....equipment used was donated by Intel and Microsoft. 1. Introduction With the widespread use of increasingly powerful commercial o# the shelf (COTS) products, some system designers have started a shift from custom development to COTS based systems to achieve lower costs and more flexible systems [GiK99, HaZ95]. However, to use COTS based systems e#ectively as parts of a larger system, one needs to exploit the heterogeneity in processor speeds, memory structures, specialized hardware capabilities, etc. that most likely will be present in di#erent COTS products. Heterogeneous computing (HC) is the ....

....systems: These systems include avionics mission computing systems, tactical command and control systems, and manufacturing process control systems. This type of real time applications require the support for various types of QoS aspects such as bandwidth, latency, jitter, and time dependability [4]. Recent large scale mission critical applications require the interaction among large numbers of distributed tasks that are running on several distributed computing nodes. For instance, in avionics mission computing systems, the aircraft controller must collaborate with remote command and control ....

Distributed electronic medical imaging systems (EMIS) Advances in the areas of high speed networking and hierarchical storage management facilitate the building of large scale, distributed, performancesensitive EMISs. Distributed EMISs require a great deal of exibility, performance and QoS ....

.... task to a multiplicity of cheap commodity computation hardware devices [6] The strong requirements on the system s communication efficiency and the need to incorporate a variety of hardware and software modules make the selection of current off the shelf software infrastructures difficult [7]. Some CORBA implementations [8, 9, 10] JINI [11] or Globus [12] provide enough modularity, but they do not satisfy the efficiency requirements. Tools that provide low level APIs to access the network such as PVM [13] MPI [14] Active Messages [15] or Nexus [16] merely exhibit the required ....

....in the efficiency of communication middleware. Middleware resides between applications and the underlying operating systems, protocol stacks, and hardware. It aims at reducing the effort required to develop high quality systems by composing applications out of reusable software component services [33]. Building long living systems without the support of middleware is not imaginable anymore. They decouple the application from the diverse low level services. Although link speeds are increasing fast and processor cycle times dwindle, the time to actually handle an incoming message in software ....

These systems impose timing constraints on both critical and non critical operations, across distributed endsystems and networks. Likewise, these systems often require embedded processor and network resources, so that both time and space utilization are constrained. Many of these systems also ....
