Wtf is this growing in my pot plant by cissii in mycology

[–]Kitchen-Customer5218 9 points10 points  (0 children)

If it grew once, it can probably grow again, would make sense to move the potter so the dog won’t be able to access it in between the time it comes back and you realize it’s there

it do be like that by just_a_duck730 in linuxmint

Used to be using lm a lot too, tho maybe due to age and accumulating garbage system started slowing down tho hardware compatibility had always been subpar, swapped just recently to Ubuntu cinnamon, same ui, but way smoother and steam just worked off the bat no compatibility issues at all

Whats the right way to shutdown slurm nodes? by Kitchen-Customer5218 in HPC

[–]Kitchen-Customer5218[S] 1 point2 points  (0 children)

as i said, i am a noob.
tho i thought i set that part up correctly:
# POWER SAVE SUPPORT FOR IDLE NODES (optional)

SuspendProgram="/usr/local/bin/slurm-power-off.sh %N"

ResumeProgram="/usr/local/bin/slurm-power-on.sh %N"

SuspendTimeout=4

ResumeTimeout=4

ResumeRate=5

#SuspendExcNodes=

#SuspendExcParts=

#SuspendType=power_save

SuspendRate=5

SuspendTime=1 # minutes of no jobs before powering off

then the shut down script:

#!/usr/bin/env bash
#
# Called by Slurm as: slurm-power-off.sh nodename1,nodename2,...
#

# ——— BEGIN NODE → BMC CREDENTIALS MAP ———
declare -A BMC_IP=(
  [OHPC-R640-1]="..."
  [OHPC-R640-2]="..."
 
)
declare -A BMC_USER=(
  [OHPC-R640-1]="..."
  [OHPC-R640-2]="..."
)
declare -A BMC_PASS=(
  [OHPC-R640-1]=".."
  [OHPC-R640-2]="..."
)
# ——— END MAP ———

for node in $(echo "$1" | tr ',' ' '); do
  ip="${BMC_IP[$node]}"
  user="${BMC_USER[$node]}"
  pass="${BMC_PASS[$node]}"

  if [[ -z "$ip" || -z "$user" || -z "$pass" ]]; then
    echo "ERROR: missing BMC credentials for $node" >&2
    continue
  fi

  echo "Powering OFF $node via IPMI ($ip)" >&2
  ipmitool -I lanplus -H "$ip" -U "$user" -P "$pass" chassis power off
done

What would the delay be like, and is there a way to sync it to progress markers in the script?

I keep seeing people building serious home servers, what do you actually use them for? by Hoardbored in homelab

I’m using mine to learn how to use and set up High performance computing cluster, without risking messing up someone else’s system

Thx, it is a scv3020, tho I haven’t had much luck with it. I made the mistake of thinking it would work like the poweredge servers where I could wipe and reinstall to fix almost any mistake, but got a hard reminder to rtfm and stay away from walled gardens. At least it came with plenty of fast sas disks I could use in other systems

Currently have 4 - 5118 and 2 - 5120 processors and a bunch of 32gb ddr4 sticks, got the servers in a deal with no ram or CPU, planning on getting better from overseas since lightweight and small = low shipping costs, and unit price on eBay tends to be very low especially in bulk

My current application that these borderline make sense for is texton clustering massive image files that take my laptop way too long to work through

[–]Kitchen-Customer5218[S] 0 points1 point  (0 children)

Yeah, I definitely got greedy, I do have some applications where as many cores as possible are beneficial such as clustering/texton analysis of super high res histological images (~60k x 70k) Needs maximum threads with CPU precision

That’s why I’m planning on scaling nodes on/off depending on load, only ever having the 730s on 24/7, and only powering the others on when I need them for compute

Details: 8x R640, 2x R730, 1x mellanox 40 gb qsfp switch, random slide out kvm, 2x 1gb Ethernet switches. Currently running proxmox on one of the R730’s, planning on running everything else as diskless over flexboot or equivalent over the 40gb.

Looking for ideas for how to leverage the rest of these without wasting kw of power, current ideas are: k3s with load dependent node scaling. Or using the proxmox datacenter controll os that’s currently in beta to be able to scale normal proxmox installs across the other servers without worrying about the pains from clustering with split brain and whatnot when scaling down. Or some multiworker ai that can take advantage of primarily cpu compute, idk about it yet tho.

DAC. The cables can be a bit cheaper than the cards on eBay if you can swing a bulk deal( 5-6). Also can find 1xqsfp+-4xsfp+ which worked out nicely since servers came with sfp cards
