We would like to thank the CASTLE/Split-C group at UC Berkeley, especially the help and encouragement from David Culler, Arvind Krishnamurthy, and Lok Tin Liu. Computational support on UC Berkeley's 64-processor TMC CM-5 was provided by NSF Infrastructure Grant number CDA-8722788. We also thank Toby Harness and the Numerical Aerodynamic Simulation Systems Division of NASA's Ames Research Center for use of their 160-node IBM SP-2-WN.
Also, Klaus Schauser, Oscar Ibarra, and David Probert of the University of California, Santa Barbara, provided access to the UCSB 64-node Meiko CS-2. The Meiko CS-2 Computing Facility was acquired through NSF CISE Infrastructure Grant number CDA-9218202, with support from the College of Engineering and the UCSB Office of Research, for research in parallel computing.
Arvind Krishnamurthy provided additional help with his port of Split-C to the Cray Research T3D [2]. The Jet Propulsion Lab/Caltech 256-node Cray T3D Supercomputer used in this investigation was provided by funding from the NASA Offices of Mission to Planet Earth, Aeronautics, and Space Science. Use of the University of Alaska - Arctic Region Supercomputing Center's 128-node Cray T3D was supported by a grant from the Strategic Environmental Research and Development Program under the sponsorship of the U.S. Army Corps of Engineers, Waterways Experiment Station. The content of this paper does not necessarily reflect the position or the policy of the government and no official endorsement should be inferred.
We also acknowledge William Carlson and Jesse Draper from the Center for Computing Science (formerly Supercomputing Research Center) for writing the parallel compiler AC (version 2.6) [12] on which the T3D port of Split-C has been based.
We would like to acknowledge the use of a 16-node IBM SP-2-TN2, which was provided by an IBM Shared University award and an NSF Research Infrastructure Initiative Grant No. CDA9401151.
The discussions with David Helman and Simon Hawkin proved helpful, and we greatly appreciate their suggestions which improved this research.
