A framework and a performance assessment for serverless MapReduce on AWS Lambda

Giménez-Alventosa, Vicent; Moltó, Germán; Caballer Fernández, Miguel (Elsevier, 2019-08)

[EN] MapReduce is one of the most widely used programming models for analysing large-scale datasets, i.e. Big Data. In recent years, serverless computing and, in particular, Functions as a Service (FaaS) has surged as an ...
Aplicación de la computación de altas prestaciones y computación distribuida en cálculos de Física Médica y radioterapia basados en Monte-Carlo

Giménez Alventosa, Vicent (Universitat Politècnica de València, 2017-10-26)

[ES] Actualmente el cáncer es responsable del 25% de todas las muertes de la UE y es la causa de mortalidad más importante de las personas entre 45 y 64 años. Por lo tanto, la mejora en los tratamientos tendrán un gran ...
APRICOT: Advanced Platform for Reproducible Infrastructures in the Cloud via Open Tools

Giménez-Alventosa, Vicent; Segrelles Quilis, José Damián; Moltó, Germán; Roca-Sogorb, Mar (Schattauer GmbH (Methods of Information in Medicine), 2020-12)

[EN] Background Scientific publications are meant to exchange knowledge among researchers but the inability to properly reproduce computational experiments limits the quality of scientific research. Furthermore, bibliography ...
Building blocks of a multi-layer PET with time sequence photon interaction discrimination and double Compton camera

Ilisie, V.; Giménez-Alventosa, Vicent; Moliner Martínez, Laura; Sánchez, F.; González Martínez, Antonio Javier; Rodríguez-Álvarez, M.J.; Benlloch Baviera, Jose María (Elsevier, 2018)

[EN] Current PET detectors have a very low sensitivity, of the order of a few percent. One of the reasons is the fact that Compton interactions are rejected. If an event involves multiple Compton scattering and the total ...
PenRed: An extensible and parallel Monte-Carlo framework for radiation transport based on PENELOPE

Giménez-Alventosa, Vicent; Giménez Gómez, V.; Oliver-Gil, Sandra (Elsevier, 2021-10)
Plataformes avançades en el Núvol per a la reproductibilitat d'experiments computacionals

Giménez Alventosa, Vicent (Universitat Politècnica de València, 2022-07-07)

[ES] La tesis presentada se enmarca dentro del ámbito de la ciencia computacional. Dentro de esta, se centra en el desarrollo de herramientas para la ejecución de experimentación científica computacional, el impacto de la ...
Strategies of statistical windows in PET image reconstruction to improve the user s real time experience

Moliner Martínez, Laura; Correcher Salvador, Carlos; Giménez-Alventosa, Vicent; Ilisie, V.; Álvarez-Gómez, Juan Manuel; Sánchez Góez, Sebastián; Rodríguez-Álvarez, MJ (IOP Publishing, 2017)

[EN] Nowadays, with the increase of the computational power of modern computers together with the state-of-the-art reconstruction algorithms, it is possible to obtain Positron Emission Tomography (PET) images in practically ...
TaScaaS: A Multi-Tenant Serverless Task Scheduler and Load Balancer as a Service

Giménez-Alventosa, Vicent; Moltó, Germán; Segrelles Quilis, José Damián (Institute of Electrical and Electronics Engineers, 2021)

[EN] A combination of distributed multi-tenant infrastructures, such as public Clouds and on-premises installations belonging to different organisations, are frequently used for scientific research because of the high ...
The PENELOPE Physics Models and Transport Mechanics. Implementation into Geant4

Asai, Makoto; Cortés-Giraldo, Miguel A.; Giménez-Alventosa, Vicent; Giménez Gómez, Vicent; Salvat, Francesc (Frontiers Media, 2021-12-14)

[EN] A translation of the penelope physics subroutines to C++, designed as an extension of the Geant4 toolkit, is presented. The Fortran code system penelope performs Monte Carlo simulation of coupled electron-photon ...
TOF studies for dedicated PET with open geometries

Moliner, L.; Ilisie, V.; González Martínez, Antonio Javier; Oliver-Gil, Sandra; Gonzalez, A.; Giménez-Alventosa, Vicent; Cañizares, G.; Lamprou, E.; Alamo, J.; Rodríguez-Álvarez, María José; Sánchez, F.; Benlloch Baviera, Jose María (IOP Publishing, 2019-02)

[EN] Recently, two novel PET devices have been developed with open geometries, namely: breast and prostate-dedicated scanners. The breast-dedicated system comprises two detector rings of twelve modules with a field of view ...
