Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level 2-5 20 pt EUC 05 presentation2005-11-026 Multiprocessor support The Erlang runtime system of tomorrow:  1 OS process, configurable 1..n schedulers in separate threads runs all Erlang processes.  Can make use of multiple processors for the execution of Erlang processes.  Transparent for the Erlang programs. I.e. benefit from multi cpu system without need to change your Erlang code.
