In this supplement, we analyze the system-level bottlenecks of Shotgun’s scalability on multicore. Currently, we are able to get maximum of about 3− 4× speedup on 8 cores. To analyze multicore performance, we run a series of tests which try to isolate effects of various factors. Our analysis indicates that Shotgun is held back by memory access, but we give suggestions for future improvements to...

The core problem of multi-agent distributed data mining technology not concern particular data mining techniques although the latter is now paid the most attention. Its core problem concerns collaborative work of distributed software in design of multi-agent system destined for distributed data mining and classification. The paper presents the developed and implemented distributed data mining t...

Nowadays, multi-core processors are becoming main stream in computer market due to their high performance, low cost and less power consumption characteristics. However, multi-core processors give rise to new problems when they are applied to real-time system. Little attention has been focused on tasks' DMR(deadline miss rate) by using previous multi-core real time scheduling algorithms under th...

A paradigm shift from single-core to parallel multi-core processors has occurred over the last couple of years to further increase the performance of processors. Originating in high-performance computing, this trend has quickly reached general purpose and finally also embedded central processing units (CPUs). Continuing advances in chip manufacture will not only allow an increasing number of ho...

A new nozzle system for the efficient production of multi-layered nanofibers through electrospinning is reported. Developed a decade ago, the commonly used coaxial nozzle system consisting of two concentric cylindrical needles has remained unchanged, despite recent advances in multi-layered, multi-functional nanofibers. Here, we demonstrate a core-cut nozzle system, in which the exit pipe of th...

despite the extensive deployment of multi-core architectures in the past few years, the design and optimization of each single processing core is still a fresh field in computing .on the other hand, having a design procedure (used to solve the problems related to the design of a single processing core )makes it possible to apply the proposed solutions to specific-purpose processing cores .the i...
