The principle goals of this project to provide
and accelerate the transparent integration of NPACI technologies,
resources, and applications into a high-throughput, web-based
solution for performing end-to-end electron tomography for
the biological researcher and to continue to integrate and
harden the use of several enabling NPACI technologies in the
context of key national and international research activities.
This project is refining the use of a centralized
and fully integrated, grid-portal solution (Telescience Portal)
for performing large scale, collaborative, distributed, remote
end-to-end neuro-imaging research. The Telescience Portal,
now in production use, provides a centralized, transparent
scientific workflow for high throughput electron tomography.
From the Portal users have ubiquitous access to grid-enabled
parallel computation, resource scheduling, global Telemicroscopy,
advanced image processing and visualization, distributed/federated
databases, and network enabled data management and archival
systems, all from a secure environment specifically designed
to foster collaboration between researchers and educators.
The Telescience infrastructure/architecture
continues to function as a resource for transitioning major
national infrastructure projects, like the Biomedical Informatics
Research Network (BIRN), to full compliance with the incremental
releases of the NPACI tool suite (NPACkage) developed to support
and instantiate a stable national cyber-infrastructure. In
this context, Telescience continues to shape the continuing
development of middleware technologies that are appropriate
for application technologies and assemblies, such as those
provided by BIRN and PRAGMA.
Telescience plans to distribute and incorporate
the use of regular NPACKage releases to all remote site in
the Telescience infrastructure, initially to test the NPACKage
software, but also as a means to maintain continuity and uniformity
of the Grid middleware tools that are utilized at all Telescience
sites (which includes resources at NCMIR, NPACI, NASA/IPG,
Osaka U. and NCHC). NPACkage components that are currently
in use (or pre-production use) include Globus, SRB, Gridport,
DataCutter, MyProxy and NWS. Integration of other components,
such as Ganglia and MPICH-G2 are currently in developmental
stages.
The expansion of the Telescience infrastructure
and the transition of technologies to other projects, such
as BIRN, will be greatly aided by NPACKage. Due to the fact
that the Telescience leverages many Grid middleware tools,
collaborative sites where the project is expanding often look
to Telescience developers as experts in the installation/administration
of those Grid middleware components. With the growing number
of Grid middleware tools utilized, the requirements for administration
of all Grid tools is growing outside the domain and scope
of Telescience developers. With NPACKage, the installation
of the NPACI suite of Grid tools will be greatly simplified.
The ease of installation for those Grid tools utilized by
Telescience will aid in the expansion of the Telescience infrastructure
and the development of projects, such as BIRN.
