SUMMARY:SystemCoDesigner: Automatic Design Space Exploration and Rapid Prototyping from Behavioral Models
DESCRIPTION:SystemCoDesigner: Automatic Design Space Exploration and Rapid Prototyping from Behavioral Models\n\n\n\n\nSpeaker\n\n\nDr. Christian Haubelt\nUniversity of Erlangen-Nuremberg\, Germany\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nEngineering Tower\, Room 331\, University of California\, Irvine\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nJune 13 \, 2008\nTalk begins 11:00am\nRefreshments at 10:30am\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\n80% of all design decisions are made in the first 20% of the design time. Thus\, a substantiated knowledge about possible solutions is mandatory in early design phases in order to design high quality products. SystemCoDesigner is a software tool for automatic design space exploration at the electronic system level and for platform-based prototyping of hardware/software systems. By exploring the design space\, a designer becomes more confident in decisions to be done. Starting from a behavioral SystemC description different solutions are generated automatically by using software synthesis techniques and Forte Design Systems’ Cynthesizer for behavioral hardware synthesis. In order to allow such a degree of automation\, SystemCoDesigner requires the behavioral SystemC model to be representable in a well-defined Model of Computation\, called FunState. As a case study\, a model of a Motion-JPEG decoder was automatically optimized and implemented using SystemCoDesigner. Several synthesized SoC variants based on this model show different tradeoffs between required hardware costs and achieved system throughput\, ranging from software only solutions up to pure hardware implementations which reach real-time performance for QCIF streams on a 50MHz FPGA. In this talk\, the SystemCoDesigner overall design flow\, the FunState Model of Computation\, and some automatic transformation are presented using the Motion-JPEG case study.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n\n\nChristian Haubelt received his diploma degree in Electrical Engineering from the University of Paderborn\, Germany\, in 2001. He received his Ph.D. in Computer Science from the University of Erlangen-Nuremberg\, Germany\, in 2005. Since 2004\, he is head of the System-Level Design Automation Group at the Chair of Hardware/Software Co-Design\, University of Erlangen-Nuremberg\, Germany. Dr. Haubelt’s research interests include electronic system level design\, system level design automation\, and multi-objective optimization.\n\n\n\n\n\n\n\n\n\n\nWeb Site\n\n\nhttp://www12.informatik.uni-erlangen.de/people/haubelt/

SUMMARY:Nonlinear Symbolic Program Analysis for Increased Parallelization
DESCRIPTION:Nonlinear Symbolic Program Analysis for Increased Parallelization\n\n\n\n\nSpeaker\n\n\nProfessor Kleanthis Psarris \nDepartment of Computer Science\nThe University of Texas at San Antonio\, TX\n\n\n\n\n\n\n\n\n\n\nCECS Host\n\n\nProfessor Alex Nicolau\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nMcDonnell Douglas Auditorium\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nMarch 9\, 2009\nRefreshments at 2:30 pm\, Lecture begins at 3:00pm\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nHigh end parallel and multi-core processors rely on compilers to perform the necessary optimizations and exploit concurrency in order to achieve higher performance. However\, source code for high performance computers is extremely complex to analyze and optimize. In particular\, program analysis techniques often do not take into account complex expressions during the data dependence analysis phase. Most data dependence tests are only able to analyze linear expressions\, even though non-linear expressions occur very often in practice. Therefore\, considerable amounts of potential parallelism remain unexploited. In this talk we propose new data dependence analysis techniques to handle such complex instances of the dependence problem and increase program parallelization. Our method is based on a set of polynomial time techniques that can prove or disprove dependences in source codes with non-linear and symbolic expressions\, complex loop bounds\, arrays with coupled subscripts\, and if-statement constraints. In addition our algorithm can produce accurate and complete direction vector information\, enabling the compiler to apply further transformations. To validate our method we performed an experimental evaluation and comparison against the I-Test\, the Omega test and the Range test in the Perfect and SPEC benchmarks. The experimental results indicate that our dependence analysis tool is accurate\, efficient and more effective in program parallelization than the other dependence tests. The improved parallelization results into higher speedups and better program execution performance in several benchmarks.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n  \n\nKleanthis Psarris is Professor and Chair of the Department of Computer Science at the University of Texas at San Antonio.

Fine grain power gating is a promising way to reduce leakage power. However\, applying fine grain power gating at very close intervals suffers from energy overhead caused by power gating itself.

