  2. Intro • What is the supercomputer • Infrastructure • Access to cluster • Support • Log-in http://www.it4i.cz/files/hrbac.pdf http://www.it4i.cz/files/hrbac.pptx

  3. Why Anselm • 6000 name suggestions • The very first coal mine at the region • The very first to have a steam engine • Anselm of Canterbury

  4. Early days

  5. Future - Hal

  6. What is a supercomputer • Bunch of computers • Having a lot of CPU power • Having a lot of RAM • Local storage • Shared storage • High-speed interconnected • Message Process Interface

  7. Supercomputer

  8. Supercomputer ?!?

  9. Supercomputer ?!?

  10. Anselm HW • 209 compute nodes • 3344 cores • 15TB RAM • 300TB /home • 135TB /scratch • Bull Extreme Computing Linux (RHEL clone)

  11. Type of Nodes • 180 compute nodes • 23 GPU accelerated nodes • 4 MIC accelerated nodes • 2 fat nodes
