Project Structure

Work Packages

The DEISA2 project is structured into nine work packages. Two management and communication-related work packages, five work packages categorised into three types of Service Activities (SA), and two Joint Research Activities (JRA). The work packages are structured into tasks and subtasks. Each work package is managed by a work package leader.

The following table lists all the Work Packages of the DEISA2 Project.


Management and Communication-related activities

The management and communication-related tasks are grouped into two work packages. WP1 concerns the overall project management. WP2 comprises external relations, dissemination and training activities.

Service Activities

The tasks of the Service Activities are structured into five work packages according to three different categories of services:

  • Operations: Operation of the DEISA HPC infrastructure (SA1)

    Objective: advancing the persistent distributed European HPC environment to a turnkey operational solution for the European HPC ecosystem (SA1)

  • Technologies: Exploration and adoption of new technologies (SA2)

    Objective: reinforcing the technology roadmap

  • Applications: Applications- and user-related services fostering the exploitation of the DEISA HPC infrastructure (SA3)

    Objective: continuing and advancing computational sciences in Europe

As DEISA is establishing and operating a distributed HPC environment on a continental scale, European-wide operating counterparts of the three departments "Operations", "Technology", and "Applications" which usually constitute the major departments of an HPC centre have to be organized and coordinated. Correspondingly, three European-wide operating teams are being established

  • the Operations Team operates the whole DEISA HPC infrastructure
  • the Development and Technology Team ensures and advances the technological standards across the distributed HPC infrastructure
  • the Applications Support Team supports users and user communities to optimize their benefit from the DEISA infrastructure


Together, these three service activities advance the existing DEISA infrastructure towards an operations model which can be adopted as a turnkey solution by the future European HPC ecosystem. The following figure illustrates the relation and the communication flow between the three Service Activities.


The Operations Service Activity (WP3)

WP3 deals with the day-to-day operation of the overall DEISA HPC infrastructure. The corresponding Operations Team is continuing its collaborative work that started in the previous DEISA1 and eDEISA projects.


The smooth operation of the DEISA infrastructure requires a close active cooperation between the sites' staff members working on the first five tasks.

The local operation teams at each DEISA site are responsible for the DEISA-specific daily work. These teams are led by a site representative who will in turn coordinate all activities between all the DEISA sites. The site representatives ensure that any actions (e.g., local maintenance actions) performed at their site are not interfering with the overall DEISA services and that the quality of service within the HPC infrastructure is not significantly affected.


These site representatives for operations (in the figure they are referred to as “Deputys”) form the Operations Team. The figure above illustrates the services and relations of the DEISA OperationsTeam.

The Technologies Service Activity  (WP4)

The service activtiy in WP4 comprises the roadmap and tasks for exploring new technologies.

The objectives are

  • monitoring technologies already used by DEISA
  • identifying and selecting relevant new technologies of potential interest to the project,
  • evaluating technologies for pre-production deployment purposes,
  • planning and designing specific sub-infrastructures using the selected technologies in order to foster existing services or to deliver new services,
  • deploying and testing the new sub-infrastructures on the DEISA HPC infrastructure in production.




In fact, these five tasks are not independent and partly build upon each other. The following figure illustrates that each objective (A-E) mentioned above is concerned with all the five tasks. 



The Applications Service Activity  (WP5-7)

The Applications- and User-related Service Activitiy (SA3) is structured into three work packages: WP5 (Applications Enabling), WP6 (Environment and User Related Application Services), and WP7 (Extreme Computing Projects and Benchmark Suite).

Two work packages are classified as Joint Research Activities that are relevant for the project: WP8 is dedicated to the development of an Integrated DEISA Development Environment, which is a tool that supports developing applications across the heterogeneous DEISA HPC infrastructure.  WP9 specifically supports WP5 on enhancing applications scalability.
