• connecting geographically distributed clusters into• heterogeneous computing system

• via communication network

• provides efficient infrastructure:

• for heterogeneous computing/modeling procedures

• and comprehensive data maintenance functionality

“The Lithuanian distributed/parallel computing and e-services network (LitGrid)” program is established for such tasks

This program is an NGI for European Grid Initiative and joins/cooperates with FP7 project BalticGrid-II

LitLitGGrid - Technical Infrastructurerid - Technical Infrastructure

• LitGrid now has 13 partners: most active universities, research institutes and colleges of Lithuania

• NREN Litnet provides the network infrastructure with 1Gbps throughput connection between sites

• LitGrid is based on gLite middleware, however several other systems are under consideration (KnowARC, Globus, Cream, Unicore)

• Three sites are running central services (WMS, VOMS, LFC) for LitGrid (at VU, VGTU, KTU)

• All Litgrid clusters have EGEE certified status and are monitored globally (GSTAT, SAM, Stress Test monitors) as well as locally (Ganglia, Nagios)

LitLitGGrid - Central Servicesrid - Central Services

• BalticGrid CA is used for authentication service

• User support is based on a request tracking workflow, which includes e-mail conferencing and a collaborative support system based on request tracking (ticketing) system

• Smaller sites are managed by leading partner VU MIF, with the help of Quattor software

• The site of VU MIF and its central grid services are managed entirely by Quattor also

• LitGrid has a team of well trained and educated administrators as well as RAs, covering most important geographical locations of Lithuania

LitGrid - Cooperation within InSPIRELitGrid - Cooperation within InSPIRE

Lithuanian researchers have many scientific links with Scandinavian countries; participation in EGI-InSPIRE, in the same group with Nordics, Slovenia, Israel, gives advantages:

• Access to the new grid developments, upgrades and other possibilities, to raise efficiency, to share methodical and organizational support of research infrastructure

• Development of joint projects and sharing computing efforts in materials science, medical signal and image systems, linguistics, etc.

• Improvement of Lithuanian cooperation with the European Center of Nuclear Research (CERN), the development of information/data centers in Lithuania (like Tier-3, CERN-CMS-TV)

LitGrid - Ways of CooperationLitGrid - Ways of Cooperation

LitGrid infrastructure will be extended to cooperate:

• with well-known scientific centers and projects, such as CERN, EMBL, PRACE, etc.

• with most essential medical and health care programs (creating suitable virtual repositories, cancer attack diagnostics and prophylaxis, electrophysiological data and analysis, some others)

• with European medical projects, like Health e-Child, MammoGrid, eNMR-grid, cancer monitoring systems

• with institutions of Belarus (UIIP, BNTU, some others), in the area of medical imaging, research and computing in materials science and nanotechnology

LitGrid - the nearest FutureLitGrid - the nearest Future

LitGrid will expand computing resources and research infrastructure (especially grid and cloud technologies):

• to serve Santara Valley science park partners (including Life Science Centre, Innovative Medicine Centre, Life Science Research Centre)

• to offer services for business partners and public sector institutions, as well as for partners of Sauletekio Valley science park and for other science valleys (Santaka Valley in Kaunas, Juros Valley in Klaipeda)

• to serve joint projects with prominent scientists abroad of Lithuanian descent

LitGrid - Infrastructure for Public SectorLitGrid - Infrastructure for Public Sector

The grid technology, HPC and other computing resources have to meet challenges in healthcare:

• Data overload

• Knowledge discovery

• Decision support systems

• Disease models

Grid and HPC infrastructure have to serve:

• Advanced functionality of virtual data repositories

• Computing resources “on demand”

The task for services is to provide effective translation of knowledge into new approaches for prevention, diagnosis and treatment of diseases

ElectrophysiologyElectrophysiology

EEG analysis - research for knowledge discovery and to improve diagnosis (of epilepsy). The processing of measurements of brain activity - electroencephalograms - includes:

• “raw” signal processing• data anonymization• data segmentation with attributed segments• storing them in database with precomputed attributes• computational procedures of data warehousing and data

mining

ElectrophysiologyElectrophysiology

LitGrid resources are provided for grid computing procedures:

• on EEG segments (from database)

• on entire EEGs, primary and secondary attributes of them (such as KDS, KSS, spike index, slow eye movement recognition, distribution of spike appearance time, amplitude, duration, shape, others)

Theoretical models of such data manipulation and computational modeling are based on attributed graphs representation (nodes and edges having parameters and precomputed attributes)

LitGrid also allocate enough resources for data mining analysis (clusterization, recognition, etc.) of all data accumulated in data repository.
