IEEE symposium on high-performance computer architecture

作者： Ming Liu Tao Li Neo Jia Andy Currid Vladimir Troy Department of Electrical and Computer Engineering University of Florida NVIDIA

Pass-through techniques enable virtual machines to directly access hardware GPU resources in an exclusive mode, delivering extraordinary graphics performance for client users in GaaS clouds. However, the virtualization overheads of pass-through GPUs may decrease the frame rate of graphics workloads by reducing the occupancy rate of the GPU working queue. In this work, we make the first attempt to characterize pass-through GPUs running in different consolidation scenarios and uncover the root causes of these overheads. Towards this end, we set up state-of-the-art empirical platforms equipped with NVIDIA GRID GPUs and execute graphics intensive workloads running in GaaS clouds. We first demonstrate the existence of virtualization overheads, which can slow down the GPU command generation rate. Compared with a bare-metal system, the performance of pass-through GPUs degrades 9.0% and 21.5% under a single VM and 8-VMs respectively. We analyze the workflow of Windows display driver model and VMEXIT events distribution and identify four factors (i.e. HLT instruction and idle domain, external interrupt delivery, IOMMU, and memory subsystem) that contribute to the performance degradation. Our evaluation results show that: (1) the VM-VMM context switch caused by a HLT instruction and wake-up interrupt injection of an idle domain result in 66. 7% idle time for a single pass-through GPU; (2) the external interrupt delivery and tasklet processing cause additional overheads. When 8 VMs are consolidated, the interrupt delivery processing time and interrupt frequency rise 30.7% and 127.3%, respectively; (3) the existing IOMMU design scales well with pass-through GPUs; and (4) interactions of domain guest's software stacks impact the hardware prefetching mechanism so that it fails to compensate the rapidly growing LLC miss rate when more pass-through GPU VMs are added. To the best of our knowledge, this is the first work that characterizes pass-through GPU virtualization overheads an

international symposium for Design and Technology of Electronics Packages (SIITME)

作者： T.C. Bălan D.N. Robu F. Sandu Department of Electronics and Computers “Transilvania” University of Brasov Romania

For the university computer labs there is a real challenge for the fixed infrastructure to keep the pace with the increased demand for computational resources. The complexity of the computer architecture is given by the high number of complex software tools, the virtual machines, the different operating systems and the great range of different classes with laboratory lessons, especially for computer engineering students. One solution would be the use of private university-owned Cloud but not all universities can afford a modern thin-client solution. This paper presents an intermediate non-expensive step towards working with distributed resources for computer laboratories, a remote boot system, using Clonezilla and Diskless Remote Boot in Linux - DRBL, methods implemented and tested in a demo system.

Pacific Rim international symposium on Dependable computing

作者： Mikio Hashimoto Naoko Yamada Jun Kanai Computer Architecture & Security Systems Laboratory Corporate Research & Development Center Toshiba Saiwai-ku Kawasaki Japan

In view of the introduction of computer technologies into social infrastructure, computer security is rapidly emerging as a major real-world problem. Since control devices are left in physically insecure fields, the risk of physical attack is a greater concern than in the case of data center systems. In addition, non-volatile main memory technology may extend the threat because an attacker can easily manipulate and retrieve data stored in the memory. Much research has been done with a view to realizing secure processors with integrity tree verification, but no secure processor product with MMU capability has been commercialized so far. In this paper, TREBIVE, a TREe-Based Integrity Verification Environment, is proposed. It offers VMM-based memory integrity and confidentiality protection for existing COTS processors. A prototype VMM is constructed using ARM Cortex-A15 processors and quantitative analysis is performed using the Linux environment. The result shows a considerable amount of overhead, which is a concern. However, the results of experiments on SQLite queries support the view that the proposed method offers quicker response than whole DB image verification on existing systems. A target system model to mitigate the overhead is also proposed, in order to support robust disconnected operation of field devices.

international symposium on computing and Networking (CANDAR)

The Propositional Satisfiability Problem (SAT) is one of the most fundamental NP-complete problems. In this paper, a high-performance and heterogeneous SAT solving algorithm is presented. This algorithm, called CUDA-WSat-PcL, uses Pseudo-conflict Learning with a WalkSAT algorithm and exploits a massively parallel architecture on a Graphics Processing Unit (GPU) together with a conventional CPU on NVIDIA's Compute Unified Device architecture (CUDA) platform. Our experimental results reveal that the heterogeneous and parallelized implementation finds the results up to 25 times faster than our sequential implementation. Additionally, our profiling results show that the improvements depend solely on instance size.

