It even mentioned hobbyist clusters over the internet as a practical implementation. ;)
I'd be up for trying a cluster over the internet
Do you have the bandwidth for a high-performance one, or would we end up with a high-latency constantly-exploding one? ;)
My London site does about 1.5 Mbps up, 17 down, local (UK) ping of about 20-30 ms, up time at the moment is 57:13:59, but that's because I rebooted the router after some changes.
On a related note: How hard would it be to modify Johnny's bridge to carry LAN-over-IP traffic? Not sure I want to upgrade my boxes to 8.4...

I have lots of bandwidth here. But keep in mind, in clustering over
Ethernet, the "L" in "LAVC" stands for "Local". ;) I really don't see
it working well at all, but that's based on having done it locally, not
from actually trying it on a WAN.
I have access to systems with lots of bandwidth, they just implement a bit of MAC filtering and have limited IPs.

That's downright frightening. :) I may have to try that!

Basically, Brian has written some code on CHIMPY that produces output that I graph.
The grapher is more less ready - the end node scanner is still borked, waiting on Brian to fix it but it's Xmas and all :)
But it's very very close to mapping most of HECnet automagically.
One issue, can you use different colours? I have difficulty differentiating certain colours and I find it a little hard to see the differences between the lines.

Guys,
We're working on a network walker that will eventually produce a graph of HECnet.
We're basically doing a NCP SHOW KNOW CIRC, grabbing each area routing node and then recursively walking those.
Well it's a bit more complex than that, but that's the general idea :)
Once this is done, we do a NCP SHOW ADJ NODES to get the nodes in the area of each area router.
This is what we've come up with so far (the ADJ NODES code is under work, so if your node is missing, don't worry - mainly checking all the area routers are there):

That is VERY cool!
