Cray 1, Serial Number 1.

I used to sit on serial number 3 and eat lunch. It was at National Center for Atmospheric Research (NCAR) in Boulder, CO. It's now in Cheyenne, WY at a sister facility.
elucify@reddit
Huh, I just mentioned that machine in this sub a couple of weeks ago, because of the Cray X/MP in the hallway at NIH. So it's not in Boulder anymore, good to know.
roostie02@reddit
Working at NCAR is my dream job. What was your experience like there?
fsck_msdos@reddit
Long reply warning:
It was one of the best jobs, if not the best job I ever had. I was stoked to go to work each day. I lived in Boulder and Boulder wasn't as populated yet, so the commute was short. The commute involved driving up the mountainside, and it was normal to see elk, deer, bear, mountain lions, you name it, all on the daily commute. It was a great way to be greeted at the start of the day, and a reminder as to why climate sciences are so critical. The building is beautiful and the views are astounding. All of this is what made it very easy to get up for work daily.
At work, I was a contractor in the Scientific Computing Division (SCD), later renamed to Computational and Information Systems Laboratory (CISL) as a supercomputer operator.
I worked on several different supercomputer clusters from 2001-2006ish at NCAR Mesa Lab. The work hours flew by as I loved what I did, and most engineers and scientists seemed to love what they did, also. We all grumbled about pay, but such is the life of public scientists then and now.
During daily downtime, we would all just nerd out with people from other depts. The most basic real life example: "So what do those lights mean over there on that terminal/console?" and the person you are talking to, or who was talking to you, would do an information dump in the convo and you'd learn alllll kinds of new things, or teach others new things. We were mostly just all people who loved science and we got excited when others asked what we did.
I would regularly talk to the folks in the sun + space weather dept and could have done so for the rest of my life and been happy learning what they knew. I wanted to know what they did and how they did it, and they wanted to know the same for our dept. It was like this with any dept in so far as project and departmental NDAs and security clearances allowed.
My specific duty within the dept was to receive raw climatological and atmospheric data from field scientists and research facilities and educational institutions (and even tv meteorologists at times), format it into a computer language, and just feed the data into the clusters for computation. The data may be current or old, it just depended upon the project we were running for whomever. Climate models got spat out. It wasn't as tedious or boring as it sounds, due to the above coworkers, plus knowing all of that computational power could bow down to you with the right keystrokes (Crysis jokes were still hip and prevalent back then). You wanted the data to be fed in accurately, as any errors in computation were wasted energy (electricity) and time, both of which are precious when running clusters. So, we made sure no GIGO.
A particular work day that stands out was February 1, 2003. My shift was to start at 7 am local time, but I had arrived to work 15 mins early. At exactly 7 am, NCAR SCD got a call from NASA about Space Shuttle Columbia. We were to immediately put all clusters towards the goal of crunching all atmospheric and environmental data to aid in determining if the astronauts and shuttle could have survived, and where the craft would even have made terrestrial contact. It was a very solemn day, but we all knew what we were doing every moment of that day was critical.

Thank you so much for taking the time to write all this!! I really enjoyed reading it:) Sounds like it's a really special place to work.

Thanks for sharing !
Hatta00@reddit
Is it running?
Wells1632@reddit
HP still carts serial #1 around to various trade shows from time to time. I saw it at SC22 in Dallas.
PDP-8A@reddit
Is there a tour open to the public at the facility in Cheyenne?
fsck_msdos@reddit
Yes: https://www.cisl.ucar.edu/outreach/nwsc-tours
PDP-8A@reddit
Thanks! My first day on the job, 30 years ago, my coworkers took me to lunch at NCAR. What a view from the dining area!
SomePeopleCallMeJJ@reddit
I went to the Boulder NCAR visitor center back in 2016 for the sole reason of heading downstairs to sit on that Cray.
I didn't know they moved it, nor do I envy anyone who had to pull that job off. :-O
fsck_msdos@reddit
They moved it in January, 2021. It was publicly announced. I really wish I would have gone up there to watch the move, but alas, I did not.

fsck_msdos@reddit
I take it back. This NCAR press release makes it sound more like times moved in Jan 2022, so the Cray History link is off most likely by a year.

I worked up there for a few years in the Scientific Computing Division, which was renamed to the Computational and Informations System Lab. Basically, I was a supercomputer operator.

