Alfonso Laguna, CD.; Hernández García, V. (2013). Performance enhancement of a GIS-based facility location problem using desktop grid infrastructure. Earth Science Informatics. 6(4):199-207. doi:10.1007/s12145-013-0119-1.Performance enhancement of a GIS-based facility location problem using desktop grid infrastructure Andrés García-García (a) , Carolina Perpiñá consisting of a set of the experiments on the case study, concludes that the desktop grid infrastructure is able to use a commercial GIS system to solve the spatial problem achieving high speedup and computational resource utilization. Particularly, the results of the experiments showed an increase in speedup of fourteen times using sixteen computers and a computational efficiency greater than 87% compared with the sequential procedure.
