“…The exchange of information between physics and engineering computing includes both data and events for program synchronization. Until now this has been done using 'C' programs, Unix-scripts, and an IPCS event system [7] running on a Solaris workstation. The 'C' programs used the EPICS CAC library to retrieve information from IOC records, and the MDSplus client library to write values to the nodes.…”

“…To support the special needs of NSTX's 'pulsed' operations, twenty 'C' programs and fifteen unix-scripts were written. These programs interface EPICS with other software that is used on NSTX, such as MDSplus data management and IPCS [3] interprocess messaging software.…”

Abstract--The NSTX achieved first plasma in 1999. The Experimental Physics and Industrial Control System (EPICS) is used to provide data-integration services for monitoring and control of all NSTX engineering subsystems. EPICS is a set of software initially developed at US DOE laboratories. It is currently used and maintained through a global collaboration of hundreds of scientists and engineers. This paper will relate some of our experiences using and supporting the EPICS software. Topics include reliability and maintainability, lessons learned, recently added engineering subsystems, new EPICS software tools, and a review of our first EPICS software upgrade. Steps to modernize the technical infrastructure of EPICS to ensure effective support for NSTX will also be described.

“…Distributed computing allows efficient data access from all sites, and each site can contribute to the processing of information during operations. Message passing using interprocess communications [6] (IPCS) developed at LLNL provides asynchronous communication among processes running in an heterogeneous, wide-area computing network [1]. Through IPCS messages, we coordinate analysis tasks and provide software access to the experiment's timing system to establish synchronization with the real-time operations.…”

Collaboration is an increasingly important aspect of physics research, particularly for complex and expensive experiments. Large experiments often rely on national or international teams of researchers to optimize goals and to provide greater use of facilities. Availability of highperformance workstations and fast, reliable wide-area networks affords the possibility of realizing "collaborative laboratories" comprising researchers and infrastructure widely dispersed geographically. We have developed a collaboratory supporting interactive research on a mainline scientific facility, the DIII-D tokamak experiment [5] (Figure 1). Distributed computations and data access provide resource sharing among institutions.
