The link will be a bit slow, downloading the whole MEDIALIB for mirroring purposes.

Unless you count those geographically separate clusters with FDDI links :)
Come to think of it, I have like 3 of those cards and even some cables in London.

Use the main site, the mirror isn't ready.
Okay. I'll go grab it there. Was just seeing if I had it laying around so I could save on a download. ;)

Oh heck no. That sort of overhead's resultant latency would destroy
the performance of a cluster on all but the very fastest of machines.
Ah, right, I'm forgetting that clustering sends a lot of data.

Mmmm, true. Clustering is generally used for practical purposes and not my crazy experiments.

Clustering does not depend on DECnet or TCP/IP!
Really? I thought clustering over ethernet used DECnet.
Nope...SCS, which is Systems Communications Services if memory serves.
(is that right, Brian?) Completely unrelated to DECnet.
Brian (Hechinger) and I once discussed the possibility of implementing
a similar clustering system within NetBSD. I think just implementing
the SCS protocol itself would be a good start. I wonder if there's
enough documentation out there to do it.
What'd be really interesting is joining that to a VMS cluster. ;)

Nope, it's own LAN protocol.
Ah. That would explain why it's still functioning despite DECnet being hilariously broken on the simulated alpha. ;)
