A Numerical Modeling MATLAB Approach to Memory Behavior on a Multi-core Architecture on a Beowulf Cluster Single-Node
نویسنده
چکیده
This paper studies a numerical modeling approach to memory behavior by using bandwidth performance of a single compute-node on a Scyld Beowulf cluster. The CacheBench benchmark is used to obtain memory bandwidth values as it is implemented in simulated single and multiprocess execution on the Scyld cluster. The polynomial curvefitting linear regression is the modeling approach to represent the memory behavior using MATLAB polyfit() function. The models show bandwidth performance for each process for single-instance and distinct bandwidth models for multiinstance and special cases of CacheBench. Model accuracy at large problem sizes in all scenarios depict actual values from CacheBench programs; however, improvement on modeling approach in using polyfit() function is necessary to better represent lower problem sizes for all scenarios.

Load Balancing Approach Based on Limitations and Bottlenecks of Multi-core Architectures on a Beowulf Cluster Compute-Node
This paper studies the improvement of performance and execution time of a single compute-node in a Beowulf cluster. We want to implement a load balancing approach through the Linux scheduler which improves the performance and execution time of High Performance Linpack (HPL) benchmark. We compare the performance and execution time when spawning processes for two processing cores in a local proce...
متن کاملParallel Solution-adaptive Scheme for Multi-phase Core Flows in Rocket Motors
The development of a parallel adaptive mesh refinement (AMR) scheme is described for solving the governing equations for multi-phase (gas-particle) core flows in solid propellant rocket motors (SRM). An Eulerian formulation is used for both the gas and particle phases, which leads to a degenerate hyperbolic system of partial differential equations. The cause and effect of the degeneracy is exam...
متن کاملThermo-mechanical behavior of shape memory alloy made stent- graft by multi-plane model
Constitutive law for shape-memory alloys subjected to multi-axial loading, which is based on a semi-micromechanical integrated multi-plane model capable of internal mechanism observations, is generally not available in the literature. The presented numerical results show significant variations in the mechanical response along the multi loading axes. These are attributed to changes in the marten...
متن کاملStudy of Free Alternative Numerical Computation Packages
Matlab is the most popular commercial package for numerical computations in mathematics, statistics, the sciences, engineering, and other fields. Octave, FreeMat, and Scilab are free numerical computational packages that have many of the same features as Matlab. They are available to download on the Linux, Windows, and Mac OS X operating systems. We investigate whether these packages are viable...
متن کاملTelescoping Architectures: A Methodology for Evaluating Next-Generation Heterogeneous Computing
Architectural innovation has telescoped the HPC community from the commodity (Beowulf) cluster in a machine room, i.e., a multi-node system with Ethernet interconnect, to a commodity cluster on a chip, i.e., multicore CPU with an ondie interconnect. We project that this “telescoping architecture” will apply more broadly to heterogeneous computing, namely from heterogeneous clusters like Tianhe-...
