New applications of Equinox code for real-time plasma equilibrium and profile reconstruction for tokamaks

Recent development of real-time equilibrium code Equinox [1] using a fixed-point algorithm [2] allow major plasma magnetic parameters to be identified in real-time, using rigorous analytical method. The code relies on the boundary flux code providing flux values on the first wall of vacuum vessel. By means of least-square minimization of differences between magnetic field obtained from previous solution and the next measurements the code identifies the source term of the non-linear Grad-Shafranov equation [3]. The strict use of analytical equations together with a flexible algorithm offers an opportunity to include new measurements into stable magnetic equilibrium code and compare the results directly between several tokamaks while maintaining the same physical model (i.e. no iron model is necessary inside the equilibrium code). The successful implementation of this equilibrium code for JET and Tore Supra have been already published [1], in this paper, we show the preliminary results of predictive runs of the Equinox code using the ITER geometry.Comment: 12th International Congress on Plasma Physics, 25-29 October 2004, Nice (France

Anharmonicity due to Electron-Phonon Coupling in Magnetite

We present the results of inelastic x-ray scattering for magnetite and analyze the energies and spectral widths of the phonon modes with different symmetries in a broad range of temperature 125<T<293 K. The phonon modes with X_4 and Delta_5 symmetries broaden in a nonlinear way with decreasing temperature when the Verwey transition is approached. It is found that the maxima of phonon widths occur away from high-symmetry points which indicates the incommensurate character of critical fluctuations. Strong phonon anharmonicity induced by electron-phonon coupling is discovered within ab initio calculations which take into account local Coulomb interactions at Fe ions. It (i) explains observed anomalous phonon broadening, and (ii) demonstrates that the Verwey transition is a cooperative phenomenon which involves a wide spectrum of phonons coupled to charge fluctuations condensing in the low-symmetry phase.Comment: 5 pages, 5 figures, accepted in Physical Review Letter

Short-Range Correlations in Magnetite above the Verwey Temperature

Magnetite, Fe$_3$O$_4$, is the first magnetic material discovered and utilized by mankind in Ancient Greece, yet it still attracts attention due to its puzzling properties. This is largely due to the quest for a full and coherent understanding of the Verwey transition that occurs at $T_V=124$ K and is associated with a drop of electric conductivity and a complex structural phase transition. A recent detailed analysis of the structure, based on single crystal diffraction, suggests that the electron localization pattern contains linear three-Fe-site units, the so-called trimerons. Here we show that whatever the electron localization pattern is, it partially survives up to room temperature as short-range correlations in the high-temperature cubic phase, easily discernible by diffuse scattering. Additionally, {\it ab initio} electronic structure calculations reveal that characteristic features in these diffuse scattering patterns can be correlated with the Fermi surface topology.Comment: 7 pages, 6 figure

The ESCAPE project : Energy-efficient Scalable Algorithms for Weather Prediction at Exascale

In the simulation of complex multi-scale flows arising in weather and climate modelling, one of the biggest challenges is to satisfy strict service requirements in terms of time to solution and to satisfy budgetary constraints in terms of energy to solution, without compromising the accuracy and stability of the application. These simulations require algorithms that minimise the energy footprint along with the time required to produce a solution, maintain the physically required level of accuracy, are numerically stable, and are resilient in case of hardware failure. The European Centre for Medium-Range Weather Forecasts (ECMWF) led the ESCAPE (Energy-efficient Scalable Algorithms for Weather Prediction at Exascale) project, funded by Horizon 2020 (H2020) under the FET-HPC (Future and Emerging Technologies in High Performance Computing) initiative. The goal of ESCAPE was to develop a sustainable strategy to evolve weather and climate prediction models to next-generation computing technologies. The project partners incorporate the expertise of leading European regional forecasting consortia, university research, experienced high-performance computing centres, and hardware vendors. This paper presents an overview of the ESCAPE strategy: (i) identify domain-specific key algorithmic motifs in weather prediction and climate models (which we term Weather & Climate Dwarfs), (ii) categorise them in terms of computational and communication patterns while (iii) adapting them to different hardware architectures with alternative programming models, (iv) analyse the challenges in optimising, and (v) find alternative algorithms for the same scheme. The participating weather prediction models are the following: IFS (Integrated Forecasting System); ALARO, a combination of AROME (Application de la Recherche a l'Operationnel a Meso-Echelle) and ALADIN (Aire Limitee Adaptation Dynamique Developpement International); and COSMO-EULAG, a combination of COSMO (Consortium for Small-scale Modeling) and EULAG (Eulerian and semi-Lagrangian fluid solver). For many of the weather and climate dwarfs ESCAPE provides prototype implementations on different hardware architectures (mainly Intel Skylake CPUs, NVIDIA GPUs, Intel Xeon Phi, Optalysys optical processor) with different programming models. The spectral transform dwarf represents a detailed example of the co-design cycle of an ESCAPE dwarf. The dwarf concept has proven to be extremely useful for the rapid prototyping of alternative algorithms and their interaction with hardware; e.g. the use of a domain-specific language (DSL). Manual adaptations have led to substantial accelerations of key algorithms in numerical weather prediction (NWP) but are not a general recipe for the performance portability of complex NWP models. Existing DSLs are found to require further evolution but are promising tools for achieving the latter. Measurements of energy and time to solution suggest that a future focus needs to be on exploiting the simultaneous use of all available resources in hybrid CPU-GPU arrangements

