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)

Actualment el càncer és responsable del 25% de totes les morts de la UE i és la causa de mortalitat més important de les persones entre 45 i 64 anys. Per tant, la millora en els tractaments tindran un gran impacte en la ...
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)
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 ...
