cnofm

Juror Selection Programs
In choosing a jury panel, one wishes to randomly and fairly select N jurors out of a pool of M names, where M is usually much larger than N. "Fairly" means that all combinations of N jurors should be equally likely to be chosen. Sample software for this problem was developed in June of 1994 at the request of the Administrative Office of the U.S. Courts. The software was included in a Request for Proposals for a turnkey system for jury selection. Except for very minor changes, these are the same as the 1994 versions. The algorithms are suitable for juror pools of any reasonable size (the upper limit is over two billion jurors).

DIVERSE

DIVERSE is a cross-platform, open source, API for developing virtual reality applications. We have developed two sets of software to enhance its capabilities. There is a set of DIVERSE applications, including TIM (Things In Motion) to visualize time-series positional data, and XWand, to transmit data from shared memory into X windows mouse events. There is also a set of DIVERSE DSOs (Dynamic Shared Objects), separately compiled functionality that can be linked into a visualization program. These include functionality for isolating and moving individual objects within a visualization, and for interaction between applications and visualization programs.

IMPI

The IMPI (Interoperable MPI) tester is an on-line service for testing compliance of an MPI library with the IMPI specification. IMPI is a set of protocols, implemented within an MPI library, that allow two or more MPI libraries to operate as a single MPI library that spans two or more separately administered parallel computers. Any developer of an MPI library that will include IMPI support can use this tester during development to verify that their library will interoperate with other IMPI enabled MPI libraries. This tester is accessed over the Internet, using a simple Java applet for the user interface, and is implemented in Java to mimic one or more remote clusters running IMPI/MPI. The IMPI tester includes a set of tests that exercise each of the IMPI protocols, communicating with the user's cluster over TCP/IP sockets, and returns pass/fail results to the user.

PADE

PADE is a flexible, customizable environment for developing parallel applications that use the Parallel Virtual Machine (PVM) message-passing library. It provides an integrated framework for all phases of development of a message-passing parallel application: editing, compilation, execution, and performance monitoring and enhancement. The PADE package consists of an intuitive graphical user interface, a suite of PVM utilities, and extensive documentation in PostScript, ASCII, and HTML formats. PADE is most useful with a heterogeneous virtual machine consisting of multiple architectures and/or multiple file systems where it aids the parallel developer by helping to keep track of which source files must be sent and compiled on which hosts, sending the files, issuing the compilation commands, and displaying the results of the compilation on the developer's terminal

WebSubmit

WebSubmit is a Web-based utility providing access to applications on a collection of heterogeneous computing resources. Its goal is to make it easy to use computing resources via the Web without requiring knowledge of the specifics of unfamiliar operating systems and dynamic application environments. Users can effectively log into distinct computing environments and perform tasks without needing a detailed knowledge of their operating environment. A collection of machines, referred to as the cluster and determined by the site administrators, can be accessed through WebSubmit. Strong authentication using the Secure Sockets Layer protocol lets registered users connect to the system, and when validated by a WebSubmit authority, gives them access to a group of application modules. Each application module is presented as an HTML form; this form is filled out and submitted to the server, which then processes the request and executes the desired tasks on the specified remote system using another secure protocol. The system is flexible and extensible, and its modularity promotes ease of use, maintainability, and interface development.

MCSD staff have contributed to the development of Zoltan, which was developed at Sandia National Laboratories.
