It is now well known that edge localized modes (ELMS) lead to the ejection of a number of filamentary structures into the scrape-off layer (SOL). ELMS thus generate structures with excess energy and density. Recent results show that ELM filaments also carry current. Furthermore it can be conjectured that ELM filaments leave corresponding holes behind. If such a hole is able to reach a resonant magnetic surface it may close on itself and thus increase its lifetime significantly, thereby becoming detectable. We presume that the Palm Tree Mode (PTM) is a signature of such an event. Understanding PTMs therefore enhances our knowledge of ELMs and edge physics and contributes to the verification of ELM models. (C) 2011 Elsevier B.V. All rights reserved.

the battle of fixed function devices vs. programmable devices has been won by the programmables. the question facing us now is to determine what kinds of programmability to place on next generation systems/devices. Research and development on many applications has shown that different kinds of hardware and software programmability succeed for different application classes: powerful, singlethread-optimized CPUs continue to do very well for many applications; the General Purpose GPU is carving a niche in high throughput, parallel floating point codes in addition to its home turf of graphics; the FPGA is particularly good at variable bit-size computations and data steering, as well as parallel distributed control of networks. Future systems may well need all three types of these types of engines, and perhaps interesting mixtures of them. this is particularly true when we deal withthe combined goals of optimizing cost, performance and *** this workshop, we will look to the future of the FPGA within these types of 'converged' programmable computing engines, and reflectively ask ourselves: What role can the FPGA play? What future applications in areas such as networking, mobile, and artificial intelligence can be driven by FPGAs? How do FPGAs fit into the architecture realm of CPUs, general purpose GPUs, and DSPs? How should the designer/programme express their intent in the most effective way possible? What are the requirements for a compilation and optimization environment that allow FPGAs to intermix within a heterogeneous and converged future?the intent of this workshop is to open a discussion on these questions. there will be a series of short, invited talks interspersed with free and open discussion.
