Abstract:

A terascale computing system was purchased and brought into full operation. The main cluster consisted of 36dual-dual-core Dell servers connected by a QLogic InfiniBand switch. The full system included 2 interactive servers holding 2 terabytes of fi le storage. The cluster enabled combustion simulations to run on up to 140processor cores. On benchmarking tests with HP Linpack, the system was found to perform well, achieving 1.15teraflops, or 68.7 of the theoretical peak based on the clusters 3.0-GHz Intel processors. Initial tests on codes used in turbulent combustion research showed excellent scalability. The system served as an excellent resource for turbulent combustion research and for the training of graduate students in high-performance computing.
