Performance of the ITER is anticipated to be highly sensitive to the edge plasma condition. The edge pedestal in ITER needs to be predicted from an integrated simulation of the necessary first-principles, multi-scale physics codes. The mission of the SciDAC Fusion Simulation Project (FSP) Prototype Center for Plasma Edge Simulation (CPES) is to deliver such(More)
A new predictive computer simulation tool targeting the development of the H-mode pedestal at the plasma edge in tokamaks and the triggering and dynamics of edge localized modes (ELMs) is presented in this report. This tool brings together, in a coordinated and effective manner, several first-principles physics simulation codes, stability analysis packages,(More)
A major responsibility of any Quality Assurance Unit (QUA) is to ensure data integrity. Errors made during data entry can lead to many problems in the study review process and decrease the quality, accuracy, and overall efficiency of data management. One technique that can reduce the number of data entry errors in computer data sets is the use of a dual(More)
The design and efficient operation of a distributed information system to support scientific modeling is subject to a variety of balancing concerns, such as conlputa-tion, data, and communication) load and constraints on the use of restricted-license third-party software conlpo-Ilents, special purpose 1/0 devices, and large data resources. The Regional(More)
(such as the point on the surface where the centre of a vortex touches down) and saddles 23,27 (which have two streamlines entering and two leaving the critical point from opposite directions). Saddle points are thought to be characteristic of separated flows 21–24. The distribution of critical points, and of the streamlines joining them, defines the(More)
A broad partnership of institutions is collaborating in developing and demonstrating the performance and application of eddy-resolving, real-time global and basin-scale ocean prediction systems using the HYbrid Coordinate Ocean Model (HYCOM). These systems are to be transitioned for operational use by the U. systems will run efficiently on a variety of(More)
