MDSplus yesterday, today and tomorrow
No full textMDSplus is a data acquisition and analysis system used worldwide predominantly in the fusion research community. Development began 31 years ago by a collaboration of software developers who were charged with providing a data acquisition system for three new fusion experiments under construction: CMOD at MIT, ZTH at LANL and RFX at Padova, Italy. The design of MDSplus combined the functionality of MDS (MIT/Model Data System developed at MIT for the Alcator and Tara fusion experiments) with new features suggested by the developers from the other laboratories. The development of MDSplus used a RAD (rapid application development) approach before RAD became a mainstream methodology. MDSplus was implemented and ready for the initial operation of CMOD in 1991. Since that time, many other fusion facilities started using MDSplus for data acquisition and/or for exporting their data to other sites. Today MDSplus is still used around the world for fusion energy research, space exploration and other fields of science and technology. Work on MDSplus continues to enhance its capabilities, support more platforms, and improve its reliability. It is anticipated that MDSplus will continue to provide valuable tools for the fusion energy research community. This paper describes some of the history of the MDSplus software, the work that is currently underway, and the plans to enable MDSplus to continue to be available and supported long into the future

MDSplus remote data access over high latency connections
No full textRemote data access is a mandatory requirement for large devices operated by international teams. Data acquired during experimental sessions should be soon available at remote sites for on-line analysis and visualization. Network channel capacity plays an important role, but overall performance depends also on the strategies adopted by the data system in order to optimize data transfer, increasing throughput and reducing latency. The ITER Remote Experimentation Centre (REC) in Rokkasho is one of the projects currently implemented within the Broader Approach agreement. The ultimate objective of the REC is to allow researchers to take part in the experimentation on ITER from a remote location. The technologies developed for the REC include Remote Data Access (RDA) tools, which allows the users to access to the experimental data, regardless of their geographical location. MDSplus is the most widespread data system that is used in the fusion community for remote data access and is the candidate technology for exporting ITER data at the REC. This paper reports the measured performance in remote data access between Europe and Japan using MDSplus and describes several strategies that have been adopted in order to optimize data transfer. The solutions recently implemented within MDSplus for data streaming and remote access of very large signals are also discussed, as they represent important features needed for RDA in large experiments
