[Abstract]
Since the very beginning of hardware development, computer processors were invented with ever-increasing clock frequencies and sophisticated in-build optimization strategies. Due to physical limitations, this 'free lunch' of speedup has come to an end. The following article gives a summary and bibliography for recent trends and challenges in CMP architectures. It discusses how 40 years of parallel computing research need to be considered in the upcoming multi-core era. We argue that future research must be driven from two sides - a better expression of hardware structures, and a domain-specific understanding of software parallelism.

[Abstract]
Cluster and Grid environments mostly require the use of product-specific Application Programming Interface (APIs) to submit, control and monitor computational jobs. The Open Grid Forum standardisation body therefore has developed several specifications to fill the gap and enable developers to code to few standardised APIs. This paper discusses the details of one of these specifications, the Distributed Resource Management Application API. We compare the basic concepts of the finalised API to other specifications from the same area and explain issues and findings uncovered during the standardisation process.

[Abstract]
The advent of homogeneous many-core processors has been widely noticed as a major shift in the architecture of commodity computer systems. It has influenced the design of operating systems and programming models and gives a boost to high-level parallelization libraries. Future commodity systems will combine homogeneous many-core processors with graphical processing units and other special purpose accelerators to a new class of architecture called hybrid system. These systems provide improved hardware support for specialized computational tasks of different applications. In contrast to the programming for homogeneous architectures with existing tools, programming for such hybrid architectures is still in its infancy. Today, the software development for such systems explicitly has to address vendor-specific and version-specific characteristics of the particular devices. Due to this, refactoring of existing code becomes a tedious and error-prone task. We present our approach for automatically transforming high-level parallel code written in .NET to parallel code suitable for direct execution on hybrid systems. Our approach relies on the transformation of .NET byte code to an accelerator-aware version, which makes the concept applicable to all .NET-supported programming languages. Hybrid system hardware is targeted by the generation of accelerator-neutral intermediate code, which makes our approach applicable for a wider class of accelerator types. We show the feasibility of our solution with a workload that consists of well-known and widely accepted compute-intense algorithmic problems.

[Abstract]
With the ongoing internationalization of virtuallaboratories, the integration aspect becomes moreimportant. The meanwhile commonly accepted âglueâ forsuch legacy systems are service oriented architectures, basedon standardized and accepted Web service standards.We present our concept of the âexperiment as a serviceâ,where the idea of service-based architectures is applied tovirtual remote laboratories. In our laboratory middleware,experiments are represented as stateful serviceimplementations and jobs as logical service instances ofthese implementations. We discuss performance, reliability,security and monitoring issues in this approach, and showhow the resulting infrastructure - the Distributed ControlLab - is applied in the European VetTrend project.

[Abstract]
Modern virtualization environments allow the live migration of running systems for load balancing and failover purposes in case of failing hosts. The overall duration of such migration and the short downtime during this process are essential properties when implementing service availability agreements. However, both metrics are currently only determinable through direct experimentation. For this reason, we present a new model for estimating the worst-case values of migration time and downtime in live migration. The prediction is based on a small set of input parameters characterizing the application load and the behavior of the host. We performed a large set of experimental evaluations for the model with three different virtualization products. The results show that total migration time as well as downtime are mainly influenced by the memory utilization pattern inside the virtualized system. The experiments also confirm that the proposed model can predict worst-case live migration performance with high accuracy, rendering the model a useful tool for implementing proactive virtual machine migration.

[Abstract]
Software-implemented fault injection (SWIFI) is an established method to emulate hardware faults in computer systems. Existing approaches either extend the operating system by special drivers, modify the runtime environment, or change the application under test.
The FutureSOC project on software-implemented fault injection investigates new ideas for adding fault triggering and simulation as standard dependability assessment tool in modern server environments. The following report summarizes the results of the initial analysis phase.

[Abstract]
The introduction of service-orientation leads to significant improvements regarding flexibility in the choice of business partners and IT-systems. This requires an increased adaptability of enterprise software landscapes as the environment is more dynamic than the ones in traditional approaches. In this paper we present different types of adaptation scenarios for service compositions and their implementation in a service provision platform. Based on experiences from the Adaptive Services Grid (ASG) project, we show how dynamic adaptation strategies are able to support an automated selection, composition and binding of services during run-time.

[Abstract]
While tools for service-oriented architectures promise a seamless combination of stateless basic services to new applications, reality looks different. Real-world services are wrapping stateful behavior using application-specific concepts, the monitoring is only available through vendorspecific interfaces, and service installations are bound to particular execution hosts. We present the ASG Services Infrastructure (SI) architecture as our practical solution to these real-world service integration issues. Our framework is based on established Web service standards and supports the dynamic hosting and monitoring of heterogeneous and stateful service implementations.

[Abstract]
Most of todayâs distributed computing systems in the field do not support the migration of execution entities among computing nodes during runtime. The relatively static association between units of processing and computing nodes makes it difficult to implement fault-tolerant behavior or load-balancing schemes. The concept of code migration may provide a solution to the problems mentioned above. It can be defined as the movement of process, object or component instances from one computing node to another during system runtime in a distributed environment. Within our paper we describe the integration of a migration facility with the help of Aspect-Oriented Programming (AOP) into the.NET framework. AOP is interesting as it addresses non-functional system properties on the middleware level, without the need to manipulate lower system layers like the operating system itself. We have implemented two proof-of-concept applications, namely a migrating web server as well as a migrating file version checker application. The paper contains an experimental evaluation of the performance impact of object migration in context of those two applications.

