any #AWS #HPC folks familiar with the managed PCS service who can confirm that when using AWS PCS you can't configure Slurm to be aware of software licenses?
Adding license at CLI does not persist & API guide seems to confirm that "SlurmCustomSetting" does not support the "License" param ...

some cryoEM validation runs via cryosparc.com software integrated with #AWS parallelcluster HPC and using an FSX/Lustre parallel filesystem built from S3 input cryodata bucket via Lustre/S3 data repository associations. Can't do that on-prem!

The maverick hybrid truck was just to be for high MPG errand running and dump runs …. But I needed a rock bucket for the tractor and saw a sweet hydraulic dump trailer on dealer lot….
guess I tow stuff now. Swore I’d never own anything that could tow, hah!

@tgamblin.bsky.social -- thanks for the hint! Changing to curl for downloads was far easier than the other ideas I had

@techaro.lol users of spack just became collateral damage in the anti AI-scraping wars. All I'm trying to do is use spack.io to compile relion.readthedocs.io/en/release-5... for CryoEM analysis on an HPC cluster.
I know this is not your fault of course but wanted to point out an edge case

western Maine project continues. When this was a gravel pit they piled the good topsoil in one spot but it got overgrown w/ sumac & weeds.
Eventually we are gonna rent a big ass screening machine to separate out good dirt from rocks/trash and use the lovely soil for meadow planting & remediation.

Dirtwork on ~14 acres in western Maine. The excavator joins our 40hp tractor for running tools & implements. It’s gonna be used for trail/meadow building, woods/site cleanup, trenching, tree stump removal, firewood processing etc.
The tractor does most of what we need but is large and can’t dig.

Chinese excavators often ship with veg oil instead of hydraulic oil so first thing you do before playing with it is swap ALL the fluids and grease all the fittings. This thing has 26 separate grease couplers

No longer just a “tractor guy” as the Chinese mini excavator arrived. Midlife crisis takes many forms, heh.
This is the ECE CTX8012 Pro model. 1.5 ton diesel w/ all the features I wanted like swing boom, aux hydraulics, two speed tracking, expanding tracks & quick hitch

Speedrunning regaining my expired #aws certs. Got five in five days, although two were the foundational tier exams.
Gonna pause and study hard for the next series. I want Architect Professional, SysOps Professional and the Security Specialty certs next. AWS Professional exams are *hard* though

Annoyed that I let all my #AWS professional, associate and foundational certifications expire out of laziness so I just booked 4 remote proctored exams in 4 days.
Gonna clear the foundation/associate ones before taking the Professional exams later.

#unifi #ubnt nerd stack rebuilt at the commercial lot we are rehabbing. Paired a second UBB wireless radio bridge so we can put APs and cameras up on a third building. Radios links are *fast*.

I do a lot of #HPC clusters running #AWS #Parallelcluster for computational chemistry, specifically integrating it with the www.schrodinger.com small molecule & molecular dynamics tools.
Wallclock time to create a new on-demand GPU node & scale it in for a job was 4min 9sec. Fastest yet!
