LAM/MPI 7.0 has escaped!

The LAM Team from the Open Systems Lab at Indiana University is pleased to release LAM/MPI version 7.0. Representing over two years of development, version 7.0 includes significant new features for MPI applications programmers, parallel programming/MPI researchers, and system administrators. An abbreviated listing of these features includes: * When used with the Berkeley Lab Checkpoint/Restart (BLCR) single-node checkpointer, parallel MPI jobs can be involuntarily checkpointed and restarted. * Low-latency, high-bandwidth message passing on Myrinet networks. * Extensive run-time tuning and underlying network selection (vs. compile-time selection and tuning). * SMP-aware collectives. Based on the MagPIe algorithms, several of LAM's MPI collective functions have been optimized for use in networks of SMPs. * Integration with PBS, BProc, and Globus. LAM now uses the native job starting mechanisms of each of these environments to launch jobs in parallel. * A comprehensive User's Guide, providing a user-centric description of LAM/MPI, how to use all of its features, and how to tune MPI applications at run-time. * An extensible component architecture such that MPI researchers can write small, self-contained components that "plug-in" to LAM/MPI. * Support for the TotalView parallel debugger. More information and documentation is available at the newly-redesigned LAM/MPI web site: "http://www.lam-mpi.org/":http://www.lam-mpi.org/ Make today a LAM/MPI day!

The Good, the Bad, and the Beauty-Impaired

I finally made the switch to procmail. I got kinda burned this past weekend with pine making lots of duplicate filter messages because of IMAP disconnects, so I finally decided that it was time to switch to server-side filtering. At the same time, I noticed that I had missed about 10 important e-mails in my spam folder over the past month, and decided to switch to a different spam-filtering system. So I'm now using "procmail":http://www.procmail.org/ (which rocks -- it was easier than I thought to setup, and it can things that I was unable to do with pine's native filtering) along with "bogofilter":http://bogofilter.sf.net/, the Bayesian spam filter written by ESR and company. So far, I'm pretty happy. I had lots of spam to train bogofilter with, but I still have to correct it every once in a while (and I'm sure it's partly due to the fact that the spammers are catching on to the Bayesian filters and are working around them with random letter clusters, etc.). The switch to procmail has been particularly important because I've had a few brownouts lately due to thunderstorms, and my IMAP connections get broken. This would have resulted in duplicate filtered message before, but not with procmail. Yippie!

A friend of mine is considering switching from "slimy contractor" status to "useless/stupid" government status. Another friend of mine just made the opposite decision (i.e., retired from military and got a contractor job). Best of luck in making the decision!

I enabled the status messages display in my main gaim (instant messanger) window. This results in the window being significantly bigger. Thought you'd all like to know.

Kind of a ring thing, comes with a "dialer", you hit the symbols, it spins around, lights come on, kinda flushes sideways...?

I just noticed that my Dirty Vegas oggs (effectively "MP3s" for those of you who don't know what oggs are) are not on my main desktop machine. They only exist on my laptop. And here I was wondering yesterday when I was listening to DV on my laptop why it seemed like I hadn't heard those songs in a long time. [SMACK] It's because I *haven't* heard them in a while. Duh!

Haiku of the day: Ribbeldy bop do, Blipenperspiel klak perplak. Makelfod. Splat. Splat.

Bad joke of the day: I used to think that memory is important. But I just can't remember why.

Worse joke of the day: A horse walks into a bar. The bartender says, "Why the long face?"

Two pops don't make a thunk

A real-life experience from a friend:
While in Oregon last week I observed this on a bumper sticker; "Remember, I'm just as BAD a driver as you". Made me stop and think.. How does this person know how bad a drive I are anyway... Needless to say, I stop following that car as soon as possible. I may be crazy but I not going to allow anyone to out class my driving skills or lack of...

There's no Mayan god named "Fred"! ...sure there is.

