SUMMARY:INDIS Afternoon Keynote
DESCRIPTION:Workshop\nArchitectures, Networks, Security, Workshop Reg Pass
 \n\nINDIS Afternoon Keynote\n\nKeahey\n\nKate Keahey will give the second 
 keynote on "Chameleon: New Capabilities for Experimental Computer Science"
 . Chameleon is a large-scale, deeply reconfigurable testbed built specific
 ally to explore a broad range of different state-of-the-art hardware optio
 ns, assess scalability of systems, and provide conditions that allow deep 
 reconfigurability and isolation so that one user does not impact the exper
 iments of another. It currently consists of almost 20,000 cores, over 5PBs
  of total disk space hosted at the University of Chicago and TACC, and lev
 erages 100 Gbps connection between the sites. The hardware includes a larg
 e-scale homogenous compute partition, as well a diversity of configuration
 s and architectures including Infiniband, GPUs, FPGAs, storage hierarchies
  with a mix of HDDs, SDDs, NVRAM, and high memory as well as non-x86 archi
 tectures such as ARMs and Atoms. To support systems experiments, Chameleon
  provides a configuration system giving users full control of the software
  stack including root privileges, kernel customization, and console access
 . To date, Chameleon has supported 2,700+ users working on over 350+ proje
 cts. \n\nThis talk will describe the evolution of the testbed as well as 
 the current work towards broadening the range of supported experiments. In
  particular, I will discuss recently deployed hardware and new networking 
 capabilities allowing experimenters to deploy their own switch controllers
  and experiment with Software Defined Networking (SDN). I will also descri
 be new capabilities targeted at improving experiment management, monitorin
 g, and analysis as well as tying together testbed features to improve expe
 riment repeatability. Finally, I will outline our plans for packaging the 
 Chameleon infrastructure to allow others to reproduce its configuration ea
 sily and thereby making the process of configuring a CS testbed more susta
 inable.
