The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced Resource
Connector (ARC).
.
The Advanced Resource Connector (ARC) brings computing resources
together across institutional boundaries. This concept is commonly
referred to as a "computational grid". Historically, grids address the
organisation of distributed storage of data and parallel computation,
but arbitrary services are thinkable.
.
Just like the web, ARC has its roots in the IT infrastructure that was
erected to analyse the experiments for high energy physics at CERN. The
first release, ARC-0.x, was dependent on Globus, the current release
keeps that compatibility but can also be used independently.
.
With ARC-nox, formerly known as ARC-1, the user gains flexibility
with additional services and more supported platforms. The service
developer notices that even for persistent functionality across the
two major versions, what has been a script on the server side once,
that was repeatedly started and ran through, this has now become a
service. Those are only started once and can then be queried, which
is far more efficient, far more responsive, and is no longer stateless
but can observe changes of values over time. |
| nordugrid-arc-nox-arex | ARC Remote EXecution service | Mehr ... |
The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced Resource
Connector (ARC).
.

middleware that is responsible for the execution of compute jobs and
the transfer of input or output data. |
| nordugrid-arc-nox-charon | ARC Charon service | Mehr ... |
The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced Resource
Connector (ARC).
.
Charon is a remote policy decision point service. It accepts formatted
policy decision request and return positive or negative response. When
running a Charon (within the HED), the TLS layer can be used for
securing the communication, when the request or response information
are critical. |

The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced Resource
Connector (ARC).

this client package contains (or depends on) all packages
that are needed to submit jobs, query their status and
retrieve results. |
| nordugrid-arc-nox-compiler | ARC compiler service | Mehr ... |

Connector (ARC).
.
The purpose of this service is to provide compilation capability on the
remote site utilizing its full CPU capacity for parallel compilation
tasks. The service presumes that the compilation task is described in a
usual make file. The current implementation supports GNU compilers only. |

The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced
Resource Connector (ARC).
.
The ARC middleware's core functionality, the Hosting Environment
Daemon (HED) can be extended for novel services. Considerable parts
of a regular installation of a regular installation of the NorduGrid
represent such modules. |
| nordugrid-arc-nox-doc | ARC API documentation | Mehr ... |

and support of the free Grid middleware, known as the Advanced
Resource Connector (ARC).
.
Reference to the ARC programming API. It is prepared with doxygen. |
| nordugrid-arc-nox-hed | ARC Hosting Environment Daemon | Mehr ... |
The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced Resource
Connector (ARC).
.
The ARC Hosting Environment Daemon (HED). This daemon presents a site
to other participants on the grid. An intrinsic component of any grid
system is a mechanism allowing for the secure stateful communication with
remote environments. HED prepares for such an environment and as such
is the core of the ARC middleware. HED was however written in a way,
that represents typical grid computing tasks (the sharing of CPU time
or storage) to become just one possible service between a user and a
remote machine. Many others are thinkable, and HED takes considerable
effort away from the respective implementors. |
| nordugrid-arc-nox-hopi | ARC Hopi service | Mehr ... |
The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced Resource
Connector (ARC).
.
The Hopi service provides a simple implementation of an http(s)
server. It supports GET and PUT operations. It can be used as a simple
file transfer service and it is usable via common web browsers and
other http(s) clients (e.g. wget). |
| nordugrid-arc-nox-isis | ARC Isis service | Mehr ... |
The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced Resource
Connector (ARC).
.
Isis is the new ARC information system implemented within HED. Isis
comes with P2P capabilities and a web-services interface. The new system
grants grid participants an increase in flexibility, robustness and it
also offers easier configuration and self-healing capability. |
| nordugrid-arc-nox-janitor | ARC dynamic runtime environment installation | Mehr ... |
The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced
Resource Connector (ARC).
.
For grid computing, a major challenge is to keep the working environments
homogeneous between the sites. To help this situation, runtime
environments have been developed. Those can be added to or removed from
a site, and this Janitor service helps automating this process.
.
The Janitor is a recent development and the community to prepare
catalogues of dynamically installable packages still needs to evolve. |
| nordugrid-arc-nox-java | ARC Java wrapper | Mehr ... |
The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced
Resource Connector (ARC).
.
Developers with an interest to integrate the some functionality on a
remote site via an interface compatible with ARC, may find it preferable
to perform that remote invocation from within Java. While today most
services in ARC are associated with computation or storage, there is
no constraint on these applications. |
| nordugrid-arc-nox-paul | ARC paul service | Mehr ... |
The NorduGrid is a collaboration aiming at development, maintenance
and support of the free Grid middleware, known as the Advanced Resource
Connector (ARC).
.
The Paul is a pull-based execution service for computing resources. In
these case the computing resource can be single SMP computer. The Paul
uses the iBES protocol to communicate with Scheduler services or any
other service which implements iBES. The Paul can interact with multiple
Scheduler and can controll multiple job in one time. Paul can be used
to run on desktops (MS Windows as well) to form a 'desktop' grid. |
