In this paper we present how Intel's Single-Chip-Cloud processor behaves for parallel macro pipeline applications. Subsets of the SCC's available cores can be arranged as a pipeline where each core processes one stage of the overall workload. Each of the independent cores processes a small part of a larger task and feeds the following core with new data after it finishes its work. Our case-study is a parallel rendering system which renders successive images and applies different filters on them. On normal graphics adapters this is usually done in multiple cycles, we do this in a single pipeline pass. We show that we can achieve a significant speedup by using multiple parallel pipelines on the SCC. We show that we can further improve performance by using SCC's controlling PC in conjunction with the SCC. We also identify aspects of the SCC that hinder the overall performance, mainly the lack of local memory banks for each core on the SCC. the results presented in this paper are not limited to only image processing, but users could expect similar experiences where macro pipelining is used in other applications on the SCC. © 2013 IEEE.

In this paper, a collaboration support system for 3D shape evaluation by using network virtual reality is proposed on the basis of both studies in 31) shape evaluation and communication support in virtual space. Collaboration mainly consists of two tasks;one is each partner's task that is performed by the individual, the other is communication with each other. Both of them are very important objectives for all the collaboration support system. the proposed system provides the two viewpoints for each task. One is the viewpoint of back side of user's own avatar for the smooth communication. the other is that of avatar's eye for 3D shape evaluation. Switching the viewpoints satisfies the task conditions for 3D shape evaluation and communication. the system basically consists of PC, HMD and sensors, and users can share the embodied interaction by observing interaction between their avatars in virtual space. However, the HMD and magnetic sensors, which are put on the users, would restrict the nonverbal communication. then, we have tried to compensate the loss of nodding of partner's avatar by introducing the speech-driven embodied interactive actor InterActor. Sensory evaluation by paired comparison of 31) shapes in the collaborative situation in virtual space and in real space and the questionnaire are performed. the result demonstrates the effectiveness of InterActor's nodding in the collaborative situation.

Modern GPUs are gradually used by more and more cluster computing systems as the high performance computing units due to their outstanding computational power, whereas bringing system-level (among different nodes) architectural heterogeneity to cluster. In this paper, based on MPI and CUDA programming model, we aim to investigate task scheduling for GPU heterogeneous cluster by taking into account the system-level heterogeneous characteristics and also involving the weights of the processor (both CPUs and GPUs). At first, based on our GPU heterogeneous cluster, we classify executing tasks to six major classifications according to their parallelism degrees, input data sizes, and processing workloads. then, aiming to realize the approximately optimal mapping between tasks and computing resources, a task scheduling strategy is presented. In this paper, we present the WSLSA greedy heuristic which can involve the weights of the processor. Besides, we also define two measurement factors for the task assignments. One is the maximum value of total workloads for all task assignments to consider the maximum workloads for the GPU heterogeneity cluster. the other is the distribution of task assignments which can determine the load balance of the task assignments for the GPU heterogeneity cluster. the other is the distribution of task assignments which can determine the load balance of the task assignments for the GPU heterogeneity cluster. © 2013 IEEE.

Due to the simplicity and high efficiency, composited finite element method(CFEM) based virtual cutting attracted much attention in the field of virtual surgery in recent years. Even great progress has been made in volumetric cutting of deformable bodies, there are still several open problems restricting its applications in practical surgical simulator. First among them is cutting fracture modelling. Recent methods would produce cutting surface immediately after an intersection between the cutting plane and the object. But in real cutting, biological tissue would first deform under the external force induced by scalpel and then fracture occurs when the stress exceeds a threshold. Secondly, it's computation-intensive to reconstruct cutting surface highly consistent with the scalpel trajectory, since reconstructed cutting surface in CFEM-based virtual cutting simulation is grid-dependent and the accuracy of cutting surface is proportional to the grid resolution. this paper propose a virtual cutting method based on CFEM which can effectively simulate cutting fracture in a biomechanically and visually plausible way and generate cutting surface which is consistent with the scalpel trajectory with a low resolution finite element grid. We model this realistic cutting as a deformation-fracture repeating process. In deformation stage, the object will deform along with the scalpel motion, while in the fracture stage cutting happens and a cutting surface will be generated from the scalpel trajectory. A delayed fracturing criteria is proposed to determine when and how the cutting fracture occurs and an influence domain adaptation method is employed to generate accurate cutting surface in both procedures of deformation and fracture. Experiments show that our method can realistically simulate volumetric cutting of deformable bodies and efficiently generate accurate cutting surface thus facilitating interactive applications. © 2019 the Author(s) Eurographics proceedings © 2019 the

An increasingly large number of users connect to virtual worlds on a regular basis to conduct activities ranging from gaming to business meetings. In all these worlds, users project themselves into the environment via an avatar: A 3D body which they control and whose appearance is often customizable. However, considering the prevalence of this form of embodiment, there is a surprising lack of data about how and why users customize their avatar, as well as how easy and satisfying the existing avatar creation tools are. In this paper, we report on a study investigating these issues through a questionnaire administered to more than a hundred users of three virtual worlds offering widely different avatar creation and customization systems (Maple Story, World of Warcraft, and Second Life). We illustrate the often-surprising choices users make when creating their digital representation and discuss the impact of our findings for the design of future avatar creation systems.

this paper documents the applicability of electrical and electronics graphics to introductory general engineering graphics curricula. It includes an overview of the architectural, mechanical and electrical/electronic graphics language. the electrical/electronic field is the largest branch of engineering and continues to grow. this dynamically changing field interfaces with architectural, civil, mechanical, industrial, computer and the many other disciplines of engineering. A common, seamless and interrelated graphics language is used to prepare drawings and diagrams by engineering design groups. Electrical/electronic graphics is frequently overlooked in introductory engineering graphics courses and texts. Electrical and electronic graphics is part of the universal engineering graphic language used to prepare, read and interpret plans, and should be included in engineering and related curricula. this paper describes how electrical/electronic graphics can be incorporated to effectively introduce students to design, creative thinking, visualization and the understanding of the widely used graphics language.

Recently, GPU libraries have made it easy to improve application performance by offloading computation to the GPU. However, using such libraries introduces the complexity of manually handling explicit data movements between GPU and CPU memory spaces. Unfortunately, when using these libraries with complex applications, it is very difficult to optimize CPU-GPU communication between multiple kernel invocations to avoid redundant communication. In this paper, we introduce SemCache, a semantics-aware GPU cache that automatically manages CPU-GPU communication and dynamically optimizes communication by eliminating redundant transfers using caching. Its key feature is the use of library semantics to determine the appropriate caching granularity for a given offloaded library (e.g., matrices in BLAS). We applied SemCache to BLAS libraries to provide a GPU drop-in replacement library which handles communications and optimizations automatically. Our caching technique is efficient;it only tracks matrices instead of tracking every memory access at fine granularity. Experimental results show that our system can dramatically reduce redundant communication for real-world computational science application and deliver significant performance improvements, beating GPU-based implementations like CULA and CUBLAS. © 2013 ACM.