Well, I tried. I upgraded my Laptop from Mandrake 9.0 to 9.1 last night. It went pretty well; I had to reset a few things (X settings, audio settings, etc.). But for the most part, everything went smoothly. The major reason for my upgrade was to get the latest version of Evolution. I was hoping to consolidate my Palm Pilot data with e-mail, calendaring, etc. I first tried the Evolution that ships with MDK 9.1 (v1.2.something), but eventually downloaded the latest direct from Ximian (v1.4). I was a bit surprised to see how flaky it was. Sometimes buttons didn't work (i.e., click on it and nothing happens), weirdness with expunging my IMAP mailboxes (I have 2), and pretty much total failure trying to synchronize with my Palm Pilot (it grabs about 20 addresses and then times out). So I'll stick with pine for now. Pine is great, but lacks offline capabilities (and of course, integration with calendaring, etc.). Evolution also has better searching capabilities (local caching, etc.). So I was kinda hoping that it would work out. Alas. Evolution looks very promising and very slick -- don't get me wrong -- it is just apparently not suited for what I want to do. Bummer!

Had a bunch of friends over for dinner last night which was fun. Jim A. and Daraius P. will be going with me to the Ft. Knox Zussman MOUT (Military Operations Urban Training) in a few weeks with my army unit for the urban training exercises. Should be fun.

Can't remember if I mentioned this in jjc or not -- but since we have subscribed to DirectTV, we no longer see cable commercial ads. Instead, we see DirectTV ads. Clearly, there must be some kind of slot for "local provider" commercials (or the provider simply chooses to fill them with their own ads). With today's direct marketing methods, I wonder how targetted these commercials are? I notice that we see few (if any) commercials for the DTV package that we have -- instead, they're all "upgrade" kinds of commercials (get this sports pack, or this movie pack, etc.). How much of this world have we surrendered (without a fight) to the lawyers and marketers?

All your root are belong to us

Brian works in the same building as the F root server. That's so cool.

Not so much

Yesterday was Tracy's and my 3rd anniversary. Yay us!

Brian is thinking of buying a "Tivo":http://www.tivo.com/. Everyone should encourage him to do so.

One of my internet service addresses (i.e., the "whois" e-mail contact address for one of my domains) was spammed by "Indiana Wesleyan University":http://www.indwes.edu/ yesterday (including the usual lame comment that I had subscribed to receive such notices -- which I most certainly did not). While this is not a new tactic for spammers, I'm surprised and saddened that an insitute of higher learning has resorted to such fradulent tactics to recruit students.

Shiny boots and a spanking clean haircut, and you can handle the world

There's a new humorous Mac G5 commercial on TV that shows a man getting forcibly blown out of his house, supposedly because the G5 is so powerful/fast. And what did my wife notice about this commercial? That there's a GE Advantium in the kitchen. [sigh]

_Fight Club_ is a really good movie. So is _Apollo 13_, (which was on TV last night, and I have the DVD of it). It's the official "It's Cool To Be An Engineer" movie.

There's nothing like rollerblading on brand new wheels and bearings. "Smooooooth" is perhaps the best way to describe it. You slither over the street and slip around corners. "Whoosh", to say the least. It's always incredible going for the first blade after having run old wheels/bearings into the ground -- the difference is astronomical. You can corner like nobody's business, at speeds that were totally impossible on your previous wheels/bearings. You don't blade. You glide. You glide really, really fast. It rocks.

Really old reference

So Mark S asked for it. Several years ago, I was rollerblading home from work with my palm pilot in my pocket and a wheel popped off my rollerblades and I fell. On my palm pilot. The screen shattered in a spectacular way. Mark asked that I publish this image again, so here you go (well, ok, he didn't ask for it -- I'm doing it just to spite him):
I made one reference to this dead palm pilot in "a previous journal entry":http://jeff.squyres.com/journal/archives/000363.php, but the image link was broken. I've now fixed it. Also note that I still have the 5th pilot referred to in that entry (and am still actively using it). Does that make it the one that has lasted the longest?

Teal'c's seen it 8 times. 9 times.

Updates: * I've started "using encryption":http://gaim-encryption.sf.net/ in IM sessions (thanks to Dave L. for suggesting it). * "Brian B.":http://bbarrett.livejournal.com/ has joined the Tivo generation. * Johnny S. has finally taken the Linux plunge. * Jeremy S. has gotten engaged. * Arun R. hasn't filed a blog entry in months. I suspect a devious plot. * Perk, to my knowledge, is still homeless. By choice. * CPT Klak is back from Kuwait. She gets her own company command in a few days. * Sriram S. refuses to admit that he has a vi problem. * The moon is made of green cheese.
