H-Container: Enabling Heterogeneous-ISA Container Migration in Edge Computing
No full textEdge computing is a recent computing paradigm that brings cloud services closer to the client. Among other features, edge computing offers extremely low client/server latencies. To consistently provide such low latencies, services should run on edge nodes that are physically as close as possible to their clients. Thus, when the physical location of a client changes, a service should migrate between edge nodes to maintain proximity. Differently from cloud nodes, edge nodes integrate CPUs of different Instruction Set Architectures (ISAs), hence a program natively compiled for a given ISA cannot migrate to a server equipped with a CPU of a different ISA. This hinders migration to the closest node. We introduce H-Container, a system which migrates natively-compiled containerized applications across compute nodes featuring CPUs of different ISAs. H-Container advances over existing heterogeneous-ISA migration systems by being a) highly compatible – no user’s source-code nor compiler toolchain modifications are needed; b) easily deployable – fully implemented in user space, thus without any OS or hypervisor dependency, and c) largely Linux compliant – it can migrate most Linux software, including server applications and dynamically linked binaries. H-Container targets Linux and its already-compiled executables, adopts LLVM, extends CRIU, and integrates with Docker. Experiments demonstrate that H-Container adds no overheads during program execution, while 10 − 100ms are added during migration. Furthermore, we show the benefits of H-Container in real-world scenarios, demonstrating for example up to (94% ) increase in Redis throughput when client/server proximity is maintained through heterogeneous container migration
Ubiquitous computing platform via hardware assisted ISA virtualization
No full textWe propose a ubiquitous computing platform that supports multiple industrial instruction set architecture (ISA) standards via hardware assisted ISA virtualization. The proposed architecture features the following innovations: 1) It employs an efficient hardware assisted dynamic binary translation approach, 2) It implements a native semantically rich instruction set architecture that achieves when translating user level code one-to-one mappings for RISC ISAs such as ARM and a minimal one-to-multiple mappings for CISC ISAs such as Intel X86, and 3) It tackles, without compromising performance or energy efficiency and without requiring recompilation of software or rewriting of compilers, the issue of software portability across different ISA platforms through unhosted hardware assisted ISA virtualization. After introducing a metric to compare the semantic difference between an emulated virtual ISA and the native platform ISA, we present performance results as well as measurements of the effectiveness of our proposed platform when running ARM and X86 binaries. © 2013 IEEE

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Constrained H<inf>2</inf> approximation of multiple input-output delay systems using genetic algorithm
No full textThe paper presents a constrained H2 approximation method for multiple input-output delay systems by using a genetic algorithm. The H2 error between the original and the approximate models is minimized subject to constraints on the H∞ error between them and the matching of their steady-state under step inputs. In particular, the H2 error is used as the objective (fitness) function for minimization with the best parameters of the approximate model obtained by repeating the genetic operations on the population incorporated a parameter search space expansion scheme. The effectiveness of the proposed method is demonstrated by numerical examples. It is shown that the approximate models obtained by this approach have better approximation performance in both the H2 and H∞ norms, as well as the steady-state response, than those obtained by a previous gradient-based minimization approach. © 2007 ISA
