Java Threads and Multiple Processors

Java Threads and Multiple Processors

Question:
On a Windows NT box with multiple processors, will a multithreaded Java application get split between the processors automatically?

Answer:
This depends on the version and vendor of theJVM you are running. The Microsoft SDK for Javauses native NT threads to implement Java threads.These threads are scheduled by the operating system and will take advantage of multiple processors when available. This is also true of the Sun JDK for Windows NT.

The Sun JDK for Solaris similarly takes advantage of native Solaris threads which will utilize multiple processors when available.
