"CPU間の大容量光インターコネクトに向けて小型のシリコンフォトニクス光源を開発"
光送受信器の送信部小型化と温度調整機構の不要化により、
大容量光インターコネクトの実現に一歩前進
2011年9月16日
http://pr.fujitsu.com/jp/news/2011/09/16.html
"株式会社富士通研究所は、CPU間での大容量・高速通信を可能とする光による
インターコネクト（データ伝送）を実現するために必要となる、光送受信器用
の小型シリコンフォトニクス光源を開発しました。
従来は、光送受信器に搭載される、光を放つシリコンフォトニクス光源と、
光源から発せられた光に情報を乗せる光変調器に温度変化が起こった場合、
光源の発振波長と光変調器の動作波長にずれが生じることにより、光に情報が
乗らなくなる懸念がありました。そのため常におたがいの動作波長を一致
させるための温度制御が不可欠でした。今回、光源の波長と光変調器の
動作波長を自動的に一致させる機構を新しく取り入れることで、従来技術では
必要であった温度調整機構を不要とすることに成功しました。この技術により、
光送受信器の送信部において小型化および従来比2分の1の低消費電力化が
可能となります。
今回開発した技術により、小型で低消費電力な光送受信器を CPUパッケージに
搭載可能になります。将来のエクサフロップス級スパコンやハイエンドサーバ
などにおけるCPU間の光インターコネクトへの適用により、超高速コンピュータ
の実現が期待されます。"
"本技術の詳細は、9月14日（水曜日）から16日（金曜日）までイギリス・ロンドン
で開催された国際会議「8th Group IV Photonics (GFP 2011)」にて発表いた
しました。"

"When deployed in a VMware environment, Fusion's ioTurbine software
dynamically provisions ioMemory capacity and I/O performance across
multiple virtual machines (VMs) by using Fusion's VSL OS Subsystem
to house and serve data for each VM. Tight integration of VSL's
host-based flash management and ioTurbine's cache management
eliminates otherwise redundant mapping functions, maximizing I/O
performance and adding a critical and previously missing piece
to virtualized IT environments - a plentiful supply of scalable,
low-latency I/O."
"Through this approach, Fusion-io unites the benefits of flash and
cache without the overhead costs created by integrating each
technology through traditional architectures using storage
protocols and embedded processors. This solution avoids the need
for expensive, performance-oriented networked storage systems,
SSD arrays and memory appliances that struggle to deliver
performance from the far end of a network, instead allowing
enterprises to use cost optimized shared storage systems."

"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.

まだ GlusterFS 3.3 beta 2レベルですが、
"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
http://www.olcf.ornl.gov/event/titan-summit/
"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."
