The Time-Surfer, a 16-processor PC cluster, was built and tested as part of this effort. The total cost was about twenty thousand 1999-dollars. The efficiency and accuracy of the CE/SE method on the Beowulf cluster are assessed to determine feasibility of applying the CE/SE method to CFD calculations of using five million mesh nodes and above on this low-cost platform. The numerical solutions of threedimensional detonations propagating in a square tube are calculated. The diagonal instability pattern of three-dimensional detonations is reported.

Unsteady Separated Flow Simulations Using a Cluster of Workstations
The possibility of predicting the full three-dimensional unsteady separated flow around complex ship and helicopter geometries is explored using unstructured grids with a parallel flow solver. The flow solver used is a modified version of the Parallel Unstructured Maritime Aerodynamics (PUMA) software, which was written by Dr. Christopher Bruner as part of his doctoral thesis at the Virginia Po...
متن کاملScalable parallel FFT for spectral simulations on a Beowulf cluster
The implementation and performance of the multidimensional Fast Fourier Transform on a distributed memory Beowulf cluster is examined. We focus on the the three dimensional (3D) real transform, an essential computational component of Galerkin and pseudo-spectral codes. The approach studied is a one-dimensional domain decomposition algorithm that relies on communication-intensive transpose opera...

We present a novel, highly efficient algorithm to parallelize O(N)direct summation method for N -body problems with individual timesteps on distributed-memory parallel machines such as Beowulf clusters. Previously known algorithms, in which all processors have complete copies of the N -body system, has the serious problem that the communication-computation ratio increases as we increase the num...

متن کاملDirect Calculations of Cavitating Flows by the Space-Time CE/SE Method
This paper reports oneand two-dimensional simulations of cavitating flows by the Space-Time Conservation Element and Solution Element (CE/SE) method. A continuum cavitation model based on specifying the speed of sound of two-phase flows is employed. The CE/SE method is a viable CFD method for flows at wide range of Mach numbers. The method is explicit and is suitable for time accurate simulatio...
