Coupled Simulations in Plasma Physics with the Integrated Plasma Simulator Platform

Abstract

Simulations of fusion plasma obtained in a Tokamak device can involve a wide range of physics phenomena occurring at different scales. Programming such a simulation is challenging and tends to increase the complexity of the code and its maintenance. Many approaches are trying to alleviate this issue by coupling several single scale components, the complexity being moved from the physics code to the coupling and execution platform. In this paper we are presenting the Integrated Plasma Simulator (IPS) platform, its advantages for running efficiently coupled simulations for different plasma physics use cases and are briefly comparing it to other platforms used in the fusion community.

Application of the extreme scaling computing pattern on multiscale fusion plasma modelling

“…Since we are more interested in high performance computing rather than the ease of design (lego blocks, graphical interface, Java), we decide to replace (iii) with MUSCLE2. Implementing MUSCLE2 components from existing codes that are previously called from a component in Kepler is made easier by strictly following the generic approach detailed in [18], for which a modular and non-intrusive implementation is based on a hierarchy of interchangeable wrappers. The structure of a standard MUSCLE2 kernel is given in Listing 1, where Din/Dout are the input and output data, and Pin/Pout are the names of the input and output ports, respectively.…”

Towards a Uml Profile for the Simulation Domain

“…Domains where simulation is widely used are numerous: Physics, biology, medicine, and others. Integrated Plasma Simulator (IPS) platform [13], and Virtual Imaging Platform (VPM) [25] are respectively simulation platforms dedicated to the plasma physics and medical imaging domains. Due to the profusion of concepts, methods, frameworks and tools related to the modelling and simulation field, we present in the following a synthesis addressing advanced issues relevant to this field.…”

“…The wrappers are pieces of code that embodies the simulation code of single experiments. For instance the layered architecture of the Integrated Plasma simulation platform described in [13] distinguishes between data wrappers and coupling wrappers:…”

“…Scientific workflows Management Systems have been developed during the last two decades. They are intended to manage, enact and monitor scientific workflows which are a composition of a series of computation and/or data manipulation [13]. Scientific workflows are enacted and orchestrated by specific engines, called workflow engines, forming the core components of scientific workflows Management Systems.…”
