@johnregehr Found another tidbit about the PlayStation 3’s superoptimizer, if you’re interested https://news.ycombinator.com/item?id=21733922 …
Doesn’t sound fun :(

While the PS3's tools weren't too great at the beginning, they became *fantastic* as time progressed. The debugger is still my favorite of all time, the performance tools were great (IMO, preferable to PIX).

Did you ever do the thing with the Cell superoptimizer where you submitted code at early hours of the morning so the servers wouldn’t be as loaded and it would have more time to run and would produce better code? That’s one of my favorite stories.

I never played with the superoptimizer unfortunately. I can't say for certain if it was cloud hosted but if it was I could only imagine our legal department having a conniption if that's what it did. (

the only thing i saw that vaguely fits was an assembler that did some kind of brute force- but randomised search over instruction ordering & register allocation, and yes more compile time found faster runtime. people had favourite random seeds to pass it... wasnt cloud based tho

Interesting, thanks. I think I heard the story about the cloud one from Glenn Watson who worked at Sega at the time…
