This popped up on one of the Scala mailing lists today: Kilim [1] "Kilim is a message-passing framwork for Java that provides ultra-lightweight threads and facilities for fast, safe, zero-copy messaging between these threads.
It consists of a bytecode postprocessor (a "weaver"), a run time library with buffered mailboxes (multi-producer, single consumer queues) and a user-level scheduler and a type system that puts certain constraints on pointer aliasing within messages to ensure interference-freedom between threads." or, to really whet your appetite "Abstract. This paper demonstrates an architecture for suspending and resuming methods in Java using a restricted form of continuation passing style (CPS) transformation. It describes Kilim1, a toolkit to portably weave threads of control called Fibers, through Java code. The chief contributions of this paper are the set of design choices made for both space and time efficiency in getting one-shot continuations to work on the JVM (in some cases, 60x faster than competing approaches) and to address some tough issues traditionally passed over by others, such as handling of local subroutines and constructors. We are able to support hundreds of thousands of threads of control with switching times of the order of 3 to 4 μs on a low-powered laptop with Sun's JVM." In the one paper I've had time to read through, there are comparisons with JavaFlow, RIFE, PicoThreads, among others. There's code to download, a couple of papers linked on the page near the bottom, as well as a link to a talk presented at Google and available online. The paper I had time to read is very well-written to boot. Am bcc'ing the project's mailing list.
