have a remote node as a member. Since we share remotes nodes and set
up tunnels, we cannot let two experiments have the same subnet
numbers. I use 10.0.0 nets and a DB table to allocate them with a
autoincrement field.

remote nodes so that we do not overlap between experiments.

This script grabs updated latency from Dave Andersen't database
of RON information, and sticks it into the widearea_recent table.

placing a "-1" anywhere in the latency or bandwidth matrices will result in
huge penalties when that connection is used in the mapping.

Also added neat (possibly novel?)
"mutation spike" which, when the standard deviation of the population gets
beneath a certain value, spikes the mutation rate from 1% to 50% for a generation,
thus keeping the deviation (and the population diversity) up.
Results from testing look promising.. in my "standard" 6-node mapping,
the solver finds the "best" solution in 95% of the runs.
(vs about 50% or less the old way.)

Also cleaned up the schema for both tables, so that they have proper
primary keys, etc.

Added "crossover rate" to improve population stability.
Changed termination behavior to stop if, after, 256 rounds,
no better solution has been found (changable with the -r switch.)

(smaller population, non-in-place child building,
 proper 'roulette' selection function, etc.)

*<name of pnode>
to
<name of vnode> <name of pnode>

This means that fixed vnodes may have unique names
(not just the name of the pnode they are fixed to.)

Added "-v -v" mode,
"-v" now just outputs progress without "friendly" prompts/output
or error analysis.

Fixed bizarre bug in mutation engine that was wedging the solver.
(Should also allow for expts with only 1 non-fixed node.)

Added check to skip solving altogether if there are 0 non-fixed nodes.
(this also handles the edge case of an input with no virtual nodes.)

Added check to exit with errorcode if there are more virtual nodes than
can be mapped.

When we put nodes into the reloadpending experiment, don't put
an entry into last_reserve - to be safe, delete such an entry
if it is there. This prevents the double-reload problem we've
been having, found by Leigh.

Whee!

- Halved penalty for overshooting bandwidth (undershooting remains the same.)
- Added penalty argument to -m for assessing multiplexing penalties.
- Made a few optimizations.

Small change for expts in TBOPSPID (emulab-ops for us): Instead of vname (which isn't usually defined), show when it was reserved to the expt. Great for checking on reloading nodes, hwdown nodes, etc.

if it fails, we exit gracefully from the node setup instead of
screwing stuff up even worse. Basically, I converted all close($TM) to
CLOSETMCC($TM) which does the proper checks and dies if error.
This is probably not ideal either, but not really sure what the ideal
solution is when tmcc fails.