[Abstract]
A recent trend in the design of commodity processors is the combination of multiple independent execution units on one
chip. With the resulting increase of complexity and transistor count, it becomes more and more likely that a single execution unit on
a processor gets faulty. In order to tackle this situation, we propose an architecture for dependable process management in chip-
multiprocessing machines. In our approach, execution units sur veil each other to anticipate future hardware failures. The prediction
relies on the analysis of processor hardware performance counters by a statistical rank-sum test. Initial experiments with the Intel Core
processor platform proved the feasibility of the approach, but also showed the need for fur ther investigation due to a high prediction
quality variation in most of the cases.

[Abstract]
Remote and virtual laboratories are commonly used in electronic engineering and computer science to provide hands-on experience for students. Web services have lately emerged as a standardized interfaces to remote laboratory experiments and simulators. One drawback of direct Web service interfaces to experiments is that the connected hardware could be damaged due to missed deadlines of the remotely executed control applications.
Within this paper, we suggest an architecture for predictable and interactive control of remote laboratory experiments accessed over Web service protocols. We present this concept as an extension of our existing Distributed Control Lab infrastructure. Using our architecture, students can conduct complex control experiments on physical experiments remotely without harming hardware installations.

[Abstract]
Physical memory faults are one of the accepted reliability threats for modern processor technology. Even though error correction for memory hardware can deal with this class of fault, many processor designs such as X86 do not invest semiconductor complexity and space to deal with multi-bit faults in caches and registers. In this paper, we analyze how the right choice of compiler options can act as software-based error prevention strategy for register file faults. This investigation is based on a classification scheme for GCC compiler options and a new fault injection environment for automated experiments. The study proves the the initial hypothesis that reliability improvements mainly depend on the algorithmic structure of the application under test. A small number of compiler options have proven to be a feasible application-independent error mitigation strategy.

[Abstract]
The Distributed Control Lab (DCL)[10] provides an open infrastructure for conducting robotics and control experiments from the Internet. It is based on web service technologies and offers a wide range of frontend applications. Within the DCL environment we focus on safety mechanisms in order to prevent malicious code from damaging experimental equipment. This includes source code analysis, runtime observation and the dynamic replacement of faulty control algorithms. Within the paper we present an overview of our architecture and explain the implemented frontends in detail. We introduce the installed experiments and report our experiences from operation in the last years. In addition we will describe our latest integration of grid computing technologies, which allows the outsourcing of computing-intensive simulation tasks.

[Abstract]
This paper presents our idea of FuzzTrees for reliability modeling. The approach extends classical fault tree analysis by two additional concepts: Fuzzy event probabilities and the consideration of architectural variation points. FuzzTrees allow the incremental analysis of the cost-reliability tradeoff in conïŹgurable systems.

[Abstract]
Proactive failover is a resiliency strategy that replaces classical reactive recovery by a combination of failure prediction and preventive failover. The approach can be applied to different hardware and software layers that exist in modern evolving systems â but each layer has its own costs and failover capabilities.
This paper investigates the applicability of virtual machine live migration for proactive failover, based on a generic strategy for choosing a proactive failover system level. The experimental performance analysis shows that virtual machine live migration has product-specific performance behavior with product-independent upper bounds on the total migration time. One major influencing factor is the dirty page generation rate inside of the virtual machine.

[Abstract]
Software-implemented fault injection is an established method to emulate hardware faults in computer systems. Existing approaches typically extend the operating system by special drivers or change the application under test. We propose a novel approach where fault injection capabilities are added to the computer firmware. This approach can work without any modification to operating system and / or applications, and can support a larger variety of fault locations. We discuss four different strategies in X86/X64 and Itanium systems. Our analysis shows that such an approach can increase portability, the non-intrusiveness of the injector implementation, and the number of supported fault locations. Firmware-level fault injection paves the way for new research directions, such as virtual machine monitor fault injection or the investigation of certified operating systems.

[Abstract]
Virtual machine environments like VMware, XEN, KVM, and Hyper-V support live migration of guest operating systems, which is used in data centers to provide uninterrupted service during maintenance or to move computation away from failure-prone hosts. The duration of migration, as well as the virtual machine downtime during this process are essential when assessing if service availability agreements might be violated.
We present the result of an experimental study that analyzed virtual machine live migration downtime and duration. We show that total migration time as well as downtime are dominated by specific memory utilization patterns inside the virtualized guest. We experienced that downtime involved by live migration can vary by a factor of more than 23, which can have significant impact on service availability

[Abstract]
Next generation technologies such as multi-core
processors and large memory modules will result in
tremendously increased computing power. However,
this comes at a price: Due to the growing number of
transistors and increased complexity, overall system
reliability of future server systems is about to suffer
significantly.
The HPI FutureSOC Lab project âTowards an Archi-
tectural Pattern for Pro-Active Virtual Machine Mi-
grationâ 1 investigates an architectural blueprint for
managing system dependability in a pro-active fash-
ion. The approach is based on virtual machine live
migration technologies and new failure prediction
approaches.
Within this article, we present initial experimental
results of the project, with a focus on virtual machine
live migration capabilities.

[Abstract]
Next generation processor and memory technologies will provide tremendously increasing computing and memory capacities for application scaling. However, this comes at a price: Due to the growing number of transistors and shrinking structural sizes, overall system reliability of future server systems is about to suffer significantly. This makes reactive fault tolerance schemes less appropriate for server applications under reliability and timeliness constraints.
We propose an architectural blueprint for managing server system dependability in a pro-active fashion, in order to keep service-level promises for response times and availability even with increasing hardware failure rates. We introduce the concept of anticipatory virtual machine migration that proactively moves computation away from faulty or suspicious machines. The migration decision is based on health indicators at various system levels that are combined into a global probabilistic reliability measure. Based on this measure, live migration techniques can be triggered in order to move computation to healthy machines even before a failure brings the system down.
