  1. Rolandas Naujikas Vilnius University Faculty of Mathematics and Informatics Lithuanian Grid activities

  2. VU MIF ITC facilities • 60 Linux x86 computers • 8 Celeron 2GHz, 256MB • 24 Celeron 1.3GHz, 256MB • 8 Pentium III 800MHz, 128MB • 6 Celeron 900MHz, 128MB • 14 Pentium 100-200MHz, 64MB • 25 Solaris computers • 21 UltraSparc IIe 500MHz, 256MB • 4 2*UltraSparc III 1GHz, 2GB

  3. Software • Debian GNU/Linux (3.0 >> 3.1) • Sun Solaris (9 >> 10) • LAM/MPI • BLACS • LAPACK • ScaLAPACK • Sun Grid Engine (SGE) • Sun HPC ClusterTools + S3L

  4. LCG2 test installation • LCG 2.3.0 (>> 2.3.1) • 2 computers: • CE, SE, site BDII • RB, top BDII • no PBS • complicated setup • ...

  5. BGM@VUMIF Cluster • 3 Itanium II computers • 2*Itanium2 1,4GHz, 2GB • 4*Itanium2 1,4GHz, 2GB • 4*Itanium2 1,5GHz, 8GB • Rocks Cluster Linux (RedHat Enterprise Linux) • OpenPBS • Nordugrid 0.4.4 • ...

  6. BGM@VUMIF setup • Some internal IP @ master node • Mapped on firewall to external IP • GridFTP (passive mode) doesn't work • External IP as alias @ master node • Forwarding for FTP from firewall to master • GridFTP work • bgm.mif.vu.lt – fully working NorduGrid node

  7. Let's try • Making of algorithms • Writing of programs • Testing of them • Submitting to grid • Getting results • Analyzing them • Conclusions • Restarting

  8. To Do • Install NorduGrid middleware to access VU MIF clusters • Install more software for parallel computing • Take access to more people • Do more calculations

  9. You are welcome come to us clusters to make together scientific works Rolandas Naujikas Rolandas.Naujikas@maf.vu.lt http://grid.mif.vu.lt (preparing) Welcome to World of Grids
