SLAC Site Report By Les Cottrell for Ultra. Light meeting, Caltech October 2005 1
SLAC Evolving • Increasingly multi-program: – Increasing focus on photon sources • SPEAR 3, Linear Coherent Light Source (LCLS) and Ultra Fast Science Center – Increased funding from BES • LINAC increasingly funded by BES (all in 2009) – HEP roughly stable, Ba. Bar stops taking data 2008 • Proposal for tier 2 W. Coast ATLAS/LHC site – Accelerator design – NASA (GLAST) and Large Synoptic Survey Telescope (LSST) – Joint (Stanford / Do. E / NSF) funded projects • KIPAC, Ultra. Fast center, Guest House 2
Requires • New business practices – More project oriented since multiple projects so need more accountability – No longer dominated by HEP • Harder to “hide” projects like Ultra. Light/Ping. ER with no sources of funding for operations. 3
UL Testbed 10 Gbits/s • Sunnyvale space loaned from CENIC, SLAC paid for power $1 K/month, stopped being invoiced July ’ 05 – Status of permanent residency unresolved • Cisco 6509 from Ultra. Light proposal • Two Sun v 20 z dual 1. 8 GHz Opterons loaned from SLAC – 10 GE Neterion NICs, purchased by SLAC – Remote management • Purchased/installed terminal server to provide console access • Purchased/installed remote power management • Will get file server from Caltech? • Connect hosts to Cisco 6509, to 10 Gbps Ultra. Light • Tie in/interconnects between ESnet, USN & UL unclear – USN has 2 circuits to UL router – ESnet (SDN) has circuit to USN – ESnet BAMAN has connectivity to SLAC • Main costs to SLAC are people costs for which there is no directed funding to support 4
Sunnyvale set up • V 20 z dual 1. 8 GHz opterons • Linux 2. 6. 13 FAST + Web 100, Neterion 10 GE NICs • NO uldemo account allowed 10 Gbits/s Ultra.
