JACK2 aka jackdmp is a C++ version of the JACK low-latency audio server for

multi-processor machines. It is a new implementation of the JACK server core

features that aims at removing some limitations of the JACK1 design. The

activation system has been changed for a data flow model and lock-free

programming techniques for graph access have been used to have a more dynamic

and robust system.

- uses a new client activation model, that allows simultaneous client

  execution (on a SMP machine) when parallel clients exist in the graph (client

  that have the same inputs). This activation model allows to better use

  available CPU on a smp machine, but also works on mono-processor machine.

- uses a lock-free way to access (read/write) the client graph, thus

  allowing connections/disconnection to be done without interrupting the audio

  stream. The result is that connections/disconnections are glitch-free.

- can work in two different modes at the server level:

  - *synchronous activation*: in a given cycle, the server waits for all

    clients to be finished (similar to normal jackd)

  - *asynchronous activation*: in a given cycle, the server does not wait for

    all clients to be finished and use output buffer computed the previous

    cycle.

    The audible result of this mode is that if a client is not activated

    during one cycle, other clients may still run and the resulting audio

    stream will still be produced (even if its partial in some way). This

    mode usually result in fewer (less audible) audio glitches in a loaded

    system.
