SGI Files for Bankruptcy – No Surprise

I was a strong advocate of moving our lab away from SGI, which was expensive and slow for our purposes, and on to Linux.

WSJ.com – Silicon Graphics Files For Chapter 11 Protection

Silicon Graphics Inc., a long-struggling maker of high-performance computers, filed for Chapter 11 bankruptcy protection.

A group of bondholders agreed to trade their debt for a stake in the company, which filed for Chapter 11 protection Monday morning in U.S. Bankruptcy Court in New York.

Silicon Graphics is known for desktop workstations and larger server systems that are favored by engineers and others who demand sophisticated graphics, including Hollywood studios. But the company has suffered a long slide, partly due to competition from machines based on standard components used in personal computers.

Trayanova lab in Tulane University Magazine

We made the Tulane University Magazine – an online thing where Tulane puts stuff they think they should tell the Tulane community and the world. They made a few mistakes (biomechanical engineer?) but I think it’s a nice picture. It reads pretty much like any generic story about our lab.  Notice Rob and I using the 30″ cinema display in the background.

Tulane University Magazine – News

The subtle rhythms, pulses and patterns of the human heart have fascinated poets, lovers and scientists alike for millennia, yet the heart’s deepest secrets remain tightly locked. Tulane biomechanical engineer Natalia Trayanova and her team may have the most incisive insight into the heart’s electrical signals, with a three-dimensional virtual model that demonstrates cardiac activity from cellular to organ level.

The Paper and Writing Daily

I’ve been working on this paper for some time, and it’s become clear that if I’m to finish it by the deadline I must make a dogged effort to devote time to writing it regularly: writing occasionaly for hours at a time hasn’t been working for me.

Today is the first day. I intend to do an hour a day for five days a week, no matter how productive it feels, until it’s done. I may vary the plan as I go, but that’s it for now.

Advice?

I’m on Ducky… and I hate AIX

I finally got access to our new supercomputer, “ducky”, but it’s running AIX which is a total pain in the ass. Now I remember why UNIX kind of went away for a little while — all of these proprietary unixes, none of which are quite compatible with each other. I’m spoiled by Linux / BSD which are pretty much standard across the board, modulo some differences in filesystems.

ADDENDUM 2006-04-24 @ 11:11 CDT: Apparently some of my problems are because LONI (the Louisiana supercomputing network) is not allowed to carry Internet-1 traffic, only Internet-2. Probably because of the DoE, but they didn’t tell me exactly which party was concerned with it. *sigh*

Happiness is a Warm Cluster

The queue’s not too full on easter. The cluster has been very busy for the last few months, which makes it hard to set up new simulations because you can’t interactively test the job scripts. Today things were open enough that I could do so.
