Bandwidth to the World Project Status Les Cottrell, 10/20/01 We now have iperf running on about 19 hosts. The aggregate throughput from SLAC to these hosts is about 1.2Gbps. SLAC should be upgrading from an OC3 to an OC12 to ESnet during the coming week. The effect of this on the iperf throughputs will be interesting. For the current throughputs, see http://www.slac.stanford.edu/comp/net/iperftests-html/International-Iperf-Tests.html We are working with our collaborators at FNAL, LANL, Wisconsin, Internet 2 and Rice to either get these sites working or get the final configuration (e.g. host, ports allowed etc.) at the sites set up. To allow customization for the various sites we have developed a configuration file to contain relevant information. For most sites we are able to use ssh successfully to remotely execute commands (such as bbcp, iperf) and also to remotely push updates to the software. We also have bbcp installed and running on about the same number of hosts (not necessarily the same hosts). We are working on automating these measurements too, so we can compare bbcp with iperf. We have also set up a PingER affinity group for SC2001, and can easily review the SC2001 affinity group's RTT, loss performances. See http://www-iepm.slac.stanford.edu/cgi-wrap/pingtable.pl?dataset=hep&file=average_rtt&by=by-site&size=100&tick=last60days&from=SLAC&to=SC2001&ex=none for example. The demo display mock up can be found at: http://www-iepm.slac.stanford.edu/monitoring/bulk/sc2001/iperf-map.gif and has been submitted for inclusion in the Bandwidth Challenge brochure. More details on configurations can be found in the enclosure. We also have QBSS working on the Cisco 6500, see: http://www-iepm.slac.stanford.edu/monitoring/qbss/qbss.html#6509 The Dell machines on which we will run the iperf clients and bbcp at SC2001 have arrived at SLAC. The web page for the project is at: http://www-iepm.slac.stanford.edu/monitoring/bulk/sc2001/ Please verify the collaborators. Let me know if there is anybody I have missed. It would also be good to increase the throughput to some sites. If you have any ideas (e.g. faster interface, machine etc.) let's work on it before it goes public
