[R-sig-Debian] R 4.0 for ARM processors

[Patrice Kiener]

2 years ago at one Meetup in Paris, Marc Girondot, professor at 
University Paris-Saclay, presented his cluster built with 12 Odroid 
(equivalent to Rapsberry Pi). The stack was almost the same size than 
your picture as there was no fan and a narrower distance between each 
PCB card. There were many more cables. For a total cost of less than 
1000 € and an electrical consumption reduced by a factor of 7, he got 
the same calculation capabilities than the most expensive Intel i7 
processor. He used an Arch Linux distribution and Spark to distribute 
the load to every processor and then centralize the results to one 
processor equipped with a keyboard, a mouse, a screen and a hard disk.

 >> My RPi cluster sits on the file cabinet next to my desk, all four 
boards. Yes, you could argue that it's merely a toy.... but it's bigger 
and cheaper than the AWS box that currently hosts my web site, RStudio 
server, and Shiny server!

 > Got it. Missed the cluster part earlier and then confused myself 
looking for
arm64 16core machines. There aren't any :)

 > Neat :)  Very geek chic!
