This paper focuses on the Cyclops64 computer architecture and presents an analytical model and performance simulation results for the preloading and loop unrolling approaches to optimize the performance of SVD (Singular Value Decomposition) benchmark. A performance model for dissecting the total execution cycles is presented. The data preloading using “memcpy” or hand optimized “inline” assembl...

Legged robots relying on dry adhesives for vertical climbing are required to preload their feet against the wall to increase contact surface area and consequently maximize adhesion force. Preloading a foot causes a redistribution of forces in the entire robot, including contact forces between the other feet and the wall. An inappropriate redistribution of these forces can cause irreparable deta...

Cache prefetching with the assistance of an optimizing compiler is an eeective means of reducing the penalty of long memory access time beyond the primary cache. However, cache prefetching can cause cache pollution and its beneet can be unpredictable. A new architectural support for preloading, the preload buuer, is proposed in this paper. Unlike previously proposed methods of non-binding cache...

In vitro kinetic studies revealed that Taenia crassiceps larvae absorb purine bases (adenine and hypoxanthine) and nucleosides (adenosine and uridine) by mediated transport. Pyrimidines (thymine, uracil, and cytosine) are absorbed primarily by diffusion. The presence of hypoxanthine stimulated adenosine uptake, an effect which was enhanced by preloading the worms with hypoxanthine. Furthermore,...

New analytical and the speedup models for evaluating the performance of a generic reconfigurable coprocessor (RC) system are presented. We present a generic performance model for the speedup of a generic RC system. We demonstrate how different parameters of speedup model can affect the performance of reconfigurable system (RS). In addition, we implement our pre-developed speedup model for a sys...

This article is devoted to developing a mathematical model of nonlinear bearing supports for turbopump units liquid rocket engines considering initial gaps and axial preloading. In addition the radial stiffness support, this also considers cage, rotational speed rotor, preloading rotor (due which inner cage shifts relative outer, changing support), as well between contact elements bearings. mak...

This research work presents the high-speed railway line (HSRL) case study constructed on soft soils deposits. The performance of improvement method combining both PVD’s (Prefabricated vertical drains) and surcharge preloading was evaluated herein based numerical simulation approach to predict induced deformations during HSRL construction phase. For this aim, PVD-assisted in situ measurement dat...
