Both the Scalable Coherent Interface (SCI) [7] and the Virtual Interface Architecture (VIA) [8] aim at providing effective cluster communication systems. In previous publications we showed that SCI and VIA can be efficiently combined to form a new communication architecture (e.g. [1, 2]). In this paper we show that despite of having adopted an flexible relatively slow FPGA–based design an appro...

In this paper, the influence of the extra solid phase reaction on the interface structure and mechanical properties of titanium carbonitride-based cermets were investigated. The extra solid phase reaction in the preparation process of cermets could induce the formation of a core/rim/binder interface with the coherent structure and reinforce the interface bonding strength in cermets. The existen...

Local density functional theory ~LDFT! calculations, within the plane-wave-pseudopotential framework, are performed for the $222%MgO/Cu polar interface, with the objective of elucidating the atomic and electronic structure of the interface, as well as interface interatomic potentials. Calculations are performed for both coherent interfaces and semicoherent interfaces that approximate the lattic...

The economic incentive is now so compelling that users are beginning to make the transition to parallel processing, perhaps with only the expectation that they will learn how to adapt their programs to these new machines over time. Both software and hardware technology have made advances that tend to encourage these expectations. Several directions have been explored: Symmetric MultiProcessors ...

IEEE P1596, the Scalable Coherent Interface (formerly known as SuperBus) is based on experience gained while developing Fastbus (ANSI/IEEE 960-1986, IEC 935), Futurebus (IEEE P896.x) and other modern high-performance buses. SC1 goals include a minimum bandwidth of 1 GByte/sec per processor in multiprocessor systems with thousands of processors; efficient support of a coherent distributed-cache ...

The universal thermodynamic driving force for coherent plane interface reorientation (IR) during first-order phase transformations (PT) in solids is derived. The relation between the rates of IR and interface propagation (IP) and the corresponding driving forces are derived for combined athermal and drag interface friction. The coupled evolution of IR and IP during cubic-tetragonal and tetragon...

The research project RD24 [11] is studying applications of the Scalable Coherent Interface (IEEE-1596) standard for the large hadron collider (LHC). First SCI node chips from Dolphin were used to demonstrate the use and functioning of SCI’s packet protocols and to measure data rates. We present results from a first, two-node SCI ringlet at CERN, based on a R3000 RISC processor node and DMA node...

We study the coherent and semi-coherent Al/α-Al2O3 interfaces using molecular dynamics simulations with a mixed, metallic-ionic atomistic model. For the coherent interfaces, both Al-terminated and O-terminated nonstoichiometric interfaces have been studied and their relative stability has been established. To understand the misfit accommodation at the semi-coherent interface, a 1-dimensional (1...
