“…For example, if a specific application is approximated based on a set of benchmarks and weighting factors, then the best system for the application from among different systems can be suggested based on the benchmark results and weighting factors. Moreover, since the SSSP metric can be approximated to the SSP metric instances of various workload sets, it can be used to evaluate various middleware, system software, virtual environments, and tools such as failure detection and fault tolerance in distributed systems [16], error correction in a virtual environment [19], and so on.…”

Because of the increasing complexities of systems and applications, the performance of many traditional HPC benchmarks, such as HPL or HPCG, no longer correlates strongly with the actual performance of real applications. To address the discrepancy between simple benchmarks and real applications, and to better understand the application performance of systems, some metrics use a set of either real applications or mini applications. In particular, the Sustained System Performance (SSP) metric Kramer et al. (The NERSC sustained system performance (SSP) metric. Tech Rep LBNL-58868, 2005), which indicates the expected throughput of different applications executing with different datasets, is widely used. Whereas such a metric should lead to direct insights on the actual performance of real applications, sometimes more effort is necessary to port and evaluate complex applications. In this study, to obtain the approximate performance of SSP representing real applications, without running real applications, we propose a metric called the Simplified Sustained System Performance (SSSP) metric, which is computed based on several benchmark scores and their respective weighting factors, and we construct a method evaluating the SSSP metric of a system. The weighting factors are obtained by minimizing the gap between the SSP and SSSP scores based on a small set of reference systems. We evaluated the applicability of the SSSP method using eight systems and demonstrated that our proposed SSSP metrics produce appropriate performance projections of the SSP metrics of these systems, even when we adopted a simple method for computing the weighting factors. Additionally, the robustness of our SSSP metric was confirmed via computation of the weighting factors based on a smaller set of reference systems and computation of the SSSP metrics of other systems.

“…Traditional animation uses frame-byframe drawing in the form of art for spatial representation. Although both are spatiotemporal integrated arts, the film is constructed on the basis of reality while the animation is constructed on the basis of assumption [26]. Compared with film, animation is closer to the expression of literature and art.…”

Animation art design is widely used in all levels of social life and has become an important part of modern social visual culture. Driven by new technologies, it is integrated with relevant application fields, resulting in new media forms and art categories. The development course of animation art design is sorted out, focusing on the analysis of the technical basis of animation art design and art form, social function and cultural form, creative practice, and theoretical research. This paper puts forward the concept of dimension composition of animation art design and analyzes and studies the dimensions of technology and art, cognition and experience, economy, and culture in animation art design and artistic creation based on this concept. The modeling of edge devices and services is proposed to abstract resources and provide a unified formal description of user virtual perception for animation art design of various sensing types. All related attributes are described uniformly, and the device model and task model are given. Users can customize services based on predefined attributes. According to the development demand of multiuser shared virtual environments, the characteristics and limitations of the previous perception management scheme are analyzed and a two-layer perception management scheme is designed to adapt to the development of new multiuser shared virtual environment of animation art design.
