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)

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)

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)

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 SMP nodes• 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

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 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

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
