From a software perspective, how do you guarantee that an engine's algorithm doesn't appropriate cpu/ram/cache resources in an unfair manner while running alongside the other engine?

well, i don't know how to guarantee it. i did monitor the engines in windows performance monitor--which watches cpu/ram/disk/etc--before running the tournament. they seemed to be switching on and off 100% when it was or wasn't their turn. try it.

Houdini is faster so it's better for quick analysis

After running this match and watching them grind away at similar positions in games 51-100, I can say I fully agree with the statement that it is faster. better, though? depends on the position.

most interesting? can't really say. depends on people's preferences, really. there were interesting *moments*, though. some really surprising moves. i can't remember any specific ones right now. i should make a web page for each win, so people can see the games. hmmm... i would love for people to analyze them, do an eco breakdown, etc.

yes. several. i am sorry i can't remember them. i think i will create a web page for each win, so people can watch the games w/o having to cut and paste the PGNs and view them themselves.
