2. Wiki

Wiki-pages with up-to-date technical information about the middleware, downloads, documentation, available resources and services and problem shooting will become available shortly.

3. Introduction to grids

An introduction to the world of grid technology can be found here.

4. Application enabling

An important task of the NorGrid initiative is to enable compute- and data-intensive applications on the grid. This enabling must take into account data set sizes, data transfers over wide-area networks, replication of data, geographically distributed users and heterogeneous computing and storage resources. The most apparent advantage of grid environments today is for scientists that run large series of straightforward compute-intensive tasks with relatively simple input and output requirements. Applications that rely on access to distributed data collections (e.g., shared repositories) or meta-scheduling services can benefit as well.

Researchers that are not familiar with (compute) grid environments will need help to prepare their software applications for the grid. The grid will require working with new tools and interfaces. The NorGrid consortium will assist you in evaluating and preparing your applications for the NorGrid infrastructure. We recommend that you contact UNINETT Sigma for further information.

We welcome proposals from groups of users, projects or virtual organizations who wish to provide grid interfaces and other services for their communities to access the NorGrid infrastructure. Please contact UNINETT Sigma.

5. Get on the grid

You can get involved with NorGrid in a number of ways. On a technical level, individuals and groups can get on the grid by joining an existing Virtual Organization or start their own. They can also join as resource providers. If you are interested in getting involved in any of these levels, send an email to sigma@uninett.no.

The basic steps if you would like to try and grid-enable your application yourself:

  1. Determine whether your target software application is suitable for (and can benefit from) execution in a grid environment. See for example this page for classes of applications that are suitable for the grid.
  2. The default grid middleware that is used by the NorGrid initiative is the Advanced Resource Connector (ARC). You need to install the ARC middleware client on your local desktop. There is a wealth of documentation on ARC middleware. In particular, the ARC User Guide is recommended literature.
  3. Obtain a valid (digital) grid certificate. Certificates are used to authenticate users, resources and services on the grid (based on public key or asymmetric cryptography). You can generate a request for a grid certificate with the middleware client.
  4. Once you have a certificate, contact UNINETT Sigma to get your certificate recognized by the NorGrid Virtual Organization (VO) and get authorization to access compute and/or storage resources for testing purposes. There is a light-weight peer review process to access the national compute and storage resources for testing purposes that will take only few days to complete.
  5. Once your application has proven to be able to make efficient use of the national resources through NorGrid, you can join an existing Virtual Organization or create your own and apply for national resources (for compute time and storage capacity) through the Notur II project.
