The MT JVM

The Java programming language requires that MT programs be supported. All Java interpreters provide an MT programming environment. However, many of these interpreters support only uniprocessor multithreading, so Java program threads are executed only one at a time.

The Solaris JVM interpreter takes full advantage of multiprocessor systems by using the intrinsic Solaris multithread facilities. These allow multiple threads of a single process to be scheduled simultaneously onto multiple CPUs. An MT Java program run under the Solaris JVM will have a substantial increase in concurrency over the same program run on other platforms.