The ever growing complexity and scale of parallel architectures imposes to rewrite classical monolithic HPC scientific applications and libraries as their portability and performance optimization only comes at a prohibitive cost. There is thus a recent and general trend in using instead a modular approach where numerical algorithms are written at a high level independently of the hardware architecture as Directed Acyclic Graphs (DAG) of tasks. A task-based runtime system then dynamically schedules the resulting DAG on the different computing resources, automatically taking care of data movement and taking into account the possible speed heterogeneity and variability. Evaluating the performance of such complex and dynamic systems is extremely challenging especially for irregular codes. In this article, we explain how we crafted a faithful simulation, both in terms of performance and memory usage, of the behavior of qr_mumps, a fully-featured sparse linear algebra library, on multi-core architectures. In our approach, the target high-end machines are calibrated only once to derive sound performance models. These models can then be used at will to quickly predict and study in a reproducible way the performance of such irregular and resource-demanding applications using solely a commodity laptop.

The Physical Unclonable Function (PUF) has broad application prospects in the field of hardware security. The arbiter PUF is a typical kind of strong PUF. However, due to its deterministic logic, attackers can use modeling techniques to break it in short time. Therefore, this paper proposes an Obfuscation logic based PUF (OPUF) design. A Boolean obfuscation module is proposed to obfuscate the logic which is employed to select the path segments in the arbiter PUF. In this way, the nondeterminacy of PUF is improved, and the computation complexities of modeling attacks are significantly increased, making the OPUF much safer against modeling attack. Both the theoretical analysis and the experimental results show the proposed OPUF design has good stability and randomness.

Border effect in communication network area is one of the most important problems to quantify accurately the performance/dependability of wireless ad hoc networks (WAHNs), because the assumption on uniformity of network node density is often unrealistic to describe the actual communication area. This problem appears in modeling the node behavior of WAHNs and in quantification of their network survivability. In this paper we focus on the border effects, and reformulate the network survivability models based on a semi-Markov process, where two kinds of communication network areas are considered, square area and circular area. Based on some geometric ideas, we improve the quantitative network survivability measures for three stochastic models taking account of the border effects. In numerical examples, we compare our new models with the existing ones without border effects in both steady-state and transient network survivability analyses. We show through a simulation study that the border effects are significant factors in quantifying network survivability.

Networks-on-Chip (NoC) have been established as the de facto standard for on-chip communication in multi-/many-core systems, due to their innate scalability properties pertaining to performance and physical implementation. Spanning the entire chip, the NoC suffers from both inter-die and intra-die variations. In addition to static variability, the NoC is also afflected by dynamic variations, such as fast VDD droops, temperature, and aging effects. Such variations cause unpredictable behavior in the timing characteristics of the NoC components, which need significant timing margins to ensure always-correct operation. Consequently, the potential for high-frequency operation is impeded. In this paper, we propose a timing-error-resilient mechanism called TRNoC, which allows the NoC to operate at higher frequencies, at the expense of sporadically experiencing run-time timing errors, which are handled by an error recovery strategy. TRNoC includes a lightweight timing-error detection mechanism, together with a distributed error recovery mechanism, which allow for lossless operation, while leaving the error-free parts of the network unaffected. Hardware implementation results demonstrate the efficiency of TRNoC and its potential as a scalable timing-error-resilient NoC architecture.

Rain streak in an image can degrade the human vision, as well as the image's quality. However, the rain removal of a single image is a challenging problem, because the rain is moving fast and may become torrential. In this paper, a single image rain removal process based on the non-negative matrix factorization is proposed. In the proposed method, the rain image is decomposed into a low-frequency part and a high-frequency part by a Gaussian filter. Therefore, the rain component, which is usually in the middle frequency, could be discarded in high and low frequency domains. In this paper, the non-negative matrix factorization (NMF) method is applied to deal with the rain streak in the low frequency;while in the high frequency part, the concept of Canny edge detection and block copy strategy are utilized separately to remove the rain hidden in high frequency and improve the image quality. By comparing with the state-of-the-art approaches, our proposed method does not need the extra image database to train the desirable dictionary, but still reaches similar results.

Many organizations today still manage mid or large in-house data centers that require very expensive maintenance efforts, including fault detection. Common monitoring frameworks used to quickly detect faults are complex to deploy/maintain, expensive, and intrusive as they require the installation of probes on monitored hw/sw to collect raw data. Such intrusiveness can be problematic as it imposes installation/management overhead and may interfere with security/privacy policies. In this paper we introduce NIRVANA, a novel monitoring system for fault detection that works at rack-level and is (i) non-intrusive, i.e., it does not require the installation of software probes on the hosts to be monitored and (ii) black-box, i.e., agnostic with respect to monitored applications. At the core of our solution lies the observation that aggregated features that can be monitored at rack-level in a non-intrusive and black-box way, show predictable behaviors while the system works in both fault-free and faulty states, it is therefore possible to detect and identify faults by monitoring and analyzing any perturbations to these behaviors. An extensive experimental evaluation shows that non-intrusiveness does not significantly hamper the fault detection capabilities of the monitoring system, thus validating our approach.
