[san-tech][03356] 白色LEDで 100Mbpsデータ転送 (100Mbps by white-light LEDs)

EUのプロジェクトで白色 LED可視光を利用して 100Mbpsのデータ転送に

"Data are traveling by light"
 Research News August 2011
 Fraunhofer Institute for Digital Media Technology IDMT

  "Regular LEDs can be turned into optical WLAN with only a few
   additional components thanks to visible light communication
   (in short, VLC). The lights are then not just lighting up, they
   also transfer data. They send films in HD quality to your iPhone
   or laptop, with no loss in quality, quickly and safely."
  "... since scientists from the Fraunhofer Institute for
   Telecommunications, Heinrich Hertz Institute HHI in Berlin,
   Germany, have developed a new transfer technology for video data
   within the scope of the OMEGA project of the EU, its
   implementation in real life is getting markedly closer. At the
   end of May, the scientists were able to present the results of
   the project in Rennes, France. They were able to transfer data
   at a rate of 100 megabits per second (Mbit/s) without any losses,
   using LEDs in the ceiling that light up more than ten square
   meters (90 square feet). The receiver can be placed anywhere
   within this radius, which is currently the maximum range.


[san-tech][03354] Gluster Announces Apache Hadoop Storage Compatibility, August 23rd, 2011

"Gluster Announces Apache Hadoop Storage Compatibility in Latest
 GlusterFS Release"
 August 23, 2011

  "... today announced the release of GlusterFS 3.3 beta 2 which
   includes compatibility for Apache Hadoop. This latest enhancement
   to GlusterFS uses the standard file system APIs available in Hadoop
   to provide a new storage option for Hadoop deployments. With this
   new feature, GlusterFS is the first open source, POSIX-compliant
   file and object storage solution that works with Hadoop. Compatible
   with existing MapReduce-based applications and with the ability
   to co-exist with HDFS, this new functionality opens up data within
   Hadoop deployments to any file- or object-based application,
   providing a broad new range of options for big data deployments."

Titan Summit
Oak Ridge Leadership Computing Facility (OLCF), August 15 - 17, 2011

"The summit will provide a forum for current and prospective users
 to meet with OLCF staff and industry vendors to discuss Titan,
 the next-generation leadership-class computational resource, and
 a significant step towards exascale computing at the OLCF.  Users
 are encouraged to present their application plans for scaling
 to exascale."
