Land consolidation through parcel exchange among landowners using a distributed Spark-based genetic algorithm
(Springer, 2022-12)
[Abstract]: Land consolidation is an essential tool for public administrations to reduce the fragmentation of land ownership. In particular, parcel exchange shows promising potential for restructuring parcel holdings, even ...
Enhanced parallel Differential Evolution algorithm for problems in computational systems biology
(Elsevier BV, 2015)
[Abstract] Many key problems in computational systems biology and bioinformatics can be formulated and solved using a global optimization framework. The complexity of the underlying mathematical models require the use of ...
BPLG–BMCS: GPU-sorting algorithm using a tuning skeleton library
(Springer New York LLC, 2017)
[Abstract] In this work, we present an efficient and portable sorting operator for GPUs. Specifically, we propose an algorithmic variant of the bitonic merge sort which reduces the number of processing stages and internal ...
Facilitating the development of stencil applications using the Heterogeneous Programming Library
(2017)
[Abstract] Stencil computations are very common in scientific codes. Heterogeneous systems achieve good results solving these problems, but their programming is complex because of the ghost regions required in multi-device ...
An automatic optimizer for heterogeneous devices
(Elsevier, 2020-05)
[Abstract]: Codes written in a naive way seldom effectively exploit the computing resources, while writing optimized codes is usually a complex task that requires certain levels of expertise. This problem is further increased ...
Heterogeneous distributed computing based on high-level abstractions
(2018)
[Abstract]: The rise of heterogeneous systems has given place to great challenges for users as they involve new concepts, restrictions, and frameworks. Their exploitation is further complicated in the context of distributed ...
Guiding the Optimization of Parallel Codes on Multicores Using an Analytical Cache Model
(2018)
[Abstract]:
Cache performance is particularly hard to predict in modern multicore processors as several threads can be concurrently in execution, and private cache levels are combined with shared ones. This paper presents ...
Spark Implementation of the Enhanced Scatter Search Metaheuristic: Methodology and Assessment
(Elsevier BV, 2020-12)
[Abstract]
Optimization problems arise nowadays in all disciplines, not only in the scientific area but also in the field of engineering or economics, and in many others. Currently, challenging optimization problems require ...
