Multiprocessing Services
In computing, Multiprocessing Services is a component of Classic Mac OS and Carbon allowing programs to perform work across multiple preemptively-scheduled threads of execution.
History
Multiprocessing Services was introduced in 1996 with the release of System 7.5.3.[1]
Multiprocessing Services 2.0, introduced in Mac OS 8.6,[2] is a backwards-compatible major release that increases the level of integration preemptive tasks have with the rest of the system.[3]
Multiprocessing Services 2.1, introduced in Mac OS 9,[1] adds support for devices with more than 1 GB of RAM.[4]
In Classic Mac OS
In Classic Mac OS, while applications using Multiprocessing Services have their threads preemptively scheduled, the application as a whole is still cooperatively scheduled with other running applications.[5]
In Mac OS X
In Mac OS X, Multiprocessing Services is implemented using POSIX threads.[6] Applications using Multiprocessing Services are preemptively scheduled with other tasks running on the system.[5]
