Grid technology
•
• 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

LitGrid - Infrastructure for Academics
•
•
•
•
•
•
LitGrid is designed mainly for academic sector (at a moment)
It operates over 500 processors, over 40 TB storage capacity,
17 clusters, about 90 users, serves numerous scientific research
areas
The analysis, design and test deployment of cloud computing
is currently on the way, in relation to grids
New users and new tasks/areas requiring efficient and high
performance computing for scientific research appear almost
constantly
The authoring, deployment and maintenance of LitGrid CA is
foreseen in a near future
The constant introduction of LitGrid activities/capabilities to
potential users, to public sector and business structures, the
formation of new grid projects are under way

LitGrid - 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)

LitGrid - 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 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, CERNCMS-TV)

LitGrid - 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 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 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
Terena, Vilnius, 2010. May 31 - June 1-2
Electrophysiology
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
Terena, Vilnius, 2010. May 31 - June 1-2
Electrophysiology
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.
