#2I was hoping for a list of projects this system has queued up. It’d be interesting to see where the priorities are for something so powerful.

I haven't been able to find a web-accessible version of their SLURM queue, nor could I find the allocations (compute amounts given to specific groups).
You can see a subset of the allocations here: https://www.ornl.gov/news/incite-program-awards-supercomputi...

You can infer a little from this [0] article:
ORNL and its partners continue to execute the bring-up of Frontier on schedule. Next steps include continued testing and validation of the system, which remains on track for final acceptance and early science access later in 2022 and open for full science at the beginning of 2023.
UT-Battelle manages ORNL for the Department of Energy’s Office of Science, the single largest supporter of basic research in the physical sciences in the United States. The Office of Science is working to address some of the most pressing challenges of our time. For more information, please visit energy.gov/science

#5The analogies used in this article were a bit weird.
Two things I’ve always wondered since I’m not an expert.
1. Obviously, applications must be written to run effectively to distribute the load across the supercomputer. I wonder how often this prevents useful things from being considered to run on the supercomputer.
2. It always seems like getting access to run anything on the supercomputer is very competitive or even artificially limited? A shame this isn’t open to more people. That much processing resources seems like it should go much further to be utilized for more things.

#6What's the documentation like for supercomputers? I.e. when a researcher gets approved to use a supercomputer, do they get lots of documentation explaining how to set up and run their program? I got the sense from a physicist buddy that a lot of experimental physics stuff is shared informally and never written down. Or maybe each field has a couple popular frameworks for running simulations, and the Frontier people just make sure that Frontier runs each framework well?

Google openmpi, mpirun, slurm. It's not complex.
It's like kubernetes but invented long ago before kubernetes

I feel like the name "supercomputer" is overhyped. It's just many normal x86 machines running Linux and connected with fast network.
Here in Finland I think you can use LUMI supercomputer for free. With a condition that the results should be publically available

#9I have a project on Frontier - happy to answer any questions!
Funny story about Bronson Messer (quoted in the article):
On my first trip to Oak Ridge we went on a tour of “The Machine”. Afterwards we were hanging out on the observation deck and got introduced to something like 10 people.
Everyone at Oak Ridge is just Tom, Bob, etc. No titles or any of that stuff - I’m not sure I’ve ever heard anyone refer to themselves or anyone else as “Doctor”.
Anyway, the guy to my right asks me a question about ML frameworks or something (don’t even remember it specifically). Then he says “Sorry, I’m sure that seems like a really basic question, I’m still learning this stuff. I’m a nuclear astrophysicist by training”.
Then someone yells out “AND a three-time Jeopardy champion”! Everyone laughs.
You guessed it, guy was Bronson.
Place is wild.