SUMMARY:Compiler-enabled Power-efficient Register File Protection
DESCRIPTION:Compiler-enabled Power-efficient Register File Protection\n\n\n\n\nSpeaker\n\n\nDr. Jongeun Lee\nEECS\, Ulsan National Institute of Science and Technology\,Korea\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nDonald Bren Hall (DBH) 3011\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nJuly 22\, 2009\nRefreshments at 10:30 am\, Lecture begins at 11:00am\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nRegister file (RF) is extremely vulnerable to soft errors\, and traditional redundancy based schemes to protect the RF are prohibitive not only because RF is often in the timing critical path of the processor\, but also since it is one of the hottest blocks on the chip\, and therefore adding any extra circuitry to it is not desirable. Software approaches would be ideal in this case\, but previous approaches that are based on program duplication have very significant runtime overheads\, and others based on instruction scheduling are only moderately effective due to local scope.  \nThis talk will be about how compiler alone and in conjunction with microarchitecture can power-efficiently protect the RF. What we have observed is that a significant portion of the RF vulnerability is contributed by long lifetime variables. Protecting only these can result in power-efficient RF protection. Thus the task of the compiler is to identify program variables that have long lifetimes and protect them. Our experiments demonstrate pure compiler techniques can reduce the vulnerability of the RF by 33-37% on average and up to 66%\, with a small (2%) runtime overhead. As compared to hardware protection mechanisms\, compiler analysis can achieve the same level of protection but at up to 75% lesser RF energy consumption.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n\n \nJongeun Lee received a BS and an MS in Electrical Engineering and a PhD in Electrical Engineering and Computer Science all from Seoul National University. Previously he was with Samsung SoC R&D Center in Korea\, and is currently a postdoctoral associate at Arizona State University\, working with Dr. Aviral Shrivastava. He is joining Ulsan National Institute of Science and Technology\, Korea\, as an Assistant Professor of EECS. His research interests include configurable/reconfigurable processor architecture design\, compilation for energy and reliability\, and compilation for multicore processors and GPUs.

SUMMARY:Power Efficient and Fault Tolerant Circuits and Systems Using Commodity FPGA
DESCRIPTION:Power Efficient and Fault Tolerant Circuits and Systems Using Commodity FPGA\n\n\n\n\nSpeaker\n\n\nProf. Lei He\nElectrical Engineering Department\,\nUCLA\n\n\n\n\n\n\n\n\n\n\nCECS Host\n\n\nProfessor Eli Bozorgzadeh\n\n\n\n\n\n\n\n\n\n\nLocation\n\n\nEngineering Hall (EH) 2430\n\n\n\n\n\n\n\n\n\n\nDate & Time\n\n\nOctober 9\, 2009\nRefreshments at 10:30am; Lecture begins at 11:00am\n\n\n\n\n\n\n\n\n\n\nAbstract\n\n\nAs devices become smaller\, circuits and systems are more vulnerable to soft errors caused by radiation and other environmental upsets. Fault tolerance measured by mean time to failure (MTTF) is desired\, especially if no extra area\, power and delay and little change of the existing design flow are introduced. Using FPGA and internet router as a testbed\, this talk first presents fault tolerance techniques applying (1) logic don’t care and path re-convergence (ROSE) and (2) in-place logic re-writing (IPR). Both increase MTTF by 2X with little or no overhead. Particularly\, IPR does not change circuit placement and routing\, and can be readily used with the existing industrial design flow. It also leads to a self evolution method to enhance fault tolerance for FPGA based circuits and systems. Finally\, I will briefly discuss my ongoing research on cyber-physical systems involving renewal energy storage and environment/water monitoring.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\nDr. Lei He is an associate professor at electrical engineering department\, UCLA\, and was a faculty member at University of Wisconsin\, Madison between 1999 and 2001.

We derived optimal power management strategies for stationary workloads that have been implemented both in HW and SW. Run-time adaptation can be done via an online learning algorithm that selects among a set of policies. We generalized the algorithm to include thermal management since we found that minimizing the power consumption does not necessarily reduce the overall energy costs. To reduce the performance costs typically associated with state of the art thermal management techniques\, we also developed a new set of proactive management policies. The experimental results using real datacenter workloads on an actual multicore system show that our proactive technique is able to dramatically reduce the adverse effects of temperature by over 60%. Most recently we have shown that symbiotic scheduling of workloads in virtualized environments can lead to average 15% energy savings with 20% performance benefit in high utilization scenarios.We will also present some of the recent work that address the energy savings in battery powered systems\, as demonstrated in a new kind of “citizen infrastructure”\, an end-to-end health and environmental information system with near real-time data streams and feedback loops from the system to the sensing\, processing\, and actuation infrastructure. We have developed adaptive algorithms to tradeoff accuracy of computation versus the available energy for such systems\, while taking into account the energy harvesting capabilities.\n\n\n\n\n\n\n\n\n\n\nBiography\n\n\n\n \nTajana Simunic Rosing is currently an Assistant Professor in Computer Science Department at UCSD\, a director of System Energy Efficiency Lab at UCSD and a head of the Energy efficient datacenter thrust as a part of the MuSyC center.
