Grid Based Analysis Toolkit for Partial Wave Analysis

Abstract

To get the physics out of the data, GlueX relies entirely on an amplitude-based analysisâ€"PWA(Partial Wave Analysis). We build a grid test platform to verify how computational and data grid can be used to process large scale dataset in PWA, and make PWA toolkit to be grid-enable. The work we did has demonstrated that grid is a promising computing architecture for PWA in GlueX project. We setup grid computational platform, which consists of three clusters. We also setup data grid platform using dCache and evaluate the file access performance of dCache. A new Condor wrapper for Open MPI is presented in this grid platform. Through revising ruby-PWA package, we parallel ruby-PWA in grid environment. We run some scaling test benchmarks, and the results show grid-enabled ruby-PWA gets high performance in multi-node amplitude analysis.
