Management Structure and Procedures
The management of DEISA concerns the coordination and integration of all the work packages with the aim to operate a persistent distributed research infrastructure. The management concept is effectively equivalent to the management of a continental virtual supercomputing centre involving operations, adopting new technologies, application support, dissemination and research activities. The DEISA project including its associated partners will bring together the leading HPC experts of over 15 European countries and Russia. Their common aim is to integrate a highly heterogeneous supercomputer landscape into a common European HPC ecosystem.
The management structure of DEISA2 has been adapted according to some new objectives of this follow-up project, particularly with regard to the integration of European Virtual Scientific Communities, the Associate Partners and the specific relation between DEISA and PRACE. The early integration and close cooperation with Associate Partners is one significant new aspect of the DEISA2 project which is taken into account by the management structure.
The following definitions describe the constituents of the management structure, their roles and relationship in DEISA2:
|Principal Partners||Project members with a strong commitment to DEISA2. The Principal Partner sites are deeply integrated in to the DEISA HPC infrastructure. They are
identical to the DEISA partners from the FP6 project.
|Associate Partners||In general the coordinators for HPC activities in European countries and Russia. In particular PRACE members, not being principal partners of DEISA will be Associate Partners. All the Associate Partners have HPC expertise and express their intention to collaborate and integrate into the DEISA European HPC infrastructure.|
|DEISA Executive Committee (DEC)
||The principal project management authority. This committee is constituted by representatives of each of the Principal Partners which have full voting rights. In addition, the Associate Partners delegate one member without voting rights to the DEC in order to guarantee that their interests are taken into account. The DEC is chaired by the Project Coordinator (see below). All actions of the chair person which are of vital importance for the partners, especially those which may result in legal obligations for any of them have to be approved in advance by DEC and EDEC.|
| Extended DEISA Executive
||is constituted by representatives of each of the Associate Partners and by six members of the Principal Partners. This committee will act as a consulting board on technical, political and scientific issues focusing on the integration of the centres represented by the Associate Partners in DEISA2. The EDEC communicates with the DEC as well as with the Technical Board on occasion.|
|Technical Board (TB)
||is constituted by all the work package leaders and the Technical Coordinator (see below) who chairs this board. Purpose of the TB is to guarantee the proper performance of the project. It is the highest authority for the deployment and operation of the distributed facility. The Technical Board meets face to face at least twice per year and monthly by telephone or video conferencing. The project coordinator will participate.|
||is acting as an external consulting board on scientific issues, constituted by principal investigators of scientific projects that are executed by DEISA and in particular by representatives of European Virtual Scientific Communities. The committe will conduct external assessments of the operation of the DEISA infrastructure and of the quality of services. This feedback is significant for the evolution of the DEISA infrastructure services.|
|Project Management Team (PMT)||supports the Project Coordinator in the day-to-day management of the
project. It consists of senior experts with strong expertise in managing large
research projects. The PMT is located at the coordinating partner site.
|Project Coordinator (PC)||is the person responsible for the execution of the project plan in fulfilment of the contract with the European Commission. The PC is designated by the DEISA Executive Committee acting as the official representative of DEISA. He has overall responsibility for the project, heads the PMT and chairs the DEISA Executive Committee..|
|Technical Coordinator (TC)
||ensures the proper performance of the technical implementation of the project. The TC has operational authority and arbitration competences
regarding the daily operation of the overall facility. He acts in close
collaboration with the work package leaders and collaborates with the project coordinator
and the DEC. He leads the TB. Possible conflicts arising from the management
will be resolved by the DEC and EDEC using the standard conflict resolution
rules (described in the next section). The TC is responsible for
coordinating the deliverables, collecting the contributions of the involved
partners, and for keeping the deliverable deadlines. The TC reports regularly on the
activity progress to DEC and EDEC.
|Quality Assurance Coordinator (QAC)||deals with quality assurance aspects of the performance of the project. He ensures the achievement of the project objectives. The QAC reports directly to the DEC, is not a WP-leader, and should be as independent as possible.|
|Presentation Team||consists of senior experts and experienced speakers from about five DEISA partner sites who give regularly presentations at important international workshops, forums and symposia with the view to keep in contact with relevant organisations and communities world-wide.|
||catalyses relations with leading HPC
and Grid projects and initiatives.
DEISA Management Structure and communication paths between the instances
The internal assessment of project progress is a principle management task. A hierarchical communication structure is put in place that ensures an efficient project progress control. This structure involves the Work Package leaders that are organized in the Technical Board, the Technical Coordinator, the Project Coordinator, and DEISA Executive Committee. Work Package leaders provide regular progress reports which have to include also concerns about potential deviations from the work plan (time schedule). The Technical Coordinator, in cooperation with the Project Coordinator, review the reports with regard to the overall project objectives, and they keep the DEC informed accordingly.
The essential parts of the reports concerning the progress towards the objectives will be part of the regular management reports to be provided as deliverables.
In the case of deviations from or delays to the work plan, adequate correction measures will be identified by the Technical Coordinator, assisted by the Technical Board, and communicated to the Project Coordinator and the DEC. Ultimately, DEC makes the decision on the implementation of adequate correction measures.
Internal Operational Authority Scheme
The Project Coordinator (DEC chair) collaborates closely with the Technical Coordinator. The Project Coordinator guarantees that higher level project management issues are addressed to the DEC and EDEC. The Project Coordinator can take urgent decisions that are subject to confirmation.
The Technical Coordinator, together with the Technical Board, can take decisions concerning technical affairs. Potential conflicts with the management will be resolved by the DEC and EDEC.
The Work Package leaders coordinate their tasks via the standard communication procedures (mailing lists, phone- or video-conferences, face-to-face meetings). All essential decisions will be discussed in the Technical Board with particular emphasis on potential conflicts.
The external operational authority scheme takes into account:
- the cooperation with the complementary project PRACE. An efficient collaboration of both HPC projects is ensured by a joint DEISA - PRACE working group that consists of 12 members, six delegates from each project. The working group members from DEISA belong also to the DEC.
- the Pan-European scientific scope, in particular
the relations to Virtual Science Communities. The relations to Virtual Science Communities are managed
by WP1 in conjunction with WP2 as one of the major objectives. The implementation of the relationship to a Virtual Science Community is task of the service activities (WP3, WP5,6,7).
the following general relations have to be managed by WP2:
- relations to other EU projects such as EGEE and HPC-Europe
- relations to international HPC projects
such as TeraGrid, NAREGI and APAC
Scientific Management of Computational Resources
DEISA2 is continuing the scientific management procedures established within DEISA1. The scientific management of computational resources is implemented by means of National Scientific Evaluation Committees which perform the scientific evaluation of the DECI proposals based on a ranking of scientific priorities.
The Virtual Science Communities have to specify their scientific priorities internally for using the assigned resources for scientific projects and tasks.
As soon as the required scientific management structures, which are to be established by PRACE at the European level, are in place, DEISA will adopt these mechanisms as far as appropriate. Until then, as an interim solution, the DEISA Executive Committee will decide annually about the fractions of available resources that will be assigned to the different initiatives and projects (DECI, Virtual Scientific Communities, software development projects).
