On cell phones and swiss cheese

My laptop just suspended itself for no apparent reason.


Is this another symptom of it's impending death? The vertical lines on the screen are damned annoying. The keyboard is becoming less responsive. And now this.

Poor pokey. :-(

pokey has served me well over the years.

However, I just initiated the ordering process for a new laptop from Dell (through IU):

  • Inspiron 4000
  • PIII 900 MHz (the price difference between 900MHz and 1GHz seemed to be not worth it)
  • 14.1 inch SXGA TFT screen
  • 256MB RAM
  • 20GB HD
  • 24x internal CD
  • Pluggable internal floppy (will probably stay on the shelf in my office...)
  • Windows ME (but IU has a site license for Win2K, so I might format and install that)
  • No MS Office; IU has a site license for that as well

  • Port replicator
  • External speakers
  • External mouse
  • External keyboard

Lummy said that I can have one of the extra monitors that came with the machines that we got for the machine room, hence, it wasn't in the actual order. It's shipping directly to Bloomies; hopefully it'll be there next week sometime.

Have you ever had a surreal experience involving C++, three peacocks, a kumquat, and 1977 $10 bill?

Neither have I.

Just curious...

Looks like Lummy and I are traveling to Sandia to see Brian's gig and talk to the folks down there. We'll give some kind of talks about LAM and what we want to do with it w.r.t. fault tolerance, etc. Don't know the exact composition of the talks, nor the exact travel days, but it's likely to be the early part of the week of 25th.

I've had a bunch of really interesting phone conversations and e-mails w/ Brian about this FT stuff w.r.t. LAM. It's very cool stuff. He's doing Great Things with the lamd.

More LAMisms:

  • Dog has started doing LAM stuff. (Did I mention this in jeffjournal before? Short term... what?) He'll be adding TM stuff, which will only benefit PBS right now, but hey, perhaps others will implement it as well. He'll also be adding compile-time and run-time parameter checking disabling, and measuring to see if that actually makes a difference or not.

  • I finally made a breakthrough in the Myrinet RPI last night, and I think that I may have found the last problem (that I'm currently aware of, anyway). The tag/size from a long message ACK was getting trashed before the actual body of the long message was sent back in an obscure race condition because the tag/size was stored in a temporary buffer. This race condition only exhibited itself during long message all-to-all tests. Woof. The solution was to save the tag/size immediately upon receipt -- not difficult at all, but it took forever for me to understand what was going on, what was going wrong, and exactly why the tag/size was getting trashed. I'll run all the tests on all three Myrinet systems that I've got access to and see if I can manage to get a beta out this weekend. Of course, as soon as I type this, I probably doom myself to finding other problems, but we'll see...

  • Network Solutions really sucks. We've copied the DNS zone files from nd.edu to cs.indiana.edu, and they're up and available. I tried to use the NSI web interface thingy to change their pointers for the two top-level DNS servers for lam-mpi.org (and .net and .com), but it wouldn't work. So I called them. I spent over 2 hours on the phone, and they still aren't changed. The first woman that I spoke to was... well, let's just say that she was unhelpful. She finally transferred me to "second level support", where I sat on hold for an hour before giving up and hanging up. That was 2 days ago. I haven't had the strength to call back yet. I feel bad because we continue to impose on the good will of Curt while this continues (it's his DNS server that we're using in nd.edu), and it's of no other fault than the fact that NSI sucks.

I'm still defending the USA down here in Atlanta. We're doing a massive IP number reorginzation tonight -- the changes go live in DNS at 1630 EST. We have a whole class C network to ourselves, are are only using less than half of the available IP addresses. So we're shifting all the IP addrs down to the lower 128 and letting GA Tech have the upper half back. So I'm going to go around to all the machines tonight and reset their IP numbers.

We're moving our servers around, too -- the old mail server is going to be retired (although it will stay on for the next few days, while the new DNS information propagates around).

I did a nessus scan the other day to determine what IPs were being used and which were not (DNS really didn't match what we had at all), and I found an unpatched IIS on one of the windows servers. Gulp. I immediately told my boss about it, and it started what can best be described as a political free-for-all brouhaha.

Suffice it to say that it took about 24 hours to get the machines powered off, and some people were very unhappy about that. They're going to need to be reinstalled, 'cause I'd find it extremely unlikely if no one has cracked them yet -- the IIS doors were wide open, with bright blinking neon lights, "Crack me! Crack me!".

Ah well. It's good to know that good technical sense finally prevailed over the political disputes. What will happen with those machines in the long run has yet to be determined, but at least they're off for now.
