....split scheme of X, Y, and Z Lagrangian and remap steps, which are computed as three separate sweeps through the mesh per timestep. Message passing provides updates to ghost cells from neighboring domains three times per timestep. OpenMP provides thread level parallelism within MPI tasks. Sweep3D [8, 13] is a solver for the 3 D, time independent, particle transport equation on an orthogonal mesh and it uses a multidimensional wavefront algorithm for discrete ordinates deterministic particle transport simulation. Sweep3D benefits from multiple wavefronts in multiple dimensions, which are ....

....number of processors. Section 3.2.2 demonstrates that STORM exhibits such good scalability that applications running on large clusters can be coscheduled almost as rapidly as small clusters. The applications we use for our experiments in this section are a synthetic CPU intensive job and SWEEP3D [23], a time independent, Cartesian grid, single group, discrete coordinates , deterministic, particle transport code taken from the Accelerated Strategic Computing Initiative (ASCI) workload. SWEEP3D represents the core of a widely utilized method of solving the Boltzmann transport equation. ....

....control flow information, resource usage information (e.g. number of operations) communication structures and mapping information for a parallel or distributed system. In the work presented in this paper, the use of the PACE system is described through an example application kernel Sweep3D [8]. Sweep3D is a part of the Accelerated Strategic Computing Initiative (ASCI) application suite [9] which has been used to evaluate advanced parallel architectures at Los Alamos National Laboratories. The capabilities for performance evaluation within PACE are illustrated through the ....

....example application Sweep3D. 3 Sweep3D: An Example Application In this section we illustrate the PACE modelling capabilities for performance prediction of Sweep3D a complex benchmark for evaluating wavefront application techniques on high performance parallel and distributed architectures [8]. This benchmark is also being analysed by other performance prediction approaches including POEMS [2] This section contains a brief overview and the model description of this application. In Section 4 the model is validated with results on two high performance systems. 3.1 Overview of Sweep3D ....

.... solution of 3D time independent, neutron particle transport equations [2] Available in FORTRAN code in the public domain, it forms the kernel of an ASCI application and involves solving a group of time independent discreteordinate (Sn) neutron particle transport equations on a XYZ cartesian cube [20]. The XYZ geometry is represented by an IJK logically rectangular grid of cells. The angular dependence is handled by discrete angles with a spherical harmonics treatment for the scattering source. The solution involves two steps: the streaming operator is solved by sweeps for each angle and the ....

....powerful OpenMP tools, they should perform better than the MPI on the Origin2000. The second experiment in OpenMP is to implement a typical parallel application code on the Origin2000 by OpenMP. This application is a deterministic particle transport code with wavefront pipeline structure: SWEEP3D [3]. This code has inherent parallelism through its wavefront pipeline structure with multi wavefronts executed concurrently. The MPI version of this code has been widely ported to variety of parallel platforms. The parallelization of this 3 D wavefront SWEEP3D uses a 2 D processor decomposition of ....
