In the east there is a shark which is larger than all other fish. It changes into a bird whose wings are like clouds filling the sky. When this bird moves across the land, it brings a message from Corporate Headquarters. This message it drops into the midst of the programmers, like a seagull making its mark upon the beach. Then the bird mounts on the wind and, with the blue sky at its back, returns home.

The novice programmer stares in wonder at the bird, for he understands it not. The average programmer dreads the coming of the bird, for he fears its message. The master programmer continues to work at his terminal, for he does not know that the bird has come and gone.

Bouldering in Boulder

I don’t actually mind Boulder anymore because I have a friend there who climbs and skis, and they have the best climbing gym I’ve ever seen.

Unfortunately, I can’t get home on Friday night.. so it was either stay in Chicago, or stay in Boulder and get home even later. So I’m staying at the airport Hilton, which I’ve always wanted to do anyway for some reason. Note to onlookers: you can talk me into almost anything by pointing out that “it’s an adventure.”

(though I’m planning on taking a couple days off and driving to San Francisco – it will be good to see jbailey and auzure_skies again!)

Acquisition; Oktoberfest!

My employer is being bought by Sun Microsystems. Overall, I think this is a good thing. I know Sun hasn’t been the best Linux / Open Source player, but they have done a lot of good when you look at it. We’re going to be part of the systems group, whose mission is basically “Sell Sun hardware – we don’t care what it runs.” So we’re not going to be dropping Linux support any time soon, and the acquisition should free us up to work on Lustre more. I was in SFO about a month ago to meet with Sun (it was a secret at the time) and the environment there seems very positive towards CFS and what we’re doing.

In other news, I’m going to Oktoberfest from September 24-30. I should still be able to make tree climbing and baprime and mricon‘s reception. Surprisingly, a few cheap plane tickets were still available as of this morning, and I’ve found a couple of campgrounds that are a short train ride from the festival grounds.

Why this trip? Well, for the past few weeks, I’ve had a growing desire to “go somewhere, do something.” On Monday especially, I could hear aircraft fairly loudly from my office and I kept thinking “Why am I not on that flight? Where’s it going? Is that the direct flight to Munich?” Also, the deciding factor was yesterday, when I found out CFS is buying out our vacation (which I’ve been hoarding) so I have to use it or lose it :) Anyway, I like doing things at the last minute. This should be fun!

The things I do for money

I occasionally try to explain what I do for a living to people with varying degrees of success – so now I’d like to show you.

This is Jaguar.

It is the 10th most powerful supercomputer in the world and the most powerful open use machine (in other
words if you have a good enough reason to use it, you can.) It is an XT3 built by Cray. To give you an idea how fast it is, it last scored 43480 on the linpack benchmark. The laptop I’m writing this on would score about 1.

Jaguar and machines like it need storage – lots of it, and it has to be fast. I work on Lustre, which is a piece of software designed from the ground up as a scalable filesystem for Jaguar and machines like it.

The two racks in the foreground contain just over a petabyte of storage – that’s enough to hold the text from about a billion encyclopedias.


These are the disks and controllers for Jaguar. They were supplied by DDN, a partner of both Cray and my employer, and are
extremely fast.

geeks and disks

Our software brings all of this together into a useful filesystem that applications can use like any other filesystem (e.g. ext3, ntfs, vfat.) Well, like those, but faster.

So there you go..
