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 terms of page faults and by using a critical path analysis technique.
