On High Performance Computing and Grid Activities at Vilnius Gediminas Technical University (VGTU) dr. Vadimas Starikovičius VGTU, Parallel Computing Laboratory dr. Dalius Mažeika VGTU, Parallel Computing Laboratory 2 nd NGN workshop, Estonian Academy of Science, Tallinn 19 – 21 January 2005

Outline  Brief history of high performance computing at VGTU  Parallel Computing Laboratory (PCL)  Computational resources at VGTU  PCL research activities  GRID activities at VGTU  Future plans

Brief history  first PC cluster (2 PC) was build using Linux. PVM.  High Performance Computing project for was supported by Lithuanian Government and IBM.  IBM SP2 was installed and IBM RS/6000 cluster was build.  first PhD theses on parallel computing was defended and Toolkit for sequence code parallelization was developed.  Parallel computing Laboratory at VGTU was established.  PC cluster (20 CPUs) was build (R peak = 28 GFlops)  PC cluster expansion till 36 CPUs (R peak = 130 GFlops)  GRID testbed (VGTU-KUT-BGM)

Parallel computing laboratory (PCL) Main activities Maintenance and development of computing systems Offering free access to computational facilities to all Lithuanian universities and research institutes Consulting, expertise, training and educational activities Research in the area of high-performance computers and parallel algorithms Staff - 5 persons (1 professor, 3 doctors, 1 programmer)

PCL research activities Development of Parallel Algorithms for industrial problems modelling –Nonlinear optics problem –Multiphase flow in porous media –Parallel Discrete Element Method for flows of granular materials. Development parallelization tools –Master – slave automatic parallelization toolkit –Tool for parallelization of Branch and Bound algorithms –Parallel C++ Arrays toolkit

VGTU GRID Build using Globus Toolkit Motivation –basic block in most GRID’s middleware –to get experience building from source configuring services step by step –possibility to include AIX, Windows machines –to test web services based middleware Web Services vs. Pre-WS services Plans: Condor-G, MPICH-G2, GENIUS

GRID testbed VGTU 36CPU PC cluster (GT 3.2) KUT 12CPU PC cluster (GT 3.2) BGM 22CPU Itanium2 (NPACKage GT 2.2.4) C&A 1Gbps

Future plans Participate in LithuanianGRID, forming BalticGRID, NorduGRID Extend computational resourses using EU funds for Lithuanian studies and science infrastructure Extend activities and staff of PCL
