synchronization techniques are proposed for algorithms which spawn processes remotely on loosely coupled processors based on run-time characteristics. The performance of the proposed synchronization schemes are measured on the iPSC/2 and SNAP-1 multiprocessors and their implementation cost is discussed.

Effects of synchronization barriers on multiprocessor performance
Parallel Computing, 1986Abstract Synchronization barriers are frequently required by numerical algorithms for multiprocessors. When the number of processors becomes large these barriers may cause significant performance degradation. This paper examines the performance of two alternative types of synchronization barriers using simulation tools.