Foto-obrazy architektury: Fotografia jako medium referujące i projektujące architekturę

Praca recenzowana / peer-reviewed paperNiniejszy zbiór prac teoretycznych, fotoesejów i kronika studenckich konkursów fotograficznych organizowanych od 2008 roku na Wydziale Architektury i Sztuk Pięknych Krakowskiej Akademii im. Andrzeja Frycza Modrzewskiego, ma być zapisem refleksji związanych ze specyficzną, jak dotąd mało zbadaną a wszechobecną częścią teorii architektury, jaką jest fotografia. Jej szczególna odmiana ściśle związana ze sztuką budowania jest określana mianem fotografii architektonicznej, jednakże niniejsza monografia nie została tą definicją ograniczona.This book contains a selection of theoretical works and photo essays as well as a chronicle of photo competitions organised in the Faculty of Architecture and Fine Arts at Andrzej Frycz Modrzewski Krakow University since 2008, which is meant as the record of thoughts related to the specific, omnipresent though little examined so far, realm of the theory of architecture, i.e. photography. Its specific variant closely related to the building practice is called architectural photography. This monograph, however, is not restricted by means of the said definition and attempts at a slightly broader description of the phenomenon, reaching beyond its boundaries.Monografia powstała w ramach projektu badawczego nr WAiSP/DS/4/201

Abstract. In the simulation of complex multi-scale flows arising in weather and climate modelling, one of the biggest challenges is to satisfy strict service requirements in terms of time to solution and to satisfy budgetary constraints in terms of energy to solution, without compromising the accuracy and stability of the application. These simulations require algorithms that minimise the energy footprint along with the time required to produce a solution, maintain the physically required level of accuracy, are numerically stable, and are resilient in case of hardware failure. The European Centre for Medium-Range Weather Forecasts (ECMWF) led the ESCAPE (Energy-efficient Scalable Algorithms for Weather Prediction at Exascale) project, funded by Horizon 2020 (H2020) under the FET-HPC (Future and Emerging Technologies in High Performance Computing) initiative. The goal of ESCAPE was to develop a sustainable strategy to evolve weather and climate prediction models to next-generation computing technologies.

This paper presents an overview of the ESCAPE strategy: (i) identify domain-specific key algorithmic motifs in weather prediction and climate models (which we term Weather & Climate Dwarfs), (ii) categorise them in terms of computational and communication patterns while (iii) adapting them to different hardware architectures with alternative programming models, (iv) analyse the challenges in optimising, and (v) find alternative algorithms for the same scheme.

Oraviana in Polish Publications from 1989 to 2010

The thesis analyses Oravanian publications released in Poland from 1989 to 2010. In my research I used the following methods: bibliographic, textual analysis and criticism, as well as case study. The undertaken research into state-wide and regional bibliographies yielded information regarding the number of publishing houses and independent publishers involved in releasing books and magazines about Orava. All partakers of publishing efforts were engaged in diverse activities: associations, public and private endeavors. The implemented type of analysis of documents and their criticism, according to content and form, allowed me to present the history of major publishing houses and made it possible to characterize their literary output. Towarzystwo Przyjaciół Orawy (Friends of Orava Association), Muzeum - Orawski Park Etnograficzny w Zubrzycy Górnej (Museum – Ethnographic Museum of Orava in Zubrzyca Górna) and academic institutions of małopolska province deserve the most recognition for publishing efforts concerning the region. Priest Władysław Pilarczyk needs to be noted for having outstanding input into publishing numerous works covering Orava.Praca dotyczyła orawskich publikacji wydanych w polskim ruchu wydawniczym w latach 1989 – 2010. Posłużyłem się w niej następującymi metodami badawczymi: bibliograficzną, analizą i krytyką piśmiennictwa oraz studium przypadku. Badania nad zawartością ogólnopolskich i regionalnych bibliografii przyniosła informacje o liczbie domów wydawniczych i nieprofesjonalnych wydawców, zaangażowanych w produkcję książek i czasopism o Orawie. Odznaczały się oni różnym typem działalności: stowarzyszeniowym, państwowym i prywatnym. Zastosowana analiza i krytyka dokumentów pod względem treści i formy dała podstawy do przedstawienia historii najważniejszych wydawnictw oraz pozwoliła scharakteryzować ich dorobek. Najbardziej zasłużone wydawniczo dla regionu okazały się Towarzystwo Przyjaciół Orawy, Muzeum - Orawski Park Etnograficzny oraz instytucje akademickie z małopolski. Wybitnym wkładem dla powstania licznych orawskich publikacji odznaczył się ks. Władysław Pilarczyk
