The members of the group José Manuel García Salmerón and Francisco José Orts Gómez attended the eighth edition of the Programming and Tuning Massively Parallel Systems summer school (PUMPS) from July 2 to 6, 2017 in Barcelona and whose organization was in charge of the Barcelona Supercomputing Center, the University of Illinois, the Universitat Politecnica de Catalunya and the HiPEAC network. The objective of the eighth edition has been focused on increasing the skills of researchers and teachers with the most innovative techniques in the development of parallel applications using GPUs.
Some remarkable lectures are Wen-mei Hwu (University of Illinois) and David Kirk (NVIDIA Corporation). Some of the topics that have been covered during the course are:
Deep Learning
OpenACC, Python, and Mathematica on GPUs
CUDA Algorithmic Optimization Strategies
Dealing with Sparse and Dynamic data
Reducing Output Interference
Controlling Load Imbalance and Divergence
Acceleration of Collective Operations
Dynamic Parallelism and HyperQ
Debugging and Profiling CUDA Code
Multi-GPU Execution
Introduction to OmpSs and to the Paraver analysis tool

The member of the group, Nicolás C. Cruz, has successfully finished his first pre-doctoral research stay. He has been working with Dr. Said Salhi, from The University of Kent, at Kent Business School (Canterbury, England), for three months. His experience has been really positive both for his personal and research facets. In relation to his personal facet, he has had the opportunity to meet very nice people, starting from his host supervisor, Dr. Salhi, and discover England. Regarding his research field, he has improved his knowledge about Global Optimization, specifically meta-heuristics, to apply them to heliostat field optimization for solar central receiver systems.

In order to finish this entry, a picture taken in the central area of The University of Kent during the stay is included.

From the 26th to the 30th of June, several members of the High Performance Computing and Algorithms group attended the  International Wireless Communications and Mobile Computing Conference (IWCMC 2017), a well known conference indexed in the CORE B ranking, it was held in Valencia (Spain). We show our progress on mitigating pollution and free riding attacks in fully connected P2P system using the Shamir's Secret Sharing technique. They were very interesting days, especially for training of a PhD because we could learn about many topics such as security, networks or IoT.
