Developments

The TAG project is involved, in terms of development efforts, in

development of tools dealing with source-to-source transformations of scientific codes to be executed on grids
development of scientific applications in the field of geophysics and Plasma physics to test the grid tools
contributions to globus and MPICH-G2 when the original software does not fulfill our needs

Contributions

See the list of patches [html]

Testbed

Testbed status

An description of our Grid testbed is maintenained in our CVS server as an XML description.
An XML stylesheet converts it to HTML. It can be browsed here [html][xml]

RSL form

We also use our custom XML stylesheets to build other tools. From the testbed status, we generate an HTML form that allows to build an RSL request : [html].

Specific benchmark

To benchmark processors, we use a custom benchmark based on ray2mesh software. You can get the bench-ray.sh shell script to test a computer (ia32 only for the moment) and compare it to other results.

Applications

Latest archives extracted from the CVS are listed here [html]

Geophysics

The application does seismic tomography in a global Eath model by reconstructingray-paths of recorded seismic rays. Biggest runs up to now have dealt with the ray-tracing of the full record set recorded by the ISC over a one year period.

Plasma Physics

This application is devoted to the numerical simulation of problems in Plasma Physics and particle beams propagation. The leading candidate for magnetic confinement of a fusion plasma is the tokamak. We plan to use the application more intensively iin the near future, as we want to describe the plasma evolution for long time (more than one thousand time iterations).

What would you say about Globus ? A possible answer ....

Some screenshots taken during experimentations. We would appreciate to have a distributed "top" command :-)
