[Beowulf] [EXTERNAL] Re: Build Recommendations - Private Cluster

And the OS-Link that connected the CPUs in Transputer land lives on as SpaceWire, which is a fairly popular high speed serial interconnect for spacecraft systems from 2 to 400 Mbps. (there is a faster version called SpaceFibre for both copper and optical that does multi Gbps).

    other machines such as Sun Enterprise 4000 and a 30 CPU Transputer
    Cluster. None of it runs 24/7 and not all of it is on at the same time,
    mainly because of the cost of power :-/

    I'm jealous. I recall recycling about 16 Transputers years ago
    because they were on an ISA interface card (systems I did not
    have anymore) Transputers were fun.

    And, I'm curious how many people have 42 inch racks at home.
    Mine is in a purpose built closet in my office. My neighbor
    is convinced I secretly work for the government. I also
    have all kinds of hardware and a big 3D printer in my office,
    which he says further confirms his assertion. My reply
    "I'm just a computer geek."
