The Week in Review


Here's a collection of highlights, selected totally subjectively, from this week's HPC news stream as reported at insideHPC.com and HPCwire.

>>NSF Announces giant and huge supercomputers

NSF has formalized the announcements that were leaked on the internet last week and reported in the New York Times (http://insidehpc.com/2007/08/07/nsf-petascale-story-in-the-nyt/).

University of Illinois at Urbana-Champaign (UIUC) will get $208 million over the next 4.5 years to build a petascale machine named "Blue Waters." The vendor wasn't announced in the release but the name might offer a hint that confirms IBM as reported in the NYT piece.

And the University of Tennessee at Knoxville Joint Institute for Computational Science (JICS) will get $65 million over 5 years to build the Track 2 machine. The UT project includes partners at Oak Ridge (as was rumored), as well as TACC and NCAR.

No official word at this time from NSF or the awardees on what machines are proposed.

>>IBM packs up running apps and moves them around

IBM has started talking about its new Live Partition Mobility technology, now in beta. From their release (http://www-03.ibm.com/press/us/en/pressrelease/22005.wss):

Live Partition Mobility, currently in beta testing with general availability planned later this year, is a continuous availability feature that will enable POWER6-based servers, such as the System p 570, to move live logical partitions -- including the entire operating system and all its running applications -- from one server to another while the systems are running.

This sounds similar to the functionality that Evergrid is currently working on, some of which is deployed. While I believe that neither offering requires users to change their codes, the IBM solution is supported in hardware.

Because Live Partition Mobility is implemented in the POWER6 chip, hardware and its associated firmware, the feature is operating system independent, allowing the movement of AIX or Linux operating systems and associated running workloads. For instance, using Live Partition Mobility customers will be able to dynamically consolidate UNIX or Linux workloads -- without interruption -- onto fewer servers during off-peak times, allowing them to turn off computers and save energy.

The company is talking about this functionality in terms of business apps, of course, but HPC centers could use it to juggle load among machines for better balance, or to make room for high priority applications.

>>Sun launches "world's fastest commodity microprocessor," at 1.4 GHz

Sun is basing that claim on SPEC performance, not clock speed. They are talking, of course, about the UltraSparc T2, formerly known as the Niagara II chip. The chip has 8 cores (the same as the Niagara I), but now has 8 threads per core and a floating point unit with each core (instead of 4 threads per core and 1 FPU per chip). The chip is designed to kick virtualization butt.

The DailyTech has a good, quick overview at http://www.dailytech.com/Sun+Announces+New+UltraSPARC+T2+as+Worlds+Fastest+Microprocessor/article8340.htm.

Interestingly, Sun is going to open source the thing:

Having surpassed 5,500 downloads of the OpenSPARC T1 source code, Sun is working to release source code for the UltraSPARC T2 processor to the OpenSPARC community at www.opensparc.net.

>>The Green Grid announces strategy, timelines

The Green Grid yesterday released details of its near term plans. After getting started just six months ago, the group has come a long way, putting together a solid technical strategy and the core teams necessary to get the job done.

At a press event before the release yesterday, the group reiterated its bottom up focus (partly in response to questions about criticisms from the Gartner Group): start with the data center now, where they feel they can make a near-term impact and get their hands around the problem, and work out to larger issues over the long term when there is a contribution to be made.

The group seems very focused on practical steps, which is refreshing and to my mind indicates that they might actually accomplish what they're setting out to get done. I've outlined their strategy along with the initial deliverable schedule at http://insidehpc.com/2007/08/08/the-green-grid-announces-strategy/. The schedule is ambitious: the group plans to deliver nine major documents between now and the end of the year.