You can judge a computer by how posh the upholstery is...
skuterpikk@reddit
Still waiting for that limited edition Crimson Chesterfield Cray - CCCâą

Thereâs another one on the other side of the room that has velour cushions.
Josh-Kibosh@reddit
The Cray Supercomputer
ToBePacific@reddit
I was just there a couple months ago!
OddbitTwiddler@reddit
Worked at Motorola ASIC testing the chips for Cray. One time at lunch with the Cray Engineer we asked âSo what do you do next after designing the worldâs fastest computers?â He said âOur customers say, thatâs nice, we will take this one, but can you make one that is 20,000 times faster? Thatâs what we really need.â
ChrisC1234@reddit
There are two Crays in the photo. A Cray and a cray-cray.
kpfeifmobile@reddit (OP)
Guilty.
cristobaldelicia@reddit
that's three crays, ain't it?
nix206@reddit
Tres cray CrayâŠ
WingedGundark@reddit
Someone need to port Doom on this, because it is ported to absolutely everything. But afaik it doesnât exist for Cray-1.
cristobaldelicia@reddit
https://www.reddit.com/r/Doom/comments/khpzo3/john_carmack_on_twitter_afaik_nobody_ever_ported/ "The scalar CPU should be fast enough (in 1976!) to draw 320x200, but memory would be an issue because it wasn't byte addressable -- you could only load and store aligned 64 bit values, and a max of 1M elements would be a pinch."
Good news though, you can run Doom on a little over 16 billion soldier crabs! https://www.reddit.com/r/BrandNewSentence/comments/12c2m89/you_can_run_doom_on_16039018500_crabs/
WingedGundark@reddit
That is taken directly from the Carmackâs tweet and he didnât say that it canât be done, just that it is tricky. There are other âslightâ challenges too. You would need to find C compiler for Cray-1 or youâd need to write whole thing from scratch. Also, displaying the game on that thing would be quite tricky as it doesnât have a frame buffer. There was a third party manufactured one, Apple apparently used one, but those things are probably rare as hens teeth and possibly donât exist anymore. Running it on X would be a possibility, but does that exist nowadays either for Cray?
I think the main reason why no one at least have tried to port Doom on Cray-1 is the fact that actually functioning Cray-1s are extremely rare and not easily available and even if you could work on one, it would be extremely laborous task considering the complexity and limitations of the platform for such program.
cipher446@reddit
Look at the wiring! Also I love that you could sit on one.
TheySayItsADryHeat@reddit
But can it run Doom?
vamplovesfortune@reddit
Absolute legend!
Rotflmaocopter@reddit
Lol you cray dog
Atomic_RPM@reddit
very cool!
Laser_Krypton7000@reddit
As a non US citizen, where is it - CHM ?
kpfeifmobile@reddit (OP)
Itâs at the Chippewa Falls Museum of Science and Technology in Chippewa Falls, Wisconsin.
Laser_Krypton7000@reddit
Thanks đ
xampl9@reddit
The Deutsches Museum in Munich had one on display many years ago. It had brown upholstery đ
capacitorfluxing@reddit
Later, the X-MP would go on to power Jurassic Park. We all know how that turned outâŠ
macingpound@reddit
This was used 40 years ago for The Adventures of André and Wally-B, a CG short film made by Lucasfilm Computer Graphics Group, now known as Pixar.
kpfeifmobile@reddit (OP)
That was the Cray X-MP, which is also at the museum.X-MP
macingpound@reddit
Thx for the correction
kpfeifmobile@reddit (OP)
Hey that wasnât meant to be a shitty comment - it was just awesome that they were all there!
cristobaldelicia@reddit
I think you took it for sarcasm because of the avatar's angry eyebrows! ;D
macingpound@reddit
No worries
cristobaldelicia@reddit
Dave? What are you doing, Dave?
2raysdiver@reddit
I visited a friend at the U of Minn Computer Center in the '80s and sat on a Cray without knowing until he told us. Later on, I used to sky dive in Wisconsin with some folks who worked at Cray. Heard a lot of good stories about old man Cray...
shyouko@reddit
Strange that we don't need cylindrical interconnect now.
OldMork@reddit
different design, seymore cray believed in few central cpu's, opposite how they build today
Buckgrim@reddit
Only problem now is your going to be CRAY-ving more;-)
DivaMissZ@reddit
As long as you asked permission, and itâs consensual
thetacticalpanda@reddit
Is that the computer we see in Cosmo's office in Sneakers?
kpfeifmobile@reddit (OP)
I think the director based that computer on the Cray designs.
uid_0@reddit
It's hard to believe that the humble Raspberry Pi is around 4.5x faster.

It's been over 40 years since I last time saw this computer.
darkwater427@reddit
If only, if only.
Muta, Linus, et al. very well might have bought Cheyenne and I sooooo wish they did.
roz303@reddit
I sat on that very same machine at that very same place! Definitely much more comfy than the X-MP for sure. What did you think of their STAR-100?
AwezomePozzum9265@reddit
What museum is this?
AnxiousSpend@reddit
And in these days youngster sit on their laptop in the snow for the warm surface, wonder where they got that habit from :)
kpfeifmobile@reddit (OP)
Itâs an amazing little museum. Seeing the point to point wiring really was something.
Desmaad@reddit
That wire-wrapped backplane, oof!
DeepDayze@reddit
Imagine trying to find a single bad wire in that haystack...would drive any engineer nutso!
new2bay@reddit
Nah, easier to just scrap the whole machine and buy a new one đ
Hourslikeminutes47@reddit
"it's the blue wire dammit!"
"i'm cooorblind Rick!!"
Velocityg4@reddit
Just imagine if one of those wires was bad and your job is to find which one.
Hourslikeminutes47@reddit
its wire number sk8897yyhhdgggsggdvdby7266374
