Date: Mon, 16 Jul 2012 19:41:03 +0900
"LLNL Takes Lead in Managing the DOE’s FastForward Program"
 08.16.2012, insideHPC

先日担当社が確定した (公式プレスリリースは見つかりませんが)、DOE/NNSAの
Extreme-Scale Computing Research and Development
FastForward Request for Proposals

の Statement of Work (プロジェクトの目標、成果物等、役割分担を明記した
文章) を斜め読みしてみました (SOWの TCO紹介は長いので最後にしました)。
はじめにプロジェクトについて (プロジェクト期間は 2年間)

"The FastForward RFP objective is to initiate partnerships with multiple
 companies to accelerate the R&D of critical technologies needed
 for extreme-scale computing. It is recognized that the broader
 computing market will drive innovation in a direction that may not meet
 DOE's mission needs"

後で紹介する NVIDIAの Bill Dallyの Blogの方が解りやすい気がするので:
"The two-year contract calls for NVIDIA to conduct research and development
 in processor architecture, circuits, memory architecture, high-speed
 signaling and programming models to enable an exascale computer at
 a reasonable power level. The concept is to use thousands of efficient,
 throughput-optimized cores to perform the bulk of the work, with
 a handful of latency-optimized cores to perform the residual serial
 computation." Bill Dally, NVIDIA

International Workshop on
Runtime and Operating Systems for Supercomputers (ROSS 2012)
Held in conjunction with ICS 2012, Venice, Italy, June 29, 2012

"The complexity of node architectures in supercomputers increases
 as we cross petaflop milestones on the way towards Exascale.
 Increasing levels of parallelism in multi- and many-core chips and
 emerging heterogeneity of computational resources coupled with energy
 and memory constraints force a reevaluation of our approaches towards
 operating systems and runtime environments. The International Workshop
 on Runtime and Operating Systems for Supercomputers provides a forum
 for researchers to exchange ideas and discuss research questions that
 are relevant to upcoming supercomputers."

   a Layer 2 overlay on top of Layer 3 networks so virtual network links
   don't break as virtual machines flit across data centers. The Fulcrum chip
   also supports the NVGRE alternative that Microsoft, Intel, Dell, and
   Hewlett-Packard have offered."

NSF Workshop on Social Networks and Mobility in the Cloud
 February 23, 2012 - February 24, 2012

General information
"Social network, mobility and the cloud represent special and unique
 opportunities for synergy among several existing and emerging
 communities that are now often evolving in isolated silos. .....
 ....The potential for cross fertilization among these three areas
 of important research will drive much of the research in academia,
 and the products in industry. It is therefore critical
 that researchers develop a coherent vision for these new directions
 to address a set of diverse topics including designing and
 developing algorithms for large-scale query analysis of mobile
 and social data on the cloud, designing a cloud-based transactional
 model for mobile and social network applications, data storage
 in the cloud, security and privacy of mobile and social network
 applications on the cloud, and addressing the unique characteristics
 of both mobile and social network applications, e.g., data streaming

"Intel's SSD 910: Finally a PCIe SSD from Intel"
 4/12/2012, AnandTech
  "... The first PCB features either two or four SAS SSD controllers, jointly
   developed by Intel and Hitachi (the same controllers are used in Hitachi's
   Ultrastar SSD400M). These controllers are very similar to Intel's
   X25-M/G2/310/320 controller family but with a couple of changes.
   The client controller features a single CPU core, while the Intel/Hitachi
   controller features two cores (one managing the NAND side of the drive
   while the other managing the SAS interface). Both are 10-channel designs,
   although the 910's implementation features 14 NAND packages per controller."
   "In front of the four controllers is an LSI 2008 SAS to PCIe bridge. There's
   no support for hardware RAID, each controller presents itself to the OS
   as a single drive with a 200GiB (186GB) capacity. ..."

"ASHRAE Introduces New Liquid Cooled Datacom Environmental Classes"
 Sep 27, 2011

  ""2011 Thermal Guidelines for Liquid Cooled Data Processing Environments"
   creates data center classes for liquid cooling that can enable fulltime
   economizers for a number of applications in many climates, according
   to according to Don Beaty, chair of the Publications Subcommittee of
   ASHRAE's Technical Committee (TC) 9.9, Mission Critical Facilities,
   Technology Spaces and Electronic Equipment."
  "This whitepaper follows an earlier whitepaper released in May 2011,
   "2011 Thermal Guidelines for Data Processing Environments - Expanded
   Data Center Classes and Usage Guidance," which addresses air cooling
   in data centers and created new data center environmental classes
   which expanded the opportunity for chiller-less data centers
   (fulltime economizers)."

[san-tech][03486] Re: DARPA CLIQR Quest (Cash for Locating and Identifying Quick Response codes (CLIQR) Quest) Challenge

Date: Thu, 22 Mar 2012 08:19:59 +0900

"DARPA Challenge Doesn't Go Viral On Twitter"
 Agency ends two-week QR-related contest--promoted only through
 Twitter, Facebook, and other social networks--without anyone
 finding all 7 posters with special codes.
 March 19, 2012, InformationWeek

  "The Defense Advanced Research Projects Agency (DARPA) recently
   ended its CLIQR challenge without anyone successfully completing
   the contest's full task, giving the agency new insights into
   the effectiveness of social networks versus more traditional
   forms of online communications and media outreach to spread
  "The idea behind the challenge was to get people to respond quickly
   to simulate how citizens might mobilize for aid and relief during
   a time of crisis, according to the challenge's website ..."
  "The key to the challenge was that DARPA did not engage in its
   usual outreach strategy ... Instead, it used Twitter to announce
   the challenge and encouraged participants to use their own social
   networks as well, such as Facebook, to find the posters."
