The design of an interconnection network and switch architectural design are significantly influenced by contemporary supercomputer technology. As technology evolves, its impact on interconnection network needs to be re-evaluated and elaborated. In this paper we have traced the path in this direction and addressed performance analyses of a high speed 4x4(More)
This paper proposes an intelligent component based approach for batch control based on ANSI/ISA S88 standard. Common intelligent software components have been built and reused for different application. The components are managed in a control recipe that describes their execution schedule. Furthermore, IEC 61499 standard is adopted as an application(More)
As modern scientific and engineering computing matures, the demands for high-speed computational resources are growing at a rapid rate. The communication performance of system area network is a crucial factor influencing the parallel performance of computer clusters which form the prevailing architecture of modern high-performance computer systems. In this(More)
Modeling of batch process control over several hierarchical layers is proposed in ISA S88, independently of a concrete implementation. IEC 61499, describes models to implement distributed control systems. This contribution proposes to combine the concepts of ISA S88 for hierarchical design with the models of IEC 61499 for distributed implementation. To(More)
Резюме Разглежда се спецификата на съзависимото поведение, моделите на терапевтично въздействие, тяхната научна обоснованост и практическа ефективност. Фокусът е върху възможностите на мотивационното интервюиране – една сравнително нова терапия в областта на зависимите поведения със специфични техники, които са насочени към проява и мобилизиране на(More)
Potato spindle tuber viroid (PSTVd) is an infectious small, circular, non-coding single-stranded RNA that induces disease on many crop species, ornamental plants, weeds and parasitic plants. PSTVd propagate in their host as a population of closely related but non-identical RNA variants referred to as quasispecies. Recently, we have described three de novo(More)
The communication performance of multistage interconnection networks is a crucial factor influencing the parallel performance of high-performance computer clusters. In this paper we have proposed a methodology for parallelization of an OMNET++ sequential model. We designed in parallel manner a multistage BBN interconnect network topology to meet the demands(More)
The paper focuses on the latest trends in supercomputer and high-performance computer architectures with emphasis of the important parameters for parallel computer performance. The main objective is to propose the high-speed network architecture for collective communications in supercomputers "Silicon Galaxy" that provides high-bandwidth, low latency and(More)
