Automated and accurate cache behavior analysis for codes with irregular access patterns
(John Wiley & Sons Ltd., 2007-04-03)
[Abstract] The memory hierarchy plays an essential role in the performance of current computers, so good analysis tools that help in predicting and understanding its behavior are required. Analytical modeling is the ideal ...
Parallelization and compilation issues of sparse QR algorithms
(1998)
[Resumen]
La tesis doctoral se centra en el estudio y desarrollo de métodos eficientes para la paralelización de algoritmos de factorización QR de matrices dispersas, La descomposición QR tiene diversas aplicaciones ...
Towards Low-Latency Model-Oriented Distributed Systems Management
(Springer, 2007)
[Abstract] Windows and Unix systems have been traditionally very different with regard to configuration storage and management. In this paper we have adapted our CIM-based model-driven management framework, AdCIM, to ...
Ontological Con guration Management for Wireless Mesh Routers
(Springer, 2009)
[Abstract] Wireless mesh networks (WMNs) are a category of wireless networks that are self-organized, robust and which offer more flexible client coverage with less equipment requirements than wired networks. In WMNs, mesh ...
Program Behavior Characterization Through Advanced Kernel Recognition
(Springer, 2007)
[Abstract] Understanding program behavior is at the foundation of program optimization. Techniques for automatic recognition of program constructs (from now on, computational kernels) characterize the behavior of program ...
Communication avoiding and overlapping for numerical linear algebra
(IEEE Computer Society, 2013-02-25)
[Abstract] To efficiently scale dense linear algebra problems to future exascale systems, communication cost must be avoided or overlapped. Communication-avoiding 2.5D algorithms improve scalability by reducing inter-processor ...
Optimization of Real-World MapReduce Applications With Flame-MR: Practical Use Cases
(Institute of Electrical and Electronics Engineers, 2018-11-12)
[Abstract] Apache Hadoop is a widely used MapReduce framework for storing and processing large amounts of data. However, it presents some performance issues that hinder its utilization in many practical use cases. Although ...
Locality-Aware Automatic Parallelization for GPGPU with OpenHMPP Directives
(Springer New York LLC, 2016-06)
[Abstract] The use of GPUs for general purpose computation has increased dramatically in the past years due to the rising demands of computing power and their tremendous computing capacity at low cost. Hence, new programming ...
A PVM Based Library for Sparse Matrix Factorizations
(Springer, 1998)
[Abstract] We present 3LM, a C Linked List Management Library for parallel sparse factorizations on a PVM environment which takes into account the fill-in, an important drawback of sparse computations. It is restricted to ...
HPF-2 Support for Dynamic Sparse Computations
(Springer, 1998)
[Abstract] There is a class of sparse matrix computations, such as direct solvers of systems of linear equations, that change the fill-in (nonzero entries) of the coefficient matrix, and involve row and column operations ...
