[gentoo-user] Raspberry Pi with 8GB

[james]

Gentoo Folks,

Has anyone ported gentoo to the newest Raspberry Pi
with 8 gig of ram?

https://www.admin-magazine.com/News/Raspberry-Pi-with-8GB-of-RAM-Now-Available

If so, I'd be curious as to your performance and using it as a 
workstation or mobile/laptop.

https://projects.raspberrypi.org/en/projects/raspberry-pi-setting-up

None of the usual gentoo embedded sites I have search list gentoo on 
this device.

All input is welcome. 8GB on a 64 bit arm low power (embedded) board, or 
a cluster of 4+ such boards is
of keen interest to my new, gentoo centric low power goals.


TIA,
James

This is the current state of the art, as far as I am aware.

Very cool link !

I'm going to try to buy 4; with the 8 gig of ram. I want to build a 
cluster out of them, for an accelerated portable gentoo system(s).

Any pointers to codes that create a cluster and run on 64Bit arm low 
power boards is welcome to post to this thread, or drop me a private note.


thx,
James

There is no such thing as cluster for arm. It's just daemons. You equip
each pi with the things it's going to need. You treat them as normal
computers.

If you don't know how to start... 
https://gentoo.osuosl.org/experimental/arm64/

there are actually some modern stage3 images. I suggest you google how
to emulate arm64 using qemu-static. google crossdev as well. There are
wonderful resources on the forums, some of which I participated in. 

Goo
d luck and happy hacking.

Huh. Well, I've run across dozens of projects, some as old as 2015. 
Sure, I have not 'dug into' the details, but they seem to be quite common::

https://magpi.raspberrypi.org/articles/build-a-raspberry-pi-cluster-computer

https://makezine.com/projects/build-a-compact-4-node-raspberry-pi-cluster/

https://projects.raspberrypi.org/en/projects/build-an-octapi/

https://www.hackster.io/aallan/a-4-node-raspberry-pi-cluster-e19273

Granted, the term 'cluster' in the linux world is as open as the word 
'cocktail' at a social gathering; ymmv.

Great link. But I typically avoid all things 'systemD' centric.  (no 
discussion, just my preference).

However I did find this stage 4:


stage4-arm64-minimal-20190115.tar.bz2

at https://gentoo.osuosl.org/experimental/arm64/old/

Any idea how chip specific this stage 4 for arm64 is?

Not applicable. there are always a myriad of nuances with this approach, 
as I often stray into unique and exotic hardware extensions. Some run 
'clusters' on a collective of ity-bity IoT devices, cause they are 
fairly close together over Rf links. Folks at the companies that build 
chipsets, are very advanced in this venue. Most of it is DoD related and 
quite hush_hush. A billionaires club, so to accurately categorize. But 
there is no issue with gentoo folks finding their own pathways forward 
with clustering arm/micro devices. It is the future and even IoT 
security semantics will be based on each (I0T) nodes performance metrics 
as opposed to traditional security (bloated) codes. These IoT comm 
links, are like a predictable wave. Monitoring the wave, in the RF 
domain, shows where and when a small portion of (for example) field IoT 
sensors are stressed (under a heavier load than normal. So you do not 
have to strictly depend on specific codes and filters to detect anomalies.

Monitor and matching of various domains yields startling results. BATM 
it is more of an art from than consistent technology. Surely the good 
folks of Gentoo will validate a pathway forward.

What I have discovered is there are an enormous amount of very technical 
folks that routinely use gentoo, but keep it a secret.

Gentoo, hacking and exotic hardware are more of an addiction than a 
source of joy. Be at peace. and

THANKS for the link,
