This paper describes a new approach to register-pressure-aware instruction scheduling, using Ant Colony Optimization (ACO) . ACO is nature-inspired optimization technique that researchers have successfully applied NP-hard sequencing problems like the Traveling Salesman Problem (TSP) and its derivatives. In this work, we describe an algorithm for solving long-standing compiler problem of balanci...

The register allocation in loops is generally carried out after or during the software pipelining process. This is because doing the register allocation at first step without assuming a schedule lacks the information of interferences between values live ranges. The register allocator introduces extra false dependencies which reduces dramatically the original ILP (Instruction Level Parallelism)....

Introduction: The aim of present study was to investigate the effects of royal jelly (RJ) on the number of Nissl-stained neurons in caudate putamen unit (CPU) and substantia nigra pars compacta (SNC) and the thickness of gray (TGm) and white matter (TWm) of cerebral and cerebellar cortex in male rats with Parkinson’s disease (PD). Methods: Seventy five Sprague-Dawley adults’ male ra...

Due to shrinking transistor sizes and lower supply voltages, transient faults (soft errors) in computer systems are projected to increase by orders of magnitude. Fault detection and recovery can be achieved through redundancy. Redundant multithreading (RMT) is one attractive approach to detect and recover from these errors. However, redundant threads can impose significant performance overheads...

The range migration algorithm (RMA) based on Fourier transformation is widely applied in millimeter-wave (MMW) close-range imaging because of its few operations and small approximation. However, interpolation stage not effective due to the involved intensive logic controls, which limits speed performance a graphics processing unit (GPU) platform. Therefore, this paper, we present an acceleratio...

Advanced Persistent Threat (APT) attackers apply multiple sophisticated methods to continuously and stealthily steal information from the targeted cloud storage systems and can even induce the storage system to apply a specific defense strategy and attack it accordingly. In this paper, the interactions between an APT attacker and a defender allocating their Central Processing Units (CPUs) over ...

The Internet of Things significantly increases the amount of data generated, straining the processing capability of current computing systems. Approximate computing is a promising solution to accelerate computation by trading off energy and accuracy. In this paper, we propose a resistive content addressable memory (CAM) accelerator, called RCA, which exploits data locality to have an approximat...

a method based on the genetic algorithm (ga) was developed to study the phase behavior of multicomponent and multiphase systems. upon application of the ga to the thermodynamic models which are commonly used to study the vle, vlle and lle phase equilibria, the physically meaningful values for the binary interaction parameters (bip) of the models were obtained. using the method proposed in this ...
