Affine Modeling of Program Traces
(Institute of Electrical and Electronics Engineers, 2019-02-01)
[Abstract] A formal, high-level representation of programs is typically needed for static and dynamic analyses performed by compilers. However, the source code of target applications is not always available in an analyzable ...
ModelTest-NG: A New and Scalable Tool for the Selection of DNA and Protein Evolutionary Models
(Oxford University Press, 2019-08-21)
[Abstract] ModelTest-NG is a reimplementation from scratch of jModelTest and ProtTest, two popular tools for selecting the best-fit nucleotide and amino acid substitution models, respectively. ModelTest-NG is one to two ...
Enhanced global optimization methods applied to complex fisheries stock assessment models
(Elsevier BV, 2019-04)
[Abstract]
Statistical fisheries models are frequently used by researchers and agencies to understand the behavior of marine ecosystems or to estimate the maximum acceptable catch of different species of commercial interest. ...
Hybrid parallel multimethod hyperheuristic for mixed-integer dynamic optimization problems in computational systems biology
(Springer New York LLC, 2019-05-08)
[Abstract]
This paper describes and assesses a parallel multimethod hyperheuristic for the solution of complex global optimization problems. In a multimethod hyperheuristic, different metaheuristics cooperate to outperform ...
Local Rollback for Resilient Mpi Applications With Application-Level Checkpointing and Message Logging
(Elsevier BV * North-Holland, 2019-02)
[Abstract]
The resilience approach generally used in high-performance computing (HPC) relies on coordinated checkpoint/restart, a global rollback of all the processes that are running the application. However, in many ...
Fast search of third-order epistatic interactions on CPU and GPU clusters
(Sage Publications Ltd., 2019-05-27)
[Abstract]
Genome-Wide Association Studies (GWASs), analyses that try to find a link between a given phenotype (such as a disease) and genetic markers, have been growing in popularity in the recent years. Relations between ...
Portable and efficient FFT and DCT algorithms with the Heterogeneous Butterfly Processing Library
(Elsevier, 2019-03)
[Abstract]: The existence of a wide variety of computing devices with very different properties makes essential the development of software that is not only portable among them, but which also adapts to the properties of ...
Supporting multi-resolution out-of-core rendering of massive LiDAR point clouds through non-redundant data structures
(Taylor & Francis Group, 2019-03)
[Abstract]: In recent years, the evolution and improvement of LiDAR (Light Detection and Ranging) hardware has increased the quality and quantity of the gathered data, making the storage, processing and management thereof ...
Parallel feature selection for distributed-memory clusters
(2019)
[Abstract]: Feature selection is nowadays an extremely important data mining stage in the field of machine learning due to the appearance of problems of high dimensionality. In the literature there are numerous feature ...
Easy Dataflow Programming in Clusters with UPC++ DepSpawn
(Institute of Electrical and Electronics Engineers, 2019-06-01)
[Abstract]: The Partitioned Global Address Space (PGAS) programming model is one of the most relevant proposals to improve the ability of developers to exploit distributed memory systems. However, despite its important ...
