About BalticGrid Project

■ The goal of the BalticGrid project is to extend the European Grid by integrating new partners from the Baltic States (Lithuania, Latvia and Estonia) in the European Grid research community and to foster the development of Grid infrastructure in these countries. To this end, the BalticGrid consortium has enlisted the help of experienced EU Grid computing centres whose aim will be to guide our new partners through the process of deploying Grid resources and applications at their respective institutions.

■ The BalticGrid project started on 1 November 2005 and is a 30-month effort.

NA3 Issues

■ MPI support on clusters■ Standardization of WN (working node) environment■ Software installation on clusters■ Users need User Interface, which solves their problems■ Monitoring of job execution■ Get intermediate results from long running jobs■ Hard to diagnose many problems (unclear error

messages or warnings)

CERN, 2007-03-16 11

GAMESS

■ Preparation for GAMESS VO■ VOMS server installation■ Analysis of source code■ Patches for compilation with PBS/Torque launcher

Use only PBS to launch child processes in another nodes Don't use ssh between nodes – more secure

■ Automatic build and installation script■ Initial deploying and testing■ Later deploying and testing passed to Tomas

Narbutaitis and Eduardas Kutka■ Users are using successfully those installations

SA1 Activity operations

■ Weekly VRVS with 7-9 participants on average■ Joint meetings with NA3■ Very active mailing list, over 1000 mails in 11 months■ Action list http://www.balticgrid.org/Internal/SA1/SA1-

action-list■ 14 open items, 16 closed items■ Collaboration with grid administrators and developers

from Poland, Sweden and CERN has been very useful for Baltic States

SA1 Issues

■ Too many bugs in gLite 3.0■ Too costly installation for small clusters■ MPI support in gLite 3.0 release■ Certification Testbed■ Logging and accounting systems■ Hard to diagnose problems■ 64-bit gLite is not there yet (AMD64/EMT64/IA64)■ Users need User Interface, which solves their problems

basic command line tools – too complicated for ordinary users Proposed solutions:

► Migrating Desktop► P-Grade portal► GENIUS portal► UIPnP with Zeus toolkit
