A Technical Report On Grid Benchmarking using ATLAS V.O

TL;DR

This paper discusses grid benchmarking using ATLAS V.O to measure heterogeneity in grid resources, highlighting how diverse hardware and software impact performance through simple benchmarking tests.

Contribution

It introduces a benchmarking approach to quantify heterogeneity across grid sites, aiding performance evaluation and resource management.

Findings

Heterogeneity significantly affects grid performance.

Benchmarking reveals performance differences across sites.

Simple tests can effectively measure resource diversity.

Abstract

Grids include heterogeneous resources, which are based on different hardware and software architectures or components. In correspondence with this diversity of the infrastructure, the execution time of any single job, as well as the total grid performance can both be affected substantially, which can be demonstrated by measurements. Running a simple benchmarking suite can show this heterogeneity and give us results about the differences over the grid sites.
