Somniloquy: Most of Microsoft's research efforts
are in software, but one of the more exotic displays from Wednesday was
Somniloquy, a raw-looking USB drive sticking out of a desktop PC.
Somniloquy is the term for talking during sleep, which is
essentially what it allows a PC to do. When PCs go into sleep mode,
they lose the ability to communicate on networks. The only alternative
is to leave the PC on, which constantly draws power.
Business users often leave their office PCs on overnight to allow
remote file access, and consumers tend to leave them on for overnight
BitTorrent downloads or constant VOIP presence, said James Scott, a
Somniloquy lets a computer go to sleep yet maintain a presence on
the network. It has an SD Card for memory, so it could continue to
download or even share files. It can also maintain a VOIP connection,
waking up the PC when a call comes in. Somniloquy can also wake up the
PC if someone is trying to remotely access the machine.
The power difference is astounding: Scott showed the desktop
computer was consuming around 85 watts of power, but with Somniloquy,
it consumes only around 4 watts. That small amount of power is used to
maintain the DRAM state and power Somniloquy.
"Instead of having computers as all-on or all-off we want more
finer-grained tiers of functionality in the computer so that when the
user is not there you don't need the graphics card on, you don't need
the CPU on," Scott said.
In order to run BitTorrent or VOIP, Somniloquy would need to run
application "stubs," or a stripped-down versions of an application with
no user interface but capable of handling network protocols, Scott said.
Since Microsoft doesn't make networking hardware, Somniloquy might
be more appropriate for companies such as Intel or Broadcom to produce,
HomeWatcher: Microsoft's HomeWatcher is a small
application that shows the amount of data downloaded and uploaded by
users of a particular PC.
Consumers often don't have an easy way to monitor their broadband
usage, which can cause frustration when broadband connections may not
be working well, said Tim Regan, a research software development
"You don't want to know about your central heating unless you're
bloody freezing -- then you do," Regan said. "It's those moments. One
side of it is how do we apportion blame among ourselves. The other side
is how do we become more sophisticated in what we're asking for."
As demand for bandwidth and overall broadband data consumption
increases, Regan said HomeWatcher could prompt more inquisitive
questions from consumers over how they manage their network.
Later this month, Microsoft plans to trial HomeWatcher in a few
homes. Those testers will likely be able to mount a small screen near
their computer that shows the data or can opt to use a desktop,
Flash-based widget, Regan said.
Everest: This software application allows the
redirection of input and output calls from one server to another. One
of the advantages is that Everest allows a disk that is receiving lots
of write requests to allow another disk to handle that load, either on
the same server or one nearby.
"During a period of high load, the normal system can only really get
about 100 requests per second for this particular brand of disk,
whereas if you enable Everest, then we can get up to 200 requests per
second," said Austin Donnelly, a research software design engineer.
"That's quite an improvement in the request rate."
Data that is written to another server is
eventually copied back to the original file server, Donnelly said. "You
can think of it as opportunistic use of spare resources," he said.
Everest also can cut data-center energy use. Since
Everest allows administrators to direct input and output calls, during
certain times one server can be designated to handle all of them. The
rest of the servers in the rack can then be shut down, Donnelly said.
Microsoft has been working on
Everest for about two years and experimented with it on the company's
SQL Server product. Donnelly said Everest is fairly mature, but no
decision has been made yet about when or how it will become a product.
"We'd love to see this in Windows 7 but this is a research project," Donnelly said.
There is already a program called Everest... it's a diagnostic & benchmarking tool.
very interesting, great move microsoft is still sitting in a pile of billions so why not put it into researching more effecient hardware, software! great move thumb up!
