La matière du sens : l'animation pensante de Garri Bardine
No full textInternational audienceGarri Bardine (born in 1941) is one of those rare directors of Russiananimated films of his generation who has remained very active, despite the financialconstraints that are particularly significant in this field. Already having twenty-fivefilms to his credit, he continues to create films that use the visual possibilities offered byall sorts of materials alongside a variety of musical realms to convey to the viewer ideas,which are dear to him. Themes of tolerance, the absurdity of war, life passing, socialsatire and an increasingly significant satire on post-Soviet society are realised thanks toa careful choice of techniques (at the start drawing, quickly abandoned, then modellingclay, puppets, use of string, miscellaneous objects etc.) and of music that sometimesdictates the rhythm of the work. In this way Bardine, a real all-rounder of animation,achieves films that reflect on the human condition.Garry Bardine (né en 1941) est l’un des rares réalisateurs de filmsd’animation russes de sa génération à continuer à faire des films, malgré lescontraintes financières particulièrement sensibles dans ce domaine. Ayant déjà àson actif vingt-cinq films, il continue de créer des films qui utilisent les possibilitésvisuelles qu’offrent toutes sortes de matières ainsi que des univers musicaux variéspour transmettre au spectateur des idées qui lui sont chères. Les thèmes de latolérance, de l’absurdité de la guerre, de la vie qui passe, la satire de moeurs et unesatire de la société postsoviétique de plus en plus sensible sont comme matérialisésgrâce à un choix précis de techniques (au début dessin, vite abandonné, puis pâteà modeler, poupées, utilisation de ficelle, d’objets divers, etc.) et des musiques quidictent même parfois le rythme de l’oeuvre. Bardine, véritable touche-à-tout del’animation, réalise ainsi des films réfléchissant sur la condition humaine.Гарри Бардин (родился в 1941 году) один из тех немногихрежиссёров анимационного фильма его поколения, кто остаётся творческидеятельным, вопреки бремени финансовых ограничений, особенно чувствительныхв этой области.

Time efficiency of CT colonography: 2D vs 3D visualization
No full textWe aimed to compare the time efficiency of three visualization methods in CT colonography and to identify the colonic factors influencing the time for interpretation. Twenty CT colonographic examinations were prospectively analysed. Three reading methods were adopted: method 1, primary 2D analysis with the use of virtual endoscopy as problem solver, method 2, primary standard virtual endoscopy with semiautomatic navigation through the colon and use of 2D images as problem solver; method 3, primary virtual endoscopy with automatic navigation and the use of 2D images as problem solver. In method 1, time for 2D analysis ranged between 6 and 18 min (mean 12) for evaluation of both supine and prone decubitus with a synchronization method. In method 2, time for 3D manual navigation in supine plus prone ranged between 9 and 24 min (mean 17). In method 3, time for automated navigation ranged between 6 and 20 min (mean 12) for evaluation of both supine and prone decubitus. A statistically significant difference was found between time efficiency of methods 1 and 2 (p=0.009, t-test, unequal variances). Methods 2 and 3 showed a tendency to significant differences (p=0.054, t-test, unequal variances). Faecal or fluid residuals were reported as major drawbacks in 3D navigations, requiring constant correlation with 2D images; tortuous folds influenced mostly the 2D analysis; diverticula were reported as influencing factor in all three methods. No differences in sensitivity and specificity were observed between the three viewing methods. The 3D semiautomatic navigation method* tended to increase the time for interpretation in almost all cases. There is, in particular, greatest time efficiency for 2D analysis as compared with 3D manual analysis. Two-dimensional and automated 3D navigation reading have comparable time efficiencies in a routine clinical setting
Energy Behaviour of NUCA caches in CMPs
No full textAbstract—Advances in technology of semiconductor make
nowadays possible to design Chip Multiprocessor Systems equipped with huge on-chip Last Level Caches. Due to the wire delay problem, the use of traditional cache memories with a uniform access time would result in unacceptable response latencies. NUCA (Non Uniform Cache Access) architecture has been proposed as a viable solution to hide the adverse impact of wires delay on performance. Many previous studies have focused on the effectiveness of NUCA architectures, but the study of the energy and power aspects of NUCA caches is still limited.
In this work, we present an energy model specifically suited for NUCA-based CMP systems, together with a methodology to employ the model to evaluate the NUCA energy consumption. Moreover, we present a performance and energy dissipation analysis for two 8-core CMP systems with an S-NUCA and a D-NUCA, respectively. Experimental results show that, similarly to the monolithic processor, the static power also dominates the total power budget in the CMP system
Analysis of Static and Dynamic Energy Consumptions in NUCA Caches: Initial Results
No full textABSTRACT
NUCA caches are large L2 on-chip cache memories characterized by multi-bank partitioning and designed to hide wire delay effects. They exhibit high hit rates while keeping access latency low. Proposed designs for such caches are Static NUCA, in which data are statically allocated to the cache banks, and Dynamic NUCA, in which data may reside in different banks, and a migration mechanism is introduced to better tolerate wire delay
effects. The two architectures permit to achieve different performances by acting on architectural parameters and data management policies, at the cost of different balances between
static and dynamic power consumption and energy dissipation. In this work, we propose preliminary results of the characterization
of such balances, by presenting an evaluation of performance and energy consumption of conventional UCAs, and Static and Dynamic NUCA caches. All the considered caches architectures are equal sized and they are supposed to be used in an aggressive
high frequency system running some applications from the SPEC CPU2000 and the NAS Parallel Benchmarks suites. The experimental results obtained indicate that, although the migration
of data contributes to increase the dynamic energy consumption in Dynamic NUCA caches, the higher IPC achieved permits to save
static energy, which dominates the power/energy balance in all the considered architectures. As a consequence, such results
would designate NUCA caches as the most performing and
energy saving architectures. Besides, according to the obtained results, future power improvements for NUCA caches should concentrate on static energy, while, for the dynamic energy, the on-chip network is the most critical element. Migration of data is
acceptable, since it has a positive impact on performance, and the
increased dynamic energy is overwhelmed by the static energy savings resulting from the shorter execution time. In order to give a general validity to such statements, we need to explore more
design space points for each architecture (by varying the running clock rate and other design parameters) and to evaluate them considering a larger set of benchmark
