Hi Gunnar, The only thing I fixed is related to recur (whose type was null and thus not unifiable with a primitive type). Concerning your fib2, I think the proble comes from the "then" being a long (1) and the else a double. Thus boxing is required to return either a long or double (well a Long a

If you are running pure arithmetic code over primitive arrays, and not doing allocation (so no seqs, higher order functions, etc.) then it's pretty straight forward to translate Clojure code to GPU code.
