“…1 up left) in the software, but this new environment will on the other hand enable a higher level of error mitigation. At the design time, we are able to detect which points are optimal in terms of energy vs execution time (Pareto Points [9]). The multi-threaded solution has not to be run on the HPC cluster at the best-effort.…”

“…With OpenMP pragmas, we can decide the resources used to compute the HPC application. There are diverse Pareto points [9] from a sequential execution to an execution with all resources available (16 cores and the accelerators). In some cases, resources do not have to be available due to temporal or permanent hardware errors (greyed out in Fig.…”

Part 5: Industrial Management and Other ApplicationsInternational audienceIn the future, the silicon technology will continue to reduce following the Moore’s law. Device variability is going to increase due to a loss in controllability during silicon chip fabrication. Then, the mean time between failures is also going to decrease. The current methodologies based on error detection and thread re-execution (roll back) can not be enough, when the number of errors increases and arrives to a specific threshold. This dynamic scenario can be very negative if we are executing programs in HPC systems where a correct, accurate and time constrained solution is expected. The objective of this paper is to describe and analyse the needs and constraints of different applications studied in disaster management processes. These applications fall mainly in the domains of the High Performance Computing (HPC). Even if this domain can have differences in terms of computation needs, system form factor and power consumption, it nevertheless shares some commonalities

“…The framework design, which exposes different plug in interfaces, provides support for pluggable policies for both resource scheduling and the management of applications coordination and reconfiguration. Applications integrated with this framework get a suitable instrumentation to support Design-Space-Exploration (DSE) techniques, which could be used to profile application behaviours to either optimize them at design time or support the identification of optimal QoS [6] requirements goals as well as their run-time monitoring.…”

In this paper is proposed a HPC system running with an RTOS that is aware and monitors the health of the platform. On the system, an application for disaster management is running. The application can be executed with different QoS depending on the situation. We defined two main situations normal execution when there is no possibility of disaster. And, a scenario where the possibilities for a disaster is very high. Then, the resource allocation for improving the precision and human decision has to be taken into account. The paper shows that at design time, it is possible to describe the different phases for developing a run-time application that is aware of the power consumption and tries to minimized when the situation is not in the scenario of criticality. Since, power consumption is a critical consideration in high performance computing systems and it is becoming the limiting factor to build and operate Petascale and Exascale systems.

“…This modularization also allows for automated design flows that can optimally select hardware resources from a multi-component architecture for data-dominated MSP algorithm flows [17], [18], [70]. Finally, the importance of this modularization of algorithmic components into high-performance computational kernels of software libraries is demonstrated by the recent definition of the reconfigurable video coding specification [71] within MPEG video coding standards.…”

Error Tolerant Multimedia Stream Processing: There's Plenty of Room at the Top (of the System Stack)

Abstract-There is a growing realization that the expected fault rates and energy dissipation stemming from increases in CMOS integration will lead to the abandonment of traditional system reliability in favor of approaches that offer reliability to hardware-induced errors across the application, runtime support, architecture, device and integrated-circuit (IC) layers. Commercial stakeholders of multimedia stream processing (MSP) applications, such as information retrieval, stream mining systems, and high-throughput image and video processing systems already feel the strain of inadequate system-level scaling and robustness under the always-increasing user demand. While such applications can tolerate certain imprecision in their results, today's MSP systems do not support a systematic way to exploit this aspect for cross-layer system resilience. However, research is currently emerging that attempts to utilize the error-tolerant nature of MSP applications for this purpose. This is achieved by modifications to all layers of the system stack, from algorithms and software to the architecture and device layer, and even the IC digital logic synthesis itself. Unlike conventional processing that aims for worst-case performance and accuracy guarantees, error-tolerant MSP attempts to provide guarantees for the expected performance and accuracy. In this paper we review recent advances in this field from an MSP and a system (layer-by-layer) perspective, and attempt to foresee some of the components of future cross-layer error-tolerant system design that may influence the multimedia and the general computing landscape within the next ten years.
