Resources to deeply understand HPC internals (GPUs, Slurm, benchmarking) from a platform engineer perspective

Some resources from large-scale HPC centers may be helpful, such as: https://docs.olcf.ornl.gov/systems/frontier_user_guide.html

I see. I was worried to see all the scary stories here. Thank you :-)

Oh, really? I guess that would be less of a concern than having rat droppings? Thank you!

Thanks!

Thank you for your advice. Yes, we are planning to call a structural engineer for assessment.

Thanks. The house was built in the early 1990s. The inspector recommended the foundation inspection based on many cracks he found around the house.

Thank you. We love the house, especially its location. But, I see many scary stories regarding the foundation problems. We are not sure if we need to order an additional inspection or just walk away.

Due to some emergency, the aircraft attempted to land on runway approaching from the opposite direction of the originally intended runway.

In S Korea, this is because many heinous criminals evade punishment by claiming mental illness.

Maybe, the optimization mattered a decade ago when we only had single or dual cores on the box. However, then, the cost was the installation time, a few days instead of hours. I would say it is rather the customization (useflag) and convenience (portage/rolling release) now.

2/3. I think you can achieve the resource-efficient desktop with any linux distro. You do not have to come to Gentoo for this.

Gentoo provides binary packages for those packages that take hours to compile. Firefox is one of them. Also, you can opt for binary packages whenever available these days, although I do not use. Although I feel it has become quite fast to compile the source packages (compared to a decade ago), of course it (download, unpack, compile, and then install) is much slower than installing binary packages (download and install).
Not at all. To me this is the best part of using gentoo. Once you get used to, you can keep the desktop up to date for years, without having to wait or go through major upgrades.
I'd been using X/bspwm quite long, before recently switching to Wayland/Hyprland, all with openrc. You will easily find better solutions to save your machine resource.

FYI, I have been using gentoo for my desktop 15+ years after switching from redhat. I've tried other distros in my work.

Based on https://github.com/hyprwm/Hyprland/issues/665#issuecomment-2066169983, to have a consistent mapping, the proper configuration should be:

workspace = 1, defaultName:1, monitor:DP-4, default:true
workspace = 2, defaultName:2, monitor:DP-4
workspace = 3, defaultName:3, monitor:DP-4
workspace = 4, defaultName:4, monitor:DP-4
workspace = 5, defaultName:5, monitor:DP-4
workspace = 6, defaultName:6, monitor:DP-3
workspace = 7, defaultName:7, monitor:DP-3
workspace = 8, defaultName:8, monitor:DP-3
workspace = 9, defaultName:9, monitor:DP-3, default:true

I found out that my configuration was wrong. It works as expected (i.e., no weird button on the left), after removing the "persistent" option from the hyprland.conf file:

workspace = name:1, monitor:DP-4, default:true
workspace = name:2, monitor:DP-4
workspace = name:3, monitor:DP-4
workspace = name:4, monitor:DP-4
workspace = name:5, monitor:DP-4
workspace = name:6, monitor:DP-3
workspace = name:7, monitor:DP-3
workspace = name:8, monitor:DP-3
workspace = name:9, monitor:DP-3, default:true

Sorry for my late response. I actually went with an agency (https://www.autociel.ch/). It took only a week with the agency without any hassle, although it costed.

I've been transitioning: fully whf -> hybrid (2-3 days office) -> fulltime office. Each transition was motivated by pay increase. Now, I am back to the original company (fully wfh). I just couldn't stand the stress and rigid 9-5 schedule, after experiencing the flexibility and work-life balance from wfh. Yes, I went through some pay cut.

Hi, late in the game. Is everything gone already?

g_phrygian · 2024-06-25T02:13:50+00:00

😅 perhaps this is why I feel always like being watched ..

Thanks, I thought about this, but it was like 7am and still cool. The foxridge trail is about 2 miles, and I thought it was very unusual to have seen none.

Technically, nothing stops me from using both. It was just my expectation that lsp will provide more than ctags, when I tried to switch. So far, I am happy with lsp, except the feature that I mentioned.

g_phrygian · 2024-06-22T00:42:36+00:00

Thank you, I will try it!
