System-wide data management for General Atomic's Doublet III distributed computer system
A continual increase in diagnostic data has yielded four problems which must be addressed and solved for the future: (1) the acquisition and processing of the large mass of data must be performed in a limited time frame and must extract and present in a useful manner a summary of information to permit intelligent experimental direction; (2) all diagnostic data for the life of an experiment must be archived with the ability to retrieve and analyze old or new data; (3) the data structures must be standardized to allow for exchanges of data internally within a laboratory and externally between laboratories. Fewer devices are being built with larger demands for data acquisition and analysis; and (4) the methods of accessing and analyzing data must be standardized between computing systems providing better utilization of an experimentalist's time and energy. General Atomic's Doublet III tokamak fusion experiment has addressed these problems utilizing a system-wide data base structure spanning multiple levels of computer processing. Presented in this paper are methods over these multiple levels of computer processing for standardizing the diagnostic data structures, standardizing the methods for accessing the data and providing the transferability of analysis tasks.
