摘要:

Numerical astrophysics is filled with a wide range of computational challenges. Many of these relate to developing a code for solving a given problem, or preferably a code that can address a large class of problems. Once the code is built, it is necessary to test it to make sure that the results are believable. Direct validation of astrophysics codes is virtually impossible, so other techniques must be employed. Finally, there are many challenges associated with performing the simulations, in particular managing the huge quantities of data produced and performing analysis and visualization of the results. ©2001 American Institute of Physics.

摘要:

We discuss some of the computational challenges encountered in simulating the evolution of clusters of galaxies. Eulerian adaptive mesh refinement (AMR) techniques can successfully address these challenges but are currently being used by only a few groups. We describe our publicly available AMR code, FLASH, which uses an object-oriented framework to manage its AMR library, physics modules, and automated verification. We outline the development of the FLASH framework to include collisionless particles, permitting it to be used for cluster simulation. ©2001 American Institute of Physics.

摘要:

In this article we will discuss the current status of the CMS software. A first major Monte Carlo production was conducted in Spring 2000. We will discuss the experiences we collected during this production. A Distributed Monte Carlo production is currently in progress (Fall 2000). ©2001 American Institute of Physics.

摘要:

The Sloan Digital Sky Survey is among the first of the new generation of large scale sky surveys that enabling the construction of revolutionary new cluster catalogs. I describe here some of the experiences of creating a SDSS cluster catalog, some of the computational challenges we encountered, and what we can expect in the near future. ©2001 American Institute of Physics.

摘要:

The muon collider and the neutrino source are very challenging projects. Recently, a feasibility study for a 20 GeV muon storage ring yielding on the order of1019muon decays per year has been successfully completed by the muon collider/neutrino source collaboration. Simulation tools are crucial to support these conceptual design efforts. In this paper, we will present different software packages used in simulations related to the neutrino factory study. ©2001 American Institute of Physics.

摘要:

From the earliest stages, simulation has played a key role in designing the ATLAS detector for LHC. For more than ten years the detector simulation was done using the FORTRAN-based GEANT3 program. Work is now underway to move the simulation to the object-oriented GEANT4 program. ©2001 American Institute of Physics.
