Just a few versions behind. Nothing major…

Yay! I still get to call Aurora the fastest mixed-precision system for a while! 🥰💕

Unpacked some new transceivers this afternoon. That’s 6.4Tbps one-handed!

Visualization of why I won’t be at SC24 (or many other conferences across a majority of states in the country), as rendered by erininthemorning.com - I expect the “light blue-grey” states will turn blood red when newly elected officials are sworn in come January as well. 15 states left for us.

I apparently know some science! ☺️

Felt cute so I posed with the fastest mixed-precision computer on the planet 💕

I silly-promised work I would dress “appropriately sciencey” for today’s awards ceremony. I forgot I had bought this blouse before the pandemic, but once I found it in the closet, I knew what had to be done. #BoldlyGo

Today, I was honored to receive the Board of Governors Award for Outstanding Safety Performance on behalf of the Aurora Supercomputer Install Team here at Argonne National Laboratory. Together, our team installed 300 tons of equipment and 300 miles of cabling with zero injuries. 💕

Mmm. Big tower.

Also joining the thread from 1998. Unfortunately, the majority of stuff from back then is long since lost or destroyed, but I do have one surviving blurry photo of my desk from the same time!

I only have a few pieces, but it was absolutely positively a requirement that I stop at NOTHING to acquire this piece in particular. 😉

New seasonal icon time! Swapping out the spring/summer flowers for the falling leaves and a PSL thanks to VaporGrowl @ FA. Now if only it wasn't 88F/31C outside today, I might actually be able to enjoy a hot latte...

I’m not really paying much attention to social media, but glancing back on today’s timeline, it seems someone’s making a stink about “being a fed”?

Pictured: actual fed (contractor) in actual federal building doing actual federal work on federal user facility’s biggest computer in the world:

I need to get back there! EBR-1 was closed for the season when I was at INL for work, so I haven’t made it inside yet. I‘ve touched X-10 down at ORNL though.

Show me a picture on your phone that has your energy that isn’t a selfie

What’s your sign?

I come with various warning labels…

Nooooooo… “Dearest” from InuYasha came on in the totally random mix on my iTunes and now I’m full of ALL THE FEELS 😭

Feeling cute, might saturate a 400G WAN later.

Three notes into 深い森 or Dearest and suddenly ALL THE FEELS 😭
