Linda and Paradise Now Available for Linux

New Haven, CT, November 9, 1998: Scientific Computing Associates today announced that Linda and Paradise, its parallel and distributed computing development tools, are now available for Linux, a free version of UNIX designed to run on Intel-based PCs and Internet servers. The products also support Beowulf clusters, networks of PCs that can be used as an alternative for supercomputing-type processing. Linux versions of Linda and Paradise are currently used by several organizations, including Amaratta Hess, Paralogic, and Emory University.

Both development tools will be priced at $250, plus $100 per node, up to 50 nodes. When applications involve more than 50 nodes, pricing is discounted to $50 per node. Various training and support options are available.

“SCA has always been committed to supporting all platforms used in high-performance computing,” said Dr. Andrew Sherman, SCA vice president. “With the widespread use and acceptance of Linux, it was only natural that we’d extend our products to this platform.” In addition to availability at little or no cost, Linux proponents cite Internet security, performance, and easy availability of source code as several of its advantages.

Linda and Paradise facilitate the development parallel and distributed computing applications. Linda, introduced in 1987, was the first commercial product to implement virtual shared memory (VSM), facilitating the use of supercomputers and large workstation clusters. Linda technology is embedded into parallel versions of Gaussian applications, the computational methodology for which John Pople won the 1998 Nobel Prize in Chemistry. Paradise, a next-generation evolution of Linda and introduced in 1993, supports multiple VSMs and also includes features such as assigning tasks to available processors, balancing data loads, and restarting or reassigning tasks that have failed.

Linda and Paradise are used for applications requiring financial and risk analysis, computational chemistry and biology, seismic analysis, EDA, and fluid dynamics. SCA clients include Lexis-Nexis, Lehman Brothers, Enron, and Motorola.

“Many of the IT professionals who are interested in high-performance computing are the same ones who are interested in Linux,” said Wayne Threatt, vice president of sales and marketing for SCA. “We’re pleased to be able to meet their requests with these new product versions.”

About Scientific Computing Associates
Founded in 1980, SCIENTIFIC has pioneered the commercial use of parallel and distributed computing. Linda® software is a set of powerful extensions to C, C++, Fortran and Java that enables rapid development and deployment of parallel applications. Linda® is a coordination language which supplies the "glue" needed to cement many independent processes together into a single parallel program. Linda® provides a Virtual Shared Memory (VSM) that is logically shared by all the processes in a parallel program. Linda® is easy to use, even for users who are new to parallel computing. Proven applications include financial and risk analysis, computational chemistry and biotechnology, seismic analysis, electronic design (EDA), and computational fluid dynamics.
