We present results of 3D numerical simulations using a finite difference code featuring fixed
mesh refinement (FMR), in which a subset of the computational domain is refined in space …

We describe Cactus, a framework for building a variety of computing applications in science
and engineering, including astrophysics, relativity and chemical engineering. We first …

While distributed, heterogeneous collections of computers (" Grids") can in principle be used
as a computing platform, in practice the problems of first discovering and then organizing …

The ability to harness heterogeneous, dynamically available grid resources is attractive to
typically resource-starved computational scientists and engineers, as in principle it can …

In heterogeneous and dynamic environments, efficient execution of parallel computations
can require map**s of tasks to processors whose performance is both irregular (because …

We present a suite of Mathematica-based computer-algebra packages, termed “Kranc”,
which comprise a toolbox to convert certain (tensorial) systems of partial differential …

High performance computing (HPC) systems use checkpoint-restart to tolerate failures.
Typically, applications store their states in checkpoints on a parallel file system (PFS). As …

If we were to have a Grid infrastructure for visualization, what technologies would be needed
to build such an infrastructure, what kind of applications would benefit from it, and what …

Grid Portals, based on standard Web technologies, are emerging as important and useful
user interfaces to computational and data grids. Grid portals enable virtual organizations …

The monkeypox virus (MPXV) is an enveloped, double-stranded DNA virus belonging to the
genus Orthopox viruses. In recent years, the virus has spread to countries where it was …
