SEE-SCI

e-Infrastructure

The regional Grid infrastructure is now fully integrated into the European Grid infrastructure. In the SEE-GRID-SCI project it serves as the basis for enabling new Grid applications from the domains of seismology, meteorology, environmental modelling and environmental protection SEEREN initiative has established regional network and SEE-LIGHT project is currently establishing dark-fibre backbone in the region. Bulgaria now has a GEANT Point of Presence at IPP-BAS.  SEERA-EI will capitalise on this momentum and link national-level programme managers and provide an open forum for information exchange, in order to enable coordination of national programmes in eInfrastructures, and to set the framework for a common regional agenda.

Grid computing resources in Bulgaria

Sites CPU Storage

BG01-IPP 636 1 TB (48TB)

BG02-IM 21 0.01 TB

SALUTE - Stochastic ALgorithms for Ultra-fast Transport in sEmiconductors

SALUTE is a grid application, which integrates a set of novel Monte Carlo and quasi-Monte Carlo algorithms for solving computationally intensive problems from ultrafast carrier transport in semiconductors.

SALUTE studies memory and quantum effects during the relaxation process due to electron-phonon interaction in semiconductors; present version explores electron kinetics in GaAs nano-wires.

Multiscale Atmospheric Composition Modeling

• GRID environment based integrated, multi-scale Balkan region oriented AQ modelling system• Study the atmospheric pollution transport and transformation processes (accounting also for heterogeneous chemistry and the importance of aerosols for air quality and climate) from urban to local to regional (Balkan) scales; • Track and characterize the main pathways and processes that lead to atmospheric composition formation in different scales; • Provide high quality scientifically robust assessments of the air quality and its origin, thus facilitating formulation of pollution mitigation strategies at national and Balkan level.

Conclusion

From the Communication from European Commission “ICT Infrastructures for e-Science” „Research in 2020 cannot be imagined without the intensive use of sophisticatede-Infrastructures, so Europe needs to commit to a renewed strategy to tackle theassociated challenges and priorities.”„Striving for world leadership in e-Science, establishing e-Infrastructures as asustainable utility and exploiting them to promote innovation are the three vectorsof a renewed European strategy to support the ground-breaking science of 2020 andbeyond.”
