• OpenMP 3.0 Specs Approved The OpenMP Architecture Revew Board approved the 3.0 specifications at
their meeting this morning. The 3.0 draft specifications were out for
public review from October thru January. The final 3.0 specs will be
released on openmp.org next week. It corrects a number of typos,
clarifies some issues raised during the review period, and contains
completed appendicies and lists of examples and implementation-defined

• New OpenMP.org Website 
The OpenMP.org website has a new look. The site maintains the current and draft specifications for the OpenMP API for parallel programming. A few months ago, the people in charge of OpenMP asked me to help them upgrade the site. So I installed WordPress and based the entire site on it. It's now much more friendly and interesting. And, I'll be staying around as webmaster for the site thru the end of the year. We're planning to work together with the OpenMP community site, compunity.org, to provide supporting information about OpenMP. OpenMP is gaining in popularity as more and more shared-memory multicore platforms appear.

• Ubuntu 8.04 Today I installed Ubuntu 8.04 on a discarded Dell Latitude x200 laptop that one of my neighbors was disowning after upgrading a MacBook Pro.
This was good because my wife was needing a cheap laptop just to be able to check email when travelling. Originally, this laptop was running Windows 2000. It's a 800 MHz Pentium III with a 60 GB drive and a pretty dead battery. Just a perfect opportunity to wipe Windows and install the new release of Ubuntu. Installation went pretty well. I used my Mac to download and burn the CD ISO image of the 8.04 release candidate. And then I booted up the CD on the Dell. Note however that this laptop does not have an internal CD device. It uses a USB external drive, which slows down the installation process considerably. And during the install I made the mistake of choosing to look at the release notes first by clicking on the invitation to do so from the install dialog. It took about an hour for Firefox to load from the CD drive! And then I couldn't quit from it. So I started all over again, this time ignoring to Read The Release Notes. The rest went surprisingly smoothly. The trick was to immediately check for updates using the system updater. There were over a hundred updated packages, I guess in preparation for the official release of 8.04 on Thursday. Firefox 3 was already installed, but not Thunderbird. The Synaptic Package Manager discovered the Mozilla-Thunderbird 2.0...12 release and installed it. I couldn't get the Dlink Air-Plus 650+ card that came with the laptop to work. But I did have an AirLink 101 card and it worked! So except for the battery, it seems to be working really well. I had a couple of freezes that required reboots. But that seems to have corrected itself. I think my wife is going to be happy with Ubuntu. Total cost will be just for a new battery ($60-$99). I'm impressed.

• HPC Planet Created planets.sun.com is currently in beta, but it is alive and working. It's a configurable feed aggregator that is available to Sun employees to use to create specialized "planets" of feeds.
I just created one for High Performance Computing at planets.sun.com/HPC. It collects the feeds from blogs.sun.com that are marked with category HPC. It also subscribes to a set of Sun user forums on forums.sun.com, and the news feed from the HPC portal, hpc.sun.com I don't know if this is at all useful. It could be. But it is clear that the amount of information related to high performance computing on the web is overwhelming. Let me know if you find this useful. I will be expanding it to include feeds outside sun.com and with a wider set of categories. But remember: Aggregate, don't aggravate.

• New Sun Technology in the NY Times  John Markoff has an article in today's New York Times about some new techology coming out of Sun Labs that uses lasers to connect chips rather than wires.
"Sun Microsystems
is trying to do for computing what all the king’s horses and men failed
to do for Humpty Dumpty. For decades, the semiconductor industry has
broken silicon wafers into smaller chips to improve manufacturing
yields."

• Two Days Off To Hack  I took two days off work hacking. I mean hacking code, not
coughing.
I've resurrected my three no-longer-functioning MT-based blogs into
new editions using WordPress.
It was an interesting exercise. Had to spend some time grokking PHP.
I chose different design theme for each of the three blogs, which means
learning three different template structures all based on PHP. And
every theme needed a hack.
There are still some tweaks I need to make this weekend. Like making
the "previous" link on the very last entry link to the newest entry in
the old MT blog. This will make the transition seamless, I hope.
But it looks pretty good.
The difference between WP and MT is that the WP pages are generated
dynamically everytime you call one up. But MT generates static pages
everytime you add a new entry. So the MT pages are still there on the
server.
The WP pages are totally dependent on the viability of the mySQL
database. Should that get corrupted, or the mySQL server be down, no
pages. I understand that there is a utility that will generate a
snapshot of the blog in static pages. I just have to find it.
It was fun spending two solid days with just one project. I was even
dreaming in PHP at one point.
It's also interesting to see how the three programmers who created the
three themes I'm using solved the same issues in three very different
ways. But still I was able to borrow features from one theme and insert
it into another.
The photo blog is the most complicated. That may be because the
designer/programmer is German. Many of the comments in the code are in
German, and I had to translate some of the content because it wasn't
all fully localized for English.
Once I got a blog looking usable, I switched over by adding a webserver
redirect via the site's .htaccess file. This tells the webserver, for
example, to redirect rchrd.com/blog/index.html to
rchrd.com/blog/wp/index.php, and that makes the blog live! I also made
redirects for each RSS feed.
Two very productive days!

