The recent switch to parallel microprocessors is a milestone in the history of computing.
Industry has laid out a roadmap for multicore designs that preserves the programming …

Although InfiniBand Architecture is relatively new in the high performance computing area, it
offers many features which help us to improve the performance of communication …

The scale of applications and computing systems is tremendously increasing and needs to
increase even more to realize exascale systems. As the number of nodes keeps growing …

Today's largest High Performance Computing (HPC) systems exceed one Petaflops (10^ 15)
floating point operations per second) and exascale systems are projected within seven …

Performance prediction across platforms is increasingly important as developers can choose

In this paper, we present a comprehensive performance comparison of MPI implementations
over Infini-Band, Myrinet and Quadrics. Our performance evaluation consists of two major …

The performance of a computer system depends on the characteristics of the workload it
must serve: for example, if work is evenly distributed performance will be better than if it …

On-chip interconnects provide a vital facility for highly parallel MultiProcessor Systems-on-
Chip, particularly in data-intensive applications, where the choice of the underlying …

In this paper, we present the Tianhe-2 interconnect network and message passing services.
We describe the architecture of the router and network interface chips, and highlight a set of …

Message Passing Interface (MPI) is a popular parallel programming model for scientific
