Research Topics

I am interested in the development of novel parallel software tools to speedup scientific computations, such as for the simulation of bioinspired computing models in the fields of Natural Computing and Membrane Computing, or image coding algorithms (JPEG2000 for Digital Cinema Packages and Interoperable Master Format, JPEGXS for lightweight and low latency compression). Tools from High Performance Computing become essential for this purpose, since they enable us to implement real parallelism. Many-core processors, such as GPUs, are good candidates because of their highly parallel architecture, low power consumption, and relatively low cost.


So far, I have been working on the acceleration of P systems simulations by leveraging GPUs with CUDA. At the RGNC (University of Seville), I have developed the first simulators of P systems on CUDA, with the collaboration of researchers from the University of Murcia, Malaga, Philippines Diliman and NTNU.


Furthermore, I am also getting involved in Deep Learning and its potential applications to Digital Cinema and video understanding, collaborating with researchers from Germany and Pakistan. I am also interested in researching new design patterns for parallel scientific computations, in order to help adapting and implementing them to GPU architectures. Other topics I would like to study are also related to the fields of Machine Learning, and Computational Physics and Astrophysics. Although it is a diverse set of interests, I just love science and its applications.


In summary, my research topics today are:


  • Parallel Computing
  • High Performance Computing
  • GPU computing (CUDA and OpenCL)
  • Bio-inspired Computing, Membrane Computing and P systems
  • Simulation and Modeling of Complex Systems
  • Population Dynamics and Systems Biology
  • Deep Learning applications
  • Image Coding in Digital Cinema (JPEG2000)
  • Image Coding in low latency environments (JPEG-XS)

Software Development

I have founded the PMCGPU project (http://sourceforge.net/p/pmcgpu), andcontributed to the P-Lingua project (http://www.p-lingua.org). Both of them are copyrighted works, and published under GPLv3 license.

I have also contributed to the post-production workflow software easyDCPTM, by improving the CUDA JPEG2000 codec and including new functionalities. I provided technical support for this tool.

I have also highly contributed to the Verification Model of the upcoming standard JPEG-XS.

System Administrator

I am one of the main administrators of the High Performance and GPU Computing servers at the Research Group on Natural Computing.

The servers features a NVIDIA Tesla K40 (donated by NVIDIA), 3 NVIDIA Tesla C1060, a NVIDIA GeForce GTX 780 Ti, a NVIDIA GeForce GTX 550 Ti, and a NVIDIA GeForce 9400 GT. They run under a Linux (Ubuntu server 64bits) operating system. More information is available at the official webpage of the computing servers: http://www.gcn.us.es/gpucomputing
