Enhancing HPC Education and Workflows with Novel Computing Architectures

Enhancing Grid Security Using Workflows, Trusted Computing and Virtualisation

This paper highlights the need to meet both Grid user and resource provider security requirements, describing the rationale for securing Grid workflows: a set of tasks arranged into a logical order to process a Grid user’s dataset. An overview of a secure protocol using Trusted Computing technology is provided, which is further enhanced with platform virtualisation hardware and software. The pr...

Enhancing Energy Production with Exascale HPC Methods

High Performance Computing (HPC) resources have become the key actor for achieving more ambitious challenges in many disciplines. In this step beyond, an explosion on the available parallelism and the use of special purpose processors are crucial. With such a goal, the HPC4E project applies new exascale HPC techniques to energy industry simulations, customizing them if necessary, and going beyo...

Fuzzy Workflows - Enhancing Workflow Management with Vagueness

Workflow Management Systems have proven their positive effects in well-structured procedures. In practice business processes depend on implicit knowledge and require decisions based on unclear objectives. This vagueness of real-world problems isn’t appropriately supported by modelling methods and workflow systems so far. Today the fuzzy set theory is used successfully in systems that provide so...

Shifter: Fast and consistent HPC workflows using containers

In this work we describe the experiences of building and deploying containers using Docker and Shifter, respectively. We present basic benchmarking tests that show the performance portability of certain workflows as well as performance results from the deployment of widely used nontrivial scientific applications. Furthermore, we discuss the resulting workflows through use cases that cover the c...
