A Microprogrammed Approach for Implementing Statecharts
(Institute of Electrical and Electronics Engineers, 2019-10-21)[Abstract] Statechart diagrams allow specifying complex systems in which there may be several states active at the same time and a large number of events and transitions to evaluate. Statecharts have been found useful in ... -
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 ... -
Accelerating the quality control of genetic sequences through stream processing
(Association for Computing Machinery, 2023)[Abstract]: Quality control of DNA sequences is an important data preprocessing step in many genomic analyses. However, all existing parallel tools for this purpose are based on a batch processing model, needing to have ... -
Acceleration of a Feature Selection Algorithm Using High Performance Computing
(MDPI AG, 2020-09-01)[Abstract] Feature selection is a subfield of data analysis that is on reducing the dimensionality of datasets, so that subsequent analyses over them can be performed in affordable execution times while keeping the same ... -
An approach to support generic topologies in distributed PSO algorithms in Spark
(Armando De Giusti, Marcelo Naiouf, Franco Chichizola, Enzo Rucci, Laura De Giusti. Universidad Nacional de La Plata. Facultad de Informática., 2023)[Abstract] Particle Swarm Optimization (PSO) is a popular population-based search algorithm that has been applied to all kinds of complex optimization problems. Although the performance of the algorithm strongly depends ... -
An Inspector-Executor Algorithm for Irregular Assignment Parallelization
(Springer, 2004)[Abstract] A loop with irregular assignment computations contains loop-carried output data dependences that can only be detected at run-time. In this paper, a load-balanced method based on the inspector-executor model is ... -
Applying dynamic balancing to improve the performance of MPI parallel genomics applications
(Association for Computing Machinery (ACM), 2024-05-21)[Absctract]: Genomics applications are becoming more and more important in the field of bioinformatics, as they allow researchers to extract meaningful information from the huge amount of data generated by the new sequencing ... -
Characterization of message-passing overhead on the AP3000 multicomputer
(IEEE, 2001-09)[Abstract] The performance of the communication primitives of parallel computers is critical for the overall system performance. The characterization of the communication overhead is very important to estimate the global ... -
Clupiter: a Raspberry Pi mini-supercomputer for educational purposes
(Institute of Electrical and Electronics Engineers, 2024)[Abstract]: The main objective of this work is to bring supercomputing and parallel processing closer to non-specialized audiences by building a Raspberry Pi cluster, called Clupiter, which emulates the operation of a ... -
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 ... -
Compiler support for parallel code generation through kernel recognition
(IEEE Computer Society, 2004-06-07)[Abstract] Summary form only given. The automatic parallelization of loops that contain complex computations is still a challenge for current parallelizing compilers. The main limitations are related to the analysis of ... -
Design and Implementation of MapReduce using the PGAS Programming Model with UPC
(IEEE Computer Society, 2012-01-03)[Abstract] MapReduce is a powerful tool for processing large data sets used by many applications running in distributed environments. However, despite the increasing number of computationally intensive problems that require ... -
Efficient Culling Techniques for Interactive Deformable NURBS Surfaces on GPU
(SciTePress, 2016-02)[Abstrtact] InfoValue: NURBS (Non-uniform rational B-splines) surfaces are the standard freeform representation in Computer-Aided Design (CAD) applications. Rendering NURBS surfaces accurately while they are interactively ... -
