#CACTUS FLESH NMS HOW TO#
take advantage of research groups that spend their time thinking about the fastest way to bring simulation data to disk or how to visualize it while the code is running.
#CACTUS FLESH NMS SOFTWARE#
make use of the latest software technology: e.g. work with collaborators on the same code and avoid having your programs fragmented.
#CACTUS FLESH NMS PC#
10Īnd simply move your code to a supercomputer (like a Cray T3E or Origin) to go into production right away! engage in high performance cluster computing or get first parallel experience by turning your networked PC pool into a computing cluster. develop your code on the most convenient machine available, for example your workstation or laptop. Run on a wide range of architectures and operating systems. Perform parallel programming in an easy but powerful manner using the language of your choice: F77, F90, C, C++. You should consider using Cactus if you need to perform any of the following tasks - now or in future: If your only goal is to implement a simulation of a 1D wave equation, you probably don't want to use Cactus.

Powerful Application Programming Interface. Supported on most architectures Sophisticated make system PETSc is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. HDF5 is a library and file format for storing scientific data. The Globus Project is developing fundamental technologies needed to build computational grids. Cactus provides easy access to many cutting edge software technologies being developed in the academic research community, including the Globus Metacomputing Toolkit, HDF5 parallel file I/O, the PETSc scientific library, adaptive mesh refinement, web interfaces, and advanced visualization tools. Other thorns from a standard computational toolkit provide a range of computational capabilities, such as parallel I/O, data distribution, or checkpointing.Īpplications, developed on standard workstations or laptops, can be seamlessly run on clusters or supercomputers. Thorns can implement custom developed scientific or engineering applications, such as computational fluid dynamics. The name Cactus comes from the design of a central core (or "flesh") which connects to application modules (or "thorns") through an extensible interface. Its modular structure easily enables parallel computation across different architectures and collaborative code development between different groups.Ĭactus originated in the academic research community, where it was developed and used over many years by a large international collaboration of physicists and computational scientists. Episode one: What is cactus? Ĭactus is an open source problem solving environment designed for scientists and engineers.
