Report on the experience (or the proposed activity). It would be very important to mention key services which are essential for the success of your activity on the EGEE infrastructure.
The Computation and Visualization of Plasma Particles in Fusion
Devices app.
has been chosen as a good example of data intensive, interactive
app. that
requires powerful computing resources, advanced visualization and
high
network throughput. The purpose of this app. is exploiting the
combined power
of a high number of CPUs in order to visualize the behavior of
plasmas inside
fusion reactors. It is the most representative use case that
makes usage of
most interactive services developed in the int.eu.grid project.
This concerns a
user-friendly interactive desktop–the Migrating Desktop(MD),
CrossBroker,
advanced visualization services-GVid, usage of PACX-MPI on top of
Open MPI
and glogin. It exploits also such EGEE services, tools and
components like LFC,
CE, L&B, UI, shared resources like SE’s, WN’s. CrossBroker starts
immediately
jobs, and in combination with the MD video streaming service GVid
provides
true steering of the simulation and visualization of the fusion
parallel app.
Describe the added value of the Grid for the scientific/technical activity you (plan to) do on the Grid. This should include the scale of the activity and of the potential user community and the relevance for other scientific or business applications
The main added features of this scientific initiative are:
-Distributed Parallel(MPI) Interactive Computing–interactive
support for parallel
applications, which may run remotely across several sites
-User friendly interactive access to grid infrastructures through
a Grid
Interactive Desktop with powerful visualization
Interactivity is an important feature that gives user possibility
to interact with
application in natural way giving the possibility to change
parameters while
application is running. This interoperable production-level
e-Infrastructure for
demanding interactive app. impact the daily work of researchers.
There is identified number of app. and communities that could
benefit of this e-
infrastructure. This includes: in medicine (Ultrasound Computer
Tomography),in
Environment (Environmental Assessment of Climate-Change), in Fusion
(Visualization of Plasma Particles in Fusion Devices). Project
provides support
for interactive and parallel app. not only at technical level.
With a forward look to future evolution, discuss the issues you have encountered (or that you expect) in using the EGEE infrastructure. Wherever possible, point out the experience limitations (both in terms of existing services or missing functionality)
There are several issues that could be improved. We would like to
mention
some of them (important for our community);It would be very
useful to have
web service access to lcg_utils and lfc functionality;the job
submission time
could be reduced; the time interval between the actual job end
and the
availability of the end of the job information could be reduced
There are many appl. in different fields which relay on the
possibility of having a
fast answer that could benefit for this features.
Describe the scientific/technical community and the scientific/technical activity using (planning to use) the EGEE infrastructure. A high-level description is needed (neither a detailed specialist report nor a list of references).
We would like to present activity that aims supporting demanding
interactive
and parallel application with advanced visualization capabilities
on the example
of Visualization of Plasma Particles in Fusion Devices application.
This activity is done within int.eu.grid
(http://www.interactive-grid.eu) project.
The infrastructure is complementary with the EGEE infrastructure
and inter-
operable with EGEE resources.
We would like to interest new communities in the presented
valuable grid
features.
