Betzabeth León, PhD student of HPC4EAS, attended ACACES Summer School. This summer school is organized by the HiPEAC Network of Excellence and was held in Fiuggi, Italy from 8 to 14 July 2018.

The ACACES Summer School is a one week summer school for computer architects and tool builders working in the field of high performance computer architecture and compilation for computing systems. The school aims at the dissemination of advanced scientific knowledge and the promotion of international contacts among scientists from academia and industry. A distinguishing feature of this Summer School is its broad scope ranging from low level technological issues to advanced compilation techniques. In the design of modern computer systems one has to be knowledgeable about architecture as well as about the quality of the code, and how to improve it. This summer school offers the ideal mix of the two worlds – both at the entry level and at the most advanced level.

Jorge Villamayor, Ph.D Student working in HPC4EAS research group, was invited to presented his work “Runtime Characteristics for Fault Tolerance: RADIC Architecture” on a European Cooperation In Science and Technology (e-COST) meeting.
The e-COST Action is Runtime Verification beyond Monitoring (ARVI). Runtime verification (RV) is a computing analysis paradigm based on observing a system at runtime to check its expected behavior. RV has emerged in recent years as a practical application of formal verification, and a less ad-hoc approach to conventional testing by building monitors from formal specifications.

This Action aims to build expertise by putting together active researchers in different aspects of runtime verification, and meeting with experts from potential application disciplines. The main goal is to overcome the fragmentation of RV research by

1.   the design of common input formats for tool cooperation and comparison;
2. the evaluation of different tools, building a growing sets benchmarks and running tool competitions; and
3. by designing a road-map and grand challenges extracted from application domains.

Elisa Heymann: New Tutorial on Automated Assessment Tools at the 24th International Conference on Software Engineering and Data Engineering (SEDE 2015).

Software assurance tools – tools that scan the source or binary code of a program to find weaknesses – are the first line of defense in assessing the security of a software project. These tools can catch flaws in a program that can affect both the correctness and safety of the code.
The tutorial will start with basic background material about how software assessment tools work, the capabilities and limitations of such tools. It will then focus on a selection of both commercial and open source tools for C/C++ and Java, and demonstrate how to apply them to sample programs with known flaws. It will conclude with a live demonstration.

Cecilia Jaramillo, Joe Carrión, Zhengchun Liu and Hai Nguyen (HPC4EAS Research Fellows) will assist (14-18 October, 2013) to the BSC PATC Course on Parallel Programming. The objectives of this course is: setting up the basic foundations related with task decomposition and parallelization inhibitors (using a tool to analyze potential parallelism and dependences), and understanding the fundamental concepts supporting shared-memory and message-passing programming models. The course is taught using formal lectures and practical/programming sessions on BSC HPC environment using two programming models: OpenMP for the shared-memory architectures and MPI for the distributed-memory counterparts. Moreover, Paraver will be used as the tool to understand the behavior and performance of parallelized codes.
