Consultation on ITU-Academia Collaboration & Int. ITU Kaleidoscope Conference (December 8 & 9-11 respectively​)

ITU-Academia Collaboration and International ITU Kaleidoscope Conference was held at UAB and organized by Dr. Remo Suppi as member of the Host Committee. 

Kaleidoscope 2015: Trust in the Information Society was the seventh series of peer-reviewed academic conferences organized by ITU that bring together a wide range of views from universities, industry and research institutions of different fields. The aim of Kaleidoscope conferences is to identify emerging developments in information and communication technologies (ICTs) and, in particular, areas in need of international standards to support the development of successful products and services.

Kaleidoscope 2015 analyzed means of building information infrastructures deserving our trust. The event highlighted ideas and research that will help ensure the Information Society’s growth in inclusivity and sustainability thanks to its trusted foundations. 

The Conference provided an opportunity to share views on the future of the ICT sector and, in particular, to analyze the notion of “trust” in the ICT context as well as innovations embedding trust into ICT ecosystems and infrastructures to bring greater certainty, confidence and predictability to our interactions within the Information Society.

The 2015 edition of Kaleidoscope contributed to the celebration of ITU’s 150th anniversary, which were held in tribute to the extraordinary innovation of the global ICT community.The story of ITU is one of international cooperation among governments, industry players, civil society and academic and research institutes. ITU has a proud history as a key platform for the international community to bring cohesion to innovation in the ICT sector, and Kaleidoscope 2015 will celebrate academia’s immense contribution in service of ITU’s mission to ‘Connect the World’.

Performance Analysis and Scalability of Parallel Applications

Prof Emilio Luque. Computer Architecture and Operating System Department (CAOS)

HPC for Efficient Applications & Simulation (HPC4EAS). University Autonoma of Barcelona (UAB), Spain


Due to the complex interaction between the message-passing applications and the HPC system, many applications may suffer performance inefficiencies when they scale to a large number of processes. This problem is particularly serious when the application is executed many times over a long period of time.

Based on prediction models, such as PAS2P (Parallel Application Signature for Performance Prediction) (**), with the purpose of making an efficient use of the Parallel System resources, we propose the methodology P3S (Prediction of Parallel Program Scalability), which allows us to analyze and predict the strong scalability behavior for message-passing applications on a given system.

The methodology strives to use a bounded analysis time, and a reduced set of resources to predict the application performance and scalability.

The methodology is made up of three stages:

  1. Characterization step: from the execution of a set of small-scale application signatures, the relevant phases of the parallel application are characterized,
  2. Modeling the application: the scalable logical trace of the application is constructed from the model of the logical scalability, generated for each representative phase of the application. This trace will be used to predict the logical behavior of the application, as the number of the application processes increases.
  3. Predicting the application performance for a specific number of processes

The output of the P3S methodology will be the predicted curve of application speedup.

Based on this information and with the aim of use the system resources efficiently, the users can select the most appropriate resources to execute the application on the target system. We executed from 16 to 256 processors and predicted the computation time up until 4,096 processors. For the tested applications, we obtained an error of less than 9% for the application speedup.
