1 Christopher Paolini Computational Science Research Center San Diego State University 100G and Beyond Workshop: Ultra High Performance Networking in California Calit 2 Auditorium First floor, Atkinson Hall UC San Diego La Jolla, CA Tuesday, February 26, 2013 · Campus and Lab Strategies Panel · 11:00AM – 12:00PM

2  University network operations centers support multiple, conflicting missions.  Network Security or Network Performance: which is more important? vs.  NOCs typically accountable to university business divisions and contend with legal and public relations pressures → security wins always.  NOCs not usually accountable to research groups (often never communicate with faculty).  University enterprise (e.g. general purpose/financial/personal) computing: security > performance  Computational and “Big Data” research: performance > security  What can we do to ensure efficient scientific data transfer between universities and national labs?

3  A network optimized for business is not designed or capable of supporting data intensive science.  Universities will always need to support security features that protect organizational financial and personnel data.  Solution: create separate data intensive science network, external to university enterprise network  Design formalized by ESnet, based on traditional network DMZ paradigm

4  Science DMZ: (1) dedicated access to high-performance WAN, (2) high-performance switching infrastructure (large buffer memory), (3) dedicated data transfer nodes

5  Science DMZ using CENIC California Research and Education Network resources

6 Alcatel-Lucent 10 and 40 Gbps switching devices, per CSU policy DMZ spans four campus buildings: Administration, Life Sciences (CSRC Data Center), Education & Business Administration (UCO Data Center), and Chemical Sciences (VizCenter) Primary users: CSRC affiliated faculty and students AL OmniVista 2500 for network management NSF Office of CyberInfrastructure CC-NIE Grant

7 Computational science network connects to the DMZ Funded in 2009 through NSF MRI award Cisco 10 Gbps Catalyst 4900M switching devices CSRCnet spans five campus buildings: Administration, Life Sciences (CSRC Data Center), Education & Business Administration (UCO Data Center), Physics, and Engineering Sole users: CSRC affiliated faculty and students 10G access to SDSC

8  Facilitate high-performance data transfer for scientific applications using Globus Online GridFTP  Alcatel-Lucent OmniSwitch 10K (core device)  Two Alcatel-Lucent OmniSwitch 6900s (satellite devices)  Dedicated and independent 10GE (maybe 40GE) uplink to Internet2 and ESnet via CENIC  Optimized network for high-volume bulk transfer of scientific datasets  Unencumbered, high-speed access to online scientific applications and data generated at SDSU  External access to science resources not impacted by regular “enterprise” or business class Internet traffic  Focus on “BigData” Intensive Science: earthquake rupture and wave propagation, parallel 3D unified curvilinear coastal ocean modeling, geologic sequestration simulation of supercritical CO 2, large-scale proteomic data, bioinformatics of gene promoter analysis, microbial metagenomics, and high-order PSIC methods for simulation of pulse detonation engines  Network performance measurement based on the PerfSONAR framework  InCommon Federation global federated system for identity management and authentication to DMZ connected hosts and services

9  Extension of the standard, two channel FTP protocol  Control Channel ◦ Command/Response ◦ Used to establish data channels ◦ Basic file system operations (e.g. mkdir, delete, etc.)  Data channel: Pathway over which file is transferred  Scheduled transfers using command line interface: $ scp xsede#lonestar4:~/GO/bigdatafile xsede#trestles:~/GO/bigdatafile $ scp xsede#trestles:~/GO/bigdatafile paolini#sdsu:~/GO/bigdatafile

10  Science DMZ performance monitoring accomplished using perfSONAR tool suite  Server side tools run on designated hosts attached to key switches  End-to-end testing with collaborating perfSONAR sites  Determine one way latencies and packet loss between hosts using One-Way Active Measurement Protocol (OWAMP) owping -c i.01 remotedmz  Periodic throughput tests to remote Science DMZs using Bandwidth Test Controller (BWCTL)  Resource allocation and scheduling daemon for regularly- scheduled Iperf tests bwctl -s remotedmz -P 4 -t 30 -f M -w 4M -S 32

11  U.S. education and research identity federation service  Provides common framework for trusted shared management of access to on-line resources  Provide users single sign-on convenience and privacy protection – Shibboleth Service Provider Federating software  Site admins can delegate responsibility for administering service provider (SP) metadata to another admin