• 6 Plays About Infinitesmal Calculus What if a group of playwrights used infinitesmal calculus as a topic for writing plays? See here: A SPECIAL EVENT:
MSRI at Monday Night PlayGround!
6 short new plays inspired by the topic:
The Ghosts of Departed Quantities
(or, Is the Right Answer Enough?)
Berkeley Repertory Theatre
2025 Addison Street
Monday, February 18, 2008
8:00 PM
(but, don't miss the pre-show discussion at 7PM)
http://www.playground-sf.org/monday.shtml
Monday Night PlayGround (now in its 14th season) is a
presentation of 6 short plays written on a common theme. This coming
Monday, the theme will be a mathematical one: "The Ghosts of
Departed Quantities (or, Is the Right Answer Enough?)".
On February 6, a group of mathematicians at MSRI met with
the PlayGround pool of playwrights to try to describe the idea of
infinitesimals, how and why they appeared in calculus, and what the
reaction was, including Bishop Berkeley's famous mocking description
of them as 'ghosts of departed quantities'. The playwrights engaged
the mathematicians in a discussion of the culture of mathematicians,
proofs, certainty, intuition, and a host of other aspects of the
story that naturally came up in the discussion.
Then the playwrights went away to think about the dramatic
possibilities that the topic suggested. They had 5-1/2 days to write a
short play inspired by the topic and 6 of the resulting plays will be
presented this Monday night at Monday Night PlayGround.
It will be a very interesting evening, so we hope you'll
make plans to attend both the performances (which start at 8) and the
pre-show discussion (which starts at 7) with a panel drawn from the
mathematicians who presented the story and the playwrights who wrote
the plays.
More information, including where (and how) to buy tickets,
can be found at www.playground-sf.org.

• Phew - I Almost Lost It All But SXDE Saved Me Phew! I almost rendered my laptop useless. But SXDE saved the day. When I first set up the partitions on my laptop, I allocated 15GB for Windows C:\ and 15GB for Windows D:\ and the rest (90GB) for Solaris. Well, it soon became clear that 15GB was not enough for the C:\ partition. I'd been meaning to combine C and D for some time now. Lately everything I ran on Windows got those Low On Disk Space messages. So my project for the weekend was to merge the two into a larger C:. So, I booted up with my Knoppix live CD and used QTParted to repartition the C: partition to gobble up all of D:. That part seemed to work well. I recalled the last time I used QTParted it didn't mess with the data. And all looked fine, with the C:\ drive now 30GB with 14.5GB used. That is, until I rebooted and discovered that QTParted had munged the Grub boot record. Now there was no way to boot Windows or SXDE. Grub just stared back at me not knowing what to do. With knees shaking and a headache looming, I took a wild guess and figured that if I did another upgrade of SXDE, maybe the installer would recreate the Grub boot menu, restoring the pointers to the Solaris and Windows boot records. Well, it was worth a try. Anything else sounded horrible.
And it worked. I went thru the entire upgrade process again (oddly, the installer didn't ask why I was upgrading when the system appeared to be already up to date), and an hour or so later rebooted and there was the Grub menu looking as it should. Rebooting into Windows I found the C:\ drive with 30GB of space, 14.5 GB in use. It was all there, and it all worked. Tragedy avoided. Time for a beer.

• Upgrading to SXDE 1/08 
The latest release of Solaris Express Developer Edition (SXDE) 1/08 is out (here) and I'm running the upgrade right now on my laptop. Last night I downloaded the ISO image (3.7GB - it took 5 hours) using the Sun Download Manager, and today I burned the ISO onto DVD.
So far so good. These things get easier and easier to do with each release. Stay tuned. Update: Success !! It took about 1 1/2 hours. No problems. We're now on SXDE 1/08.
