  1. CrossGrid Testbed Node at ACC CYFRONET AGH Andrzej Ozieblo, Krzysztof Gawel, Marek Pogoda 5 Nov 2001 CGW'01

  2. Summary • What is ACC CYFRONET AGH? • Present and future of ACC • Why ACC Cyfronet for CrossGrid Testbed? • First installations • Next steps CGW'01

  3. CGW'01

  4. What is ACC CYFRONET AGH? • Established in 1973 as an independent, non-profit organization • Since 1999 became a separate unit of the University of Mining and Metallurgy in Krakow • About 60 employees in several divisions • Main goals are to provide to universities and research institutes in Krakow: • computer power combined with wide range of software • communication infrastructure and network services CGW'01

  5. LAN in ACC CYFRONET MAN of Krakow CGW'01

  6. Present and future of ACC Cyfronet AGH Computers (parallel): • SGI 2800 - 128 processors R10000 and R12000, 73.6 Gflops of peak performance, 40 GB of operating memory, 190 GB of disk storage • HP S2000 - 16 processors PA 8000, 11.5 Gflops of peak performance, 4 GB of operating memory, 45 GB od disk storage • SPP1600/XA - 32 processors HP PA-RISC 7200, 7.68 Gflops of peak performance, 2.5 GB of operating memory, 40 GB of disk storage • ??? CGW'01

  7. SGI 2800 CGW'01

  8. Data migration Local access viaFTP and/or NFS Remote access via FTP Hierarchical data storage system HP K400 Server, with UCFM 2.3 (UniTree) software Disk cache Cyfronet LAN Tape libraries (ATL) SCSI SCSI Magneto-optical disks library(HP)

  9. Hierarchical data storage system - features • Automatic data migration to magneto-optical disks and tapes • Each file stored in two copies • trashcan - protection against accidental removal • capacities: • disk cache: 110 GB • M-O library: 660 GB • tape libraries: 17 TB • average file access time: • M-O library: 12 s + 30s/100MB • tape libraries: 3 min + 30s/100MB CGW'01

  10. Present and future of ACC Network: • ACC Cyfronet is the leading unit for the Krakow’s MAN: • main network node in soutern Poland • designer and owner of the fiber-optic infrastructure within the city (links several dozen institutions; approximately 70 km long; ATM and/or FDDI standard) • Provides access to interurban and international connections over three WANs (wide area networks): Ebone (3 Mb/s), POLPAK-T (5 Mb/s) and POL-34 (155 Mb/s) • POL-34 (ATM standard) 155 Mb/s --> 622 Mb/s soon CGW'01

  11. CGW'01

  12. Present and future of ACC Network: • Future is PIONIER (Polish Optical Internet) - high-speed academic network in Poland with its own fiber-optic structure; should be ready in two years • Supercomputing center PSNC in Poznan has already access to GEANT - Gigabit (2.4 Gb/s) Europeen Academic NeTwork CGW'01

  13. Why ACC Cyfronet for CrossGrid Testbed? • Good infrastructure: computer and network resources • High-speed connection with other testbed centers in Europe CGW'01

  14. First installations • PC Linux cluster (8 processors + switch at the beginning) with a simple disk storage system • Switch: at least 8 FastEthernet ports + 1 GigabitEthernet • e.g. BATM 48 FastEthernet + 2 GigabitEthernet, price: ~7500$ • e.g. BATM 24 FastEthernet + 1 GigabitEthernet, price: ~4000$ • Software installation (Globus, middle-ware, etc.) CGW'01

  15. Further plans • Real-time calculations for HEP experiments (future LHC accelerator in CERN) • data transfer speed of 1.5 Gb/s is needed. • GigabitEthernet port for our Cisco Catalyst 8540 (connection with POL-34 network); price: ~17000$; not necessary at the first stage • Heterogeneous CrossGrid node: • including small number (e.g. 8) processors of SGI2800 by using miser or mpset programs offered by IRIX 6.5 • incorporating our hierarchical storage system UniTree + ATL CGW'01
