Infrastructure development (2)

SEE-GRID-SCI infrastructure contains currently the following resources: Total CPUs: more than 3000 Storage: more than 450 TB 44 sites in SEE-GRID-SCI production Typical machine configuration: dual or quad-core CPUs, with 1GB of

RAM per CPU core; many sites with 64-bit architecture


Core services

Catch-all Certification Authority enables regional sites to obtain user and host certificates

Virtual Organisation Management Service (VOMS), For each scientific community deployed in two instances for failover Supporting groups and roles

Workload management service (glite-WMS/LB) and Information Services (BDII)

For each scientific community deployed in several instances for failover Logical File Catalogue (LFC)

For each scientific community deployed in several instances for failover MyProxy

Supports certificate renewal for all deployed WMS/RB services For each scientific community deployed in several instances for failover

File Transfer Service (FTS) Used in production

Relational Grid Monitoring Architecture (R-GMA) Registry and Schema SEE-GRID accounting publisher, with support for MPI jobs accounting

Static Database: HGSM Static database containing all

relevant data about all SEE-GRID-SCI sites

Synchronized with the real situation

Monitoring BBmSAM

Portal that provides access to the database of SAM tests results

Central tools for identification of operational problems

Provides SLA metrics



Gstat Central tool for monitoring of the

information system of SEE-GRID-SCI infrastructure

Nagios Collection of alarms raised by

various tools In the future, automatic creation of

Helpdesk tickets will be implemented

Pakiti Helps the system administrator

keeping multiples machines up-to-date and prevent unpatched machines to be kept silently on the network.

GSSVA (JRA1)



WMSMON Aggregated and detailed

status view of all monitored WMS services

Links to the appropriate troubleshooting guides

Real Time Monitor Using satellite imagery

from NASA, these clients display the SEE-GRID-SCI as it is geographically spread over the region

Googlemap MonaLisa



Helpdesk: OneOrZero Central reference point for tracking

of all operational and user problems Identified problems are reported

through the Helpdesk and assigned to the appropriate supported

NMTT (JRA1)

Accounting portal Collects the accounting data from

all SEE-GRID-SCI sites through apel MPI-enabled accounting publisher developed by the project

Provides aggregated accounting data by site, country, institution, application

Operations wiki

Regional resources for e-Science collaboration

Grid eInfrastructure is by far the largest computing and storage resource available in the South Eastern EuropeHowever, it is only a resource for e-Science collaboration in the region and on the pan-European levelSignificant usage demonstrates already established research collaboration in various scientific fields Meteorology Seismology Environmental sciences

All partners from the region are very open for further cooperation Computer science Physics Chemistry…
