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:: |

Granted, the term 'cluster' in the linux world is as open as the word |
| 23 |
'cocktail' at a social gathering; ymmv. |

Great link. But I typically avoid all things 'systemD' centric. (no |
| 32 |
discussion, just my preference). |
| 33 |
|
| 34 |
However I did find this stage 4: |

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

Not applicable. there are always a myriad of nuances with this approach, |
| 49 |
as I often stray into unique and exotic hardware extensions. Some run |
| 50 |
'clusters' on a collective of ity-bity IoT devices, cause they are |
| 51 |
fairly close together over Rf links. Folks at the companies that build |
| 52 |
chipsets, are very advanced in this venue. Most of it is DoD related and |
| 53 |
quite hush_hush. A billionaires club, so to accurately categorize. But |
| 54 |
there is no issue with gentoo folks finding their own pathways forward |
| 55 |
with clustering arm/micro devices. It is the future and even IoT |
| 56 |
security semantics will be based on each (I0T) nodes performance metrics |
| 57 |
as opposed to traditional security (bloated) codes. These IoT comm |
| 58 |
links, are like a predictable wave. Monitoring the wave, in the RF |
| 59 |
domain, shows where and when a small portion of (for example) field IoT |
| 60 |
sensors are stressed (under a heavier load than normal. So you do not |
| 61 |
have to strictly depend on specific codes and filters to detect anomalies. |
| 62 |
|
| 63 |
Monitor and matching of various domains yields startling results. BATM |
| 64 |
it is more of an art from than consistent technology. Surely the good |
| 65 |
folks of Gentoo will validate a pathway forward. |
| 66 |
|
| 67 |
What I have discovered is there are an enormous amount of very technical |
| 68 |
folks that routinely use gentoo, but keep it a secret. |

Gentoo, hacking and exotic hardware are more of an addiction than a |
| 75 |
source of joy. Be at peace. and |

THANKS for the link, |
