In what case do you like reading so much? What about the type of the unix systems for modern architectures symmetric multiprocessing and caching for kernel programmers book? The needs to read? Well, everybody has their own reason why should read some books. Mostly, it will relate to their necessity to get knowledge from the book and want to read just to get entertainment. Novels, story book, an...

The complexity of modern computer systems, coupled with the diverse workloads that they must support, presents a challenge to researchers and designers who need to understand a system’s behavior. We describe SimOS, a machine simulation environment designed for the efficient and accurate study of both uniprocessor and multiprocessor computer systems. SimOS simulates computer hardware in enough d...

UNIX provides a programming model for the user which gives an illusion of multiprocessing. On uniprocessors, this illusion works well, providing communication paths, firewalls between processes and a simple programming environment. Unfortunately, the normal UNIX model does not provide the capabilities to take full advantage of modern multiprocessor hardware. This results from a design which use...

BLAST is a tool for finding biologically similar sequences to given query sequences in annotated sequence database. Since the number of sequences in the database increases at exponential rate, and the number of users drastically increases, the performance of BLAST is a primary concern to service sites like NCBI. NCBI developed a parallel BLAST for the speedup of BLAST using threads on SMP machi...

Progettazione concorrente hw/sw di sistemi dedicati multiprocessore valuable experience and the unconstrained help that they have provided to me. Moreover, I would like to thank all the students that I had the opportunity to work with and that have been a valuable support in many occasions. I would especially like to mention Luca Del Vecchio, Azzurra Persico and Aldo Vico. Finally, I would like...

The results presented here are based on many years of experience of development and application of DYANA – an environment for analysis of multiprocessor computer systems operation. The architecture and basic features of such an environments are discussed. Main problems arizing during such an environments design are highlighted and possible solutions are shown. The key features of the DYANA envi...

operations often require complex facilities for their data processing. This application required a multiprocessor configuration controlled by a single job step running continuously for many hours a day. Discussed are the special access methods and recovery procedures designed for this environment. The paper also describes a particularly eficient sorting technique evolved for handling large...

ions for open, interacting, multiprocessor systems. Also the combination of the appropriate modeling, analysis and synthesis techniques into model-driven development trajectories for different types of systems is still open. Standardized model-driven development trajectories accepted by industry are crucial for the development of reliable, high-quality, cost-effective embedded systems. If we do...

It is proposed to apply modern methods of nonlinear nonequilibrium statistical mechanics to develop software algorithms that will optimally respond to tar­ gets within short response times with minimal com­ puter resources. This Statistical Mechanics Algorithm for Response to Targets (SMART) can be developed with a view towards its future implementation into a hardwired Statistical Algorithm Mu...
