Sun Fire fast on FluentMountiew 25 September 2001 The new Sun Fire 15K excels on FLUENT, an important Computational Fluid Dynamics (CFD) software application.
The FL5L1 benchmark models the flow around a fighter aircraft at transonic speeds. In this test, the Sun Fire 15K server demonstrated a 59x speedup on 72 CPUs, which shows near-linear scalability. Sun continues to expand on its ability to produce systems which
effectively use all of the CPUs available.
The FLUENT application is used to analyze the flow of gases and liquids around complex structures that occur in the automotive, aerospace, and other industrial engineering applications. Additional capabilities of the Fluent application allow for the simulation of
heat-transfer applications.
The Fluent 5 benchmark was performed on a 72-way Sun Fire 15K server with 288 GB of memory, running the Solaris 8 Operating Environment and Sun HPC ClusterTools 4 software. In addition, the code used in the benchmark was compiled for the previous generation UltraSPARC II system to prove that there are no compatibility issues when
applications move to the UltraSPARC III platform.
The Fluent 5 benchmark also contains 7 other test cases. All of these
results can be found at http://www.fluent.com/.
Results proved the effectiveness of huge memory and scalability of the Sun Fire 15K
system. The Sun Fire 15K server supports up to 106 UltraSPARC III CPUs with over half a terabyte of memory and is designed to meet the most demanding real-world scientific computing applications.
