Geekbench is one of the most referenced cross-platform benchmarks in the mobile world. Most of its workloads are synthetic but some of them aim to simulate real-world behavior. In the mobile world, its microarchitectural behavior has been reported rarely since the hardware profiling features are limited to the public. As a popular mobile performance workload, it is hard to find Geekbench’s microarchitecture characteristics in mobile devices. In this paper, a thorough experimental study of Geekbench performance characterization is reported with detailed performance metrics. This study also identifies mobile system on chip (SoC) microarchitecture impacts, such as the cache subsystem, instruction-level parallelism, and branch performance. After the study, we could understand the bottleneck of workloads, especially in the cache sub-system. This means that the change of data set size directly impacts performance score significantly in some systems and will ruin the fairness of the CPU benchmark. In the experiment, Samsung’s Exynos9820-based platform was used as the tested device with Android Native Development Kit (NDK) built binaries. The Exynos9820 is a superscalar processor capable of dual issuing some instructions. To help performance analysis, we enable the capability to collect performance events with performance monitoring unit (PMU) registers. The PMU is a set of hardware performance counters which are built into microprocessors to store the counts of hardware-related activities. Throughout the experiment, functional and microarchitectural performance profiles were fully studied. This paper describes the details of the mobile performance studies above. In our experiment, the ARM DS5 tool was used for collecting runtime PMU profiles including OS-level performance data. After the comparative study is completed, users will understand more about the mobile architecture behavior, and this will help to evaluate which benchmark is preferable for fair performance comparison.

Film and performance have always been closely interconnected, from the origins of cinematic projection in 1895. This essay, with a theoretical focus, explores how film and moving-image forms work to transform performance when they intersect with it, and vice versa. It examines how film serves to mediate and ‘reframe’ the experience and the time of live performance events, notably through the incorporation of moving-image elements into the space of performance, and through particular forms of projection and audience perception. It also probes how conceptions of intermediality can be traced specifically through the intersection of film and performance. The essay spans the entirety of moving image culture, beginning with an account of the connections between film and performance in the work of the German innovators of moving-image projection, the Skladanowsky Brothers, and ending with an examination of the work of the contemporary Lebanese filmmaker and performance artist, Rabih Mroué, whose work resonates with early cinema’s performative strategies but focuses also on current digital media events such as the dangerous ‘performative’ public filming with iPhones of government snipers in the streets of Syria.

Wolfgang Mitterer (1958--) is an Austrian composer and organist noted for his work with live electronics and improvisation. Born on 6 June, 1958 in Lienz, East Tyrol, Mitterer studied organ and composition at the University of Music and the Performing Arts Vienna, followed by a year-long residency at the studio for electroacoustic music (EMS) in Stockholm. An exceptionally prolific composer, Mitterer’s output spans a staggeringly broad range of approaches to music making, including works for tape, chamber music of various formations, experimental pop songs (Sopop), works for large orchestra, music for theatre and opera, music for film, and sprawling site-specific installations and performance events (turmbau zu babel, for example, is scored for 4,200 singers, 22 drums, 48 brass players, and 8-channel tape). His works list includes over 200 entries and demonstrates a particularly catholic, pluralistic, non-dogmatic approach to instrumentation, duration, venue, scale, and function. Despite this diversity, Mitterer’s work maintains several important central tendencies: stylistically, the music is often characterized by layers of crackles, twitches, clicks, and pops (both electronic and acoustic), with a rustling, flickering, chirping, gestural energy. These more fragmented, granular layers are quite often combined with gradual, elongated, atmospheric, and lyrical material, though generally a sense of instability and unpredictability remains.

Textuality in antiquity differs significantly from that of modern Western culture in which the text exists as a fixed, idealized abstraction. In antiquity reading was speaking, and stichography is a visual representation of this interface between speech and writing. Stichography’s spatialization displays scribes’ perception of the spoken text including the concomitants of oral performance. Stichography also reflects scribes’ attentiveness to the readership’s experience with the performed or inscribed text. Scribes interacted with compositions as authors, adapting them according to the exigencies of specific performance events. As a result, the transmission of a specific written layout can supersede parallelismus membrorum; nevertheless, parallelism is a constitutive device in the majority of stichographic texts. The demarcation of sense units elicits two symbiotic social uses, both of which are also implied by the content of the canon. Stichographic texts provide a formatted reference point that is styled to facilitate oral performance and pedagogy.

Abstract Orality/aurality is recognised by a growing number of scholars as a significant aspect of the context of New Testament texts. As part of the exploration of the oral features of New Testament texts some are turning to Greco-Roman storytelling and oratory, informed by performance studies. A selection of these explorations are discussed to introduce scholarship that attempts to identify various elements of performance events in the early church as a basis for re-thinking our ways of studying and our interpretations of the New Testament writings in their original context. The obstacles to such efforts are considerable, but some significant gains have been made. Focusing on research on the Gospel of Mark, this discussion shows how performance critical studies allow new insights into the origins of the Gospels, leading to interesting new and meaningful perspectives on the history of the early Jesus movement with specific attention to the role telling and presenting the Markan story played.
