Use of Cluster OpenMP with the Gaussian Quantum Chemistry Code: A Preliminary Performance Analysis

Yang, Rui; Cai, Jie; Rendell, Alistair; Ganesh (Venkateshwara), V (Ganesh)


The Intel Cluster OpenMP (CLOMP) compiler and associated runtime environment offer the potential to run OpenMP applications over a few nodes of a cluster. This paper reports on our efforts to use CLOMP with the Gaussian quantum chemistry code. Sample results on a four node quad core Intel cluster show reasonable speedups. In some cases it is found preferable to use multiple nodes compared to using multiple cores within a single node. The performances of the different benchmarks are analyzed in...[Show more]
