  1. On High Performance Computing and Grid Activities at VilniusGediminas Technical University (VGTU) dr. Vadimas Starikovičius VGTU, Parallel Computing Laboratory Vadimas.Starikovicius@sc.vtu.lt dr. Dalius Mažeika VGTU, Parallel Computing LaboratoryDalius.Mazeika@fm.vtu.lt 2nd NGNworkshop, Estonian Academy of Science, Tallinn19 – 21 January 2005

  2. 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

  3. Brief history • 1996 - first PC cluster (2 PC) was build using Linux. PVM. • 1997 - High Performance Computing project for was supported by Lithuanian Government and IBM. • 1998 - IBM SP2 was installed and IBM RS/6000 cluster was build. • 1999 - first PhD theses on parallel computing was defended and Toolkit for sequence code parallelization was developed. • 2000 - Parallel computing Laboratory at VGTU was established. • 2002 - PC cluster (20 CPUs) was build (Rpeak = 28 GFlops) • 2004 - PC cluster expansion till 36 CPUs (Rpeak = 130 GFlops) • 2004 - GRID testbed (VGTU-KUT-BGM)

  4. 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)

  5. Parallel computing systems at VGTU • IBM SP named Daumantas • 4 Thin nodes with High Performance Switch • Specification of the Node: • RISC POWER2 120 MHz processor • 128MB RAM • 4,5 GB SCSI-2 HDD • 110 MB/s Enhanced Switch Adapter • 155 Mb/s ATM adapter • 36.4 GB SSA disks array • AIX v.4.3.3 • POE v.2.4 (MPI implementation from IBM)

  6. Parallel computing systems at VGTU Self made PC cluster named Vilkas (36 CPU) • Specifications of 16 nodes • Intel Pentium 4 3.2 GHz  Prescott HT • 1 GB 400 MHz DDRAM PC3200 • 200 GB HDD SATA • Gigabit Ethernet NIC • Specifications of the 10 SMPnodes • Dual Intel Tualatin Pentium III 1.4 GHz L2 512KB • 1 GB DDRAM 266 MHz • 80 GB HDD ATA/133 • Gigabit Ethernet NIC • Total: • 36 (16 + 20) CPU • 20 GB RAM • 5.6 TB HDD • Peak performance Rpeak = 130 Gflop/s

  7. 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

  8. VGTU GRID • Build using Globus Toolkit 3.2.1 • 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

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

  10. 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
