.... system of second kind Boundary Integral Equations [4] which has been integrated into the framework of the boundary element eld simulation code POLOPT [1] For this code, it is important to deploy a network with both high bandwidth and low latency like the Scalable Coherent Interface (SCI) [6] achieving signi cantly improved performance over standard Ethernet. With such a cluster installed at ABB Corporate Research, Heidelberg, it is now possible to perform realistic eddy current calculations in a shorter amount of time. 2 Physical Background and Simulation Process Eddy currents are ....

....Cluster Computing In the last few years, clusters built from commodity of the shelf (COTS) components have become increasingly popular and have found their way from pure research use to industrial production environments. Existing specialized cluster interconnects, such as Myrinet[3] and SCI [6] provide a considerably higher bandwidth and much lower latencies. All of them are based on the principle of user level communication, enabling applications to directly bene t from the improved communication performance leading to a signi cantly improved overall performance comparable to ....

Besides these, the monitor simulator can stop and restart the monitoring during the simulated execution of programs. This enables the acquisition of per SCI (Scalable Coherent Interface) an IEEE standardized [8] interconnection technology with high bandwidth, low latency, and global physical access space [4] phase information which can be used to optimize applications with dynamic changing access patterns. 6 Validation SIMT is a tool for evaluating shared memory systems.

....of drivers by means of domain specific languages, and the synthesis of the driver kernel in the sense of adaptor synthesis. 3.2. 1 Portable Driver Design In the master thesis of Stein Jrgen Ryan [93] a portable device driver for a shared memory adaptor for a Scalable Coherent Interface (SCI) [100] is described. The driver kernel is wrapped by a kernel interface adaptor, a device hardware abstraction layer and a kernel services adaption layer. The driver kernel invokes different functions which have to be reprogrammed or adapted for a port to a particular operating system. Furthermore, the ....

....to the individual nodes will act as devices in a storage area network (SAN) where the hosting nodes will perform part of the control processing for the local storage devices. This approach can be realized with low processing cost for the nodes, as the interconnect technologies for clusters [6, 16, 17] are changing towards an architecture where the processors (and to a certain extent the memory bus) have little part in the forwarding of data between network and storage devices. Using current technology it is therefore possible to make nodes in a cluster double as configurable, high performance ....

....is a transport independent API for remote data access that can be implemented on any interconnect that supports remote shared memory. Transport specific details are confined to a transport specific plug in library. We have written plug in libraries for the Sun Fire Link interconnect and for SCI [9]. RSMAPI provides functions to retrieve topology information, to export and import memory segments, to put and get remote data, and to perform memory barrier operations. Data can be written to or read from an imported memory segment using either the put and get functional interfaces, or ....

....the communication behaviour of his application, taking advantage of the low latency and high bandwidth rates provided by the communication networks. Besides, several implementations of the MPI standard [19] on top of these communication protocols have been done. SCI Scalable Coherent Interface [18] differs from the other communication technologies applied to cluster computing due to its shared memory facilities. This feature stimulates a high level communication abstraction, based on shared segments and remote load store operations; at the same time, it imposes some constraints on the ....

....a global address space. Section 5 presents related work. In Section 6 we conclude with an outlook on future work. 2 SCI Hardware and Raw Performance Data SCI grew out of the desire to develop a scalable bus architecture which could support a large number of processors. SCI is an IEEE standard [IEE93] which describes a scalable coherent interface that allows a large number of nodes to be connected by point to point links, arranged in rings or attached to switches. While the full version of SCI also describes cache coherence and provides true shared memory support, we consider only a limited ....

Later destination stripping with spatial reuse was exploited in systems like MetaRing[6] DQDB [11] ATMR [13] CRMA II [15] and SCI [12].

In which way are these single words encapsulated inside SCI packets As described by the SCI standard [17], a chunk of consecutive data up to an amount of 16 bytes within a 16 byte aligned block can be trans5 ferred by using writesb transactions.

....pressure on RAC mHop is also studied with the results shown in Figure 12. We can see that when the memory pressure is high, the performance drop in RACmHop is relatively smooth compared with that in Figure 10. 7 Related Works The GLOW protocol extension proposed in [23] extends the SCI protocol [20] to a large scale system. The scheme attaches GLOW engines to specific nodes, with these engines bridging two or more SCI rings to form a hierarchy of rings. The GLOW engine acts as a memory directory towards its children and as an ordinary SCI cache towards its parent. The GLOW engine needs a ....
