With the emergence of new issues like Electro-migration these problems are getting more crucial. Age monitoring methods can be used to predict and deal with the aging problem. Selecting appropriate locations for placement of aging monitors is an important issue. In this work we propose a procedure for selection of appropriate internal nodes that expose smaller overheads to the circuit, using correlation between nodes and the shareability amongst them. To select internal nodes, we first prune some nodes based on some attributes and thus provide a near-optimal solution that can effectively get a number of internal nodes and consider the effects of electro-migration as well. We have applied our proposed scheme to several processors and ITC benchmarks and have looked at its effectiveness for these circuits."}],"status":"public","date_updated":"2023-08-02T11:36:15Z","publisher":"IEEE","date_created":"2022-01-19T13:35:37Z","author":[{"first_name":"Somayeh","full_name":"Sadeghi-Kohan, Somayeh","id":"78614","orcid":"https://orcid.org/0000-0001-7246-0610","last_name":"Sadeghi-Kohan"},{"first_name":"Arash","last_name":"Vafaei","full_name":"Vafaei, Arash"},{"first_name":"Zainalabedin","full_name":"Navabi, Zainalabedin","last_name":"Navabi"}],"title":"Near-Optimal Node Selection Procedure for Aging Monitor Placement","doi":"10.1109/iolts.2018.8474120","publication_status":"published","year":"2018","citation":{"apa":"Sadeghi-Kohan, S., Vafaei, A., &#38; Navabi, Z.

These have been shown to be connected to catastrophe theory via generating functions and ordinary and reversal phase space symmetries have been considered. Here we present a convenient, coordinate free framework to analyse separated Lagrangian boundary value problems which include classical Dirichlet, Neumann and Robin boundary value problems. The framework is then used to prove the existence of obstructions arising from conformal symplectic symmetries on the bifurcation behaviour of solutions to Hamiltonian boundary value problems. Under non-degeneracy conditions, a group action by conformal symplectic symmetries has the effect that the flow map cannot degenerate in a direction which is tangential to the action. This imposes restrictions on which singularities can occur in boundary value problems. Our results generalise classical results about conjugate loci on Riemannian manifolds to a large class of Hamiltonian boundary value problems with, for example, scaling symmetries.

In computational sciences, often more advanced methods are employed that promise better stability, convergence, locality and scaling. Unstructured meshes are shown to be more effective and more accurate, compared to regular grids, in representing computation domains of various shapes. Using unstructured meshes, the discontinuous Galerkin method preserves the ability to perform explicit local update operations for simulations in the time domain. In this work, we investigate FPGAs as target platform for an implementation of the nodal discontinuous Galerkin method to find time-domain solutions of Maxwell's equations in an unstructured mesh. When maximizing data reuse and fitting constant coefficients into suitably partitioned on-chip memory, high computational intensity allows us to implement and feed wide data paths with hundreds of floating point operators. By decoupling off-chip memory accesses from the computations, high memory bandwidth can be sustained, even for the irregular access pattern required by parts of the application. Using the Intel/Altera OpenCL SDK for FPGAs, we present different implementation variants for different polynomial orders of the method. In different phases of the algorithm, either computational or bandwidth limits of the Arria 10 platform are almost reached, thus outperforming a highly multithreaded CPU implementation by around 2x."}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":269130,"access_level":"closed","file_id":"5282","file_name":"08457652.pdf","date_updated":"2018-11-02T14:45:05Z","date_created":"2018-11-02T14:45:05Z","creator":"ups"}],"publisher":"IEEE","date_created":"2018-03-22T10:48:01Z","title":"OpenCL-based FPGA Design to Accelerate the Nodal Discontinuous Galerkin Method for Unstructured Meshes","quality_controlled":"1","year":"2018","_id":"1588","project":[{"name":"HighPerMeshes","_id":"33","grant_number":"01|H16005A"},{"_id":"1","name":"SFB 901","grant_number":"160364472"},{"_id":"4","name":"SFB 901 - Project Area C"},{"_id":"14","name":"SFB 901 - Subproject C2","grant_number":"160364472"}],"department":[{"_id":"27"},{"_id":"518"},{"_id":"61"}],"user_id":"15278","file_date_updated":"2018-11-02T14:45:05Z","type":"conference","status":"public","date_updated":"2023-09-26T11:47:52Z","author":[{"last_name":"Kenter","full_name":"Kenter, Tobias","id":"3145","first_name":"Tobias"},{"first_name":"Gopinath","last_name":"Mahale","full_name":"Mahale, Gopinath"},{"first_name":"Samer","full_name":"Alhaddad, Samer","id":"42456","last_name":"Alhaddad"},{"first_name":"Yevgen","full_name":"Grynko, Yevgen","id":"26059","last_name":"Grynko"},{"full_name":"Schmitt, Christian","last_name":"Schmitt","first_name":"Christian"},{"last_name":"Afzal","full_name":"Afzal, Ayesha","first_name":"Ayesha"},{"last_name":"Hannig","full_name":"Hannig, Frank","first_name":"Frank"},{"first_name":"Jens","id":"158","full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner"},{"first_name":"Christian","last_name":"Plessl","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","id":"16153"}],"doi":"10.1109/FCCM.2018.00037","conference":{"name":"Proc.

Following the idea of Approximate Computing, we allow imprecision in the final result in order to utilize the sparsity of the input matrix and to allow massively parallel execution. For an n x n matrix, the proposed algorithm allows to distribute the calculations over n nodes with only little communication overhead. The result matrix exhibits the same sparsity pattern as the input matrix, allowing for efficient reuse of allocated data structures.\r\n\r\nWe evaluate the algorithm with respect to the error that it introduces into calculated results, as well as its performance and scalability. We demonstrate that the error is relatively limited for well-conditioned matrices and that results are still valuable for error-resilient applications like preconditioning even for ill-conditioned matrices. We discuss the execution time and scaling of the algorithm on a theoretical level and present a distributed implementation of the algorithm using MPI and OpenMP. We demonstrate the scalability of this implementation by running it on a high-performance compute cluster comprised of 1024 CPU cores, showing a speedup of 665x compared to single-threaded execution.","lang":"eng"}],"external_id":{"arxiv":["1710.10899"]},"language":[{"iso":"eng"}],"keyword":["approximate computing","linear algebra","matrix inversion","matrix p-th roots","numeric algorithm","parallel computing"]},{"citation":{"bibtex":"@inproceedings{Riebler_Vaz_Kenter_Plessl_2018, title={Automated Code Acceleration Targeting Heterogeneous OpenCL Devices}, DOI={<a href=\"https://doi.org/10.1145/3178487.3178534\">10.1145/3178487.3178534</a>}, booktitle={Proc.

When doing such activities using large, real datasets, technology becomes and essential tool for exploring the data. With its large variety of features and its user-friendly handling, TinkerPlotsTM --as a software for learners and teachers--can facilitate the process of comparing distributions. In this article we focus on eight preservice teachers´  reasoning when comparing groups with TinkerPlots. We present ideas on the design of a course to develop statistical reasoning with TinkerPlots, present a framework to rate learners´  performance when comparing groups with TinkerPlots, and present results of a laboratory study about preservice teachers´  reasoning when comparing groups with TinkerPlots. Findings suggest that the TinkerPlots tool and design of the course supported these preservice teachers´  reasoning and that more learning opportunities are needed to increase their group comparison elements´  repertoire and interpretation in context.\r\nFirst published May 2018 at Statistics Education Research Journal Archives</jats:p>"}],"status":"public","publication":"Statistics Education Research Journal","type":"journal_article"}]
