Grid Computing

GIRD is a research project with the objective to develop specifications and prototype implementations for the future IT infrastructure for large-scale provisioning of IT services.

The Grid and Cloud computing environments in focus for our research are aimed for datacenters providing the infrastructure for internet-based services, for in-house data departments serving their companies' needs, and for large-scale pooling of distributed supercomputing capacity. Our projects embraces the whole research cycle from basic methodological research on fundamental theory, methods, and algorithms; via system design and implementation of prototype software; to deployment and large-scale test and evaluation.

Below, we present some specific projects, some of which are performed in close collaboration with the High Performance Computing Center North (HPC2N). The project is partly funded by the Swedish Research Council (VR) and EU FP7.

Some ongoing projects

RESERVOIR

RESERVOIR Resources and Services Virtualization without Barriers (RESERVOIR) is a European Union FP7 funded project that will enable massive scale deployment and management of complex IT services across different administrative domains and IT platforms. The project will develop open specifications, architecture, and a prototype implementation of a federated cloud infrastructure. This new infrastructure will provide a foundation for a service-based online economy, where, using virtualization technologies, resources and services are transparently provisioned and managed on an on-demand basis at competitive costs. The RESERVOIR consortium includes 13 partners and is coordinated by IBM Haifa.

SweGrid Accounting System (SGAS)
SGAS SGAS allocates capacity between user groups in collaborative Grid environments by coordinating enforcement of Grid-wide usage limits. SGAS employs a credit-based allocation model where Grid capacity is granted to projects via Grid-wide quota allowances that can be spent across the Grid resources. The resources collectively enforce these allowances in a soft, real-time manner. SGAS is included in the Globus Toolkit 4.

Decentralized Grid-wide fairshare scheduling (FSGrid)
FSGridFSGrid provides three-party QoS support (user, resource-owner, VO-authority) for enforcement of locally and globally scoped share policies. The system allows local resource capacity as well as global Grid capacity to be logically divided across different groups of users. The policy model is hierarchical and subpolicy definition can be delegated so that, e.g., a VO that has been granted a resource share can partition its share across its projects, which in turn can divide their shares between project members.

Decentralized, cross-middleware Grid Job Submission Service (JSS)
JSSThe JSS is a feature-rich, standards-based framework for cross-middleware job submission, that includes a Grid resource brokering service that supports advance reservations, coallocation, and cross-Grid interoperability. The service implements a decentralized brokering policy, striving to optimize the performance for individual users by minimizing the response time for each submitted job.

Grid Job Management Framework (GJMF)
GJMF The Grid Job Management Framework aims to form an easy-to-use job submission platform for collaborative scientific Grid computing environments. The framework comprises a set of Grid services offering functionality for submitting, controlling and managing jobs and groups of jobs. The granularity of job control ranges from a top-level fire-and-forget perspective to individual job management.

Generic Workflow Execution Services

Lightweight and generic workflow execution engines are developed in order to facilitate the construction of various types of workflow-oriented user interfaces and portals, and to facilitate their usage with multiple different middleware.

Grid Portals

For many users, a grid portal is the most convenient way to access various grid resources, i.e., through a standard web browser. The portal offers an easy-to-use web interface to a diverse set of heterogeneous systems (Grids or individual computers). The interface includes support for most everyday user activities such as to submit, manipulate and delete jobs, monitor queues and job status, obtain user-, project-, and resource statistics and information, view job output, etc.

Web Computing Environments for Numerical Software

Some of the more application specific grid and web computing projects are related to the EC funded NICONET project. For example, we are developing a web-environment for numerical computations in systems and control theory in collaboration with TU Berlin and HPC2N.

Remote Execution of Numerical Software

The rapid development of basic grid computing infrastructure put strong demands on development of grid-enabled application software and software libraries. Some of the typical grid resource usage scenarios are based on the underlying idea that all small computations are performed on a single local computer, while large-scale computations automatically are distributed to appropriate and more powerful computing resource on the grid. Example include grid-empowered problem solving environments and web-based science portals.

Software

Software is contributed to NorduGrid/ARC and to Globus, where we also are part of the Globus Academic Affiliate Program. Other major networks in which we participate include RESERVOIR, The NESSI Workgroup on Service oriented Infrastructure, and The CoreGRID Network of Excellence.
