With the ever-increasing need to solve larger and more complex problems, multiprocessing is attracting more and more research efforts. One of the challenges facing the multiprocessor designers is to fulfill in an effective manner the communications among the processes running in parallel on multiple multiprocessors. The conventional electrical backplane bus provides narrow bandwidth as restrict...

Exokernel is a minimal operating system kernel that safely multiplexes hardware resources, while leaving all system abstractions to applications. An exokernel exhibits better performance and offers more functionality because applications can provide optimized system abstractions, at the user-level, based on their needs. Current design of the exokernel system, however, does not support multiproc...

Multiprocessing systems consisting of many processors, memory modules and interconnection links are being designed and implemented. Improvements in technology have reduced the failure rates of all system components. However, the large increase in the number of components per system has more than offset the increase in reliability of a single component. Therefore, some of the hundreds (or even t...

Typical telecom applications apply a planar architecture pattern based on the processing requirements of each subsystem. In a symmetric multiprocessing environment all applications share the same hardware resources. However, currently embedded hardware platforms are being designed with asymmetric multiprocessor architectures to improve separation and increase performance of noninterfering tasks...

Abstract Monte Carlo N-Particle (MCNP) is a widely-used code in nuclear engineering, but it needs high computation times due to the tracking of every single particle and interaction event. This causes shielding optimization using trial-and-error take long complete. It can be solved by multiprocessing, this requires MCNP source which difficult obtain. Therefore, paper aims suggest solution on ho...

The use of transputer family microprocessors in hard real-time control applications is studied. The transputer offers computing performance and architectural features like support of process scheduling and multiprocessing on hardware and language level. Some of these features are efficient for real-time systems, but some contradict with the system performance. Occam process structure is matched...

The hardware evolution has reached the point where it becomes extremely difficult to further improve the performance of superscalar processors by either exploiting more instruction-level parallelism (ILP) or using new semiconductor technologies. The effort to increase processor performance by exploiting ILP follows the law of diminishing returns: new, more complex optimisations tend to cost mor...

We study a multiprocessing computer system which accepts parallel programs that have a fork-join computational paradigm. The multiprocessing computer system under study is modeled as K homogeneous servers, each with an infinite capacity queue. Parallel programs arrive at the multiprocessing system according to a series-parallel phase type interarrival process with mean arrival rate of l. Upon t...

The recent advent of Multiple Instruction Multiple Data (MIMD) architectures together with the potentially attractive application of range images for object recognition, motivated the development of a successful goal-directed 3-D object recognition system on a 18 node Butterfly multiprocessor. This system, which combines the use of range images, multiprocessing, and rule-based control in a uniq...
