You could try references to his book by Haskell or Clojure folk rather than just the CMU pdf : e.g.,
http://www.amazon.com/Purely-Functional-Structures-Chris-Okasaki/dp/0521663504
There was a question here on SO at :
What is the benefit of purely functional data structure?
There is also Clojure area this :
https://github.com/viksit/clojure-datastructures
And there was this on SE :
https://cstheory.stackexchange.com/questions/1539/whats-new-in-purely-functional-data-structures-since-okasaki
Hope something there provides a basis for a search that bears results :-)
You may have to use an academic or biz ref search engine and you may want to look at poster sessions at a conf because search is not obvious here, e.g., Mercury can generate Erlang code ... so searching caching and locality with respect to performance in functional programming in some hardware area dealing with latency.
Canada'a National Research Council (NRC) had some work going on ... you could try a search of their pub's/notices/reports
But note: a search with
bigdata latency locality NRC 2012
gives rather different result from
bigdata functional latency locality NSF 2012
( and I would next drop the 2012 and try using the google search tool date range option for recent results)
