Abstract
The physical data of the Large Helical Device (LHD) project have been serviced by the Analyzed Data Server system, and approximately 600 kinds of physical data are served. In order to execute simulation programs for the LHD experiment, one must gather sets of physical data. Because the Automatic Analyzed Server (AutoAna) calculates the physical data automatically, it eases the scientist’s task of collecting these physical data. The AutoAna has provided better computing environments for the scientists. Thus, the scientists, having recognized its benefits, make various requests as issues arise. In this paper, the authors introduce the current status of the AutoAna system.
Highlights
Typical LHD plasma experiments are executed as repetitive short-pulse experiments
The goal of AutoAna is to provide the complete physical data set. Scientists can replace their analysis program in order to reflect their new study, and all the dependent data is quickly recalculated by replacement of the programs
In order to allow the researchers to replace their program by themselves, the program must be run in an isolated environment
Summary
Typical LHD plasma experiments are executed as repetitive short-pulse experiments. These last for a relatively short time, for example, 10 seconds or less. In order to launch the calculation program automatically, and to maintain the dependencies among the data, the authors have developed the AutoAna. During the consecutive short pulse experiments, the AutoAna provides the latest data soon after the discharge ends by executing the analysis program automatically. AutoAna provides the necessary data to run simulation programs, such as transport analyses. The AutoAna has contributed the useful data analysis environments to scientists.
