I don't know of any formal research, but in Clojure, where HAMTs are a fundamental part of the language, the philosophy is more oriented towards paying for things (such as thread safety) with memory and CPU first, benchmarking to find bottlenecks second, and if there are any bottlenecks, optimizing accordingly. It was written with this in mind, which is why it requires world-class VMs like the JVM, CLR, and V8/JSC/SpiderMonkey/etc. that can deal with the GC and (in many cases) make runtime optimizations. Also, I'm fairly certain synchronizing isn't an issue because there's nothing to synchronize on since the data structures are immutable. Am I understanding you correctly? |

No -- I'm referring to synchronization on the heap itself (think new()/delete()). Multiple threads allocating memory need to synchronize in order to avoid trampling on each other. You can't just get rid of synchronization entirely.
