OpenJDK: JVM and Multicore CPUs

[Paul Hohensee - Java SE]

And in addition (I duplicated Steve's list)

src/share/vm/runtime/vm_version.*
src/cpu/<arch>/vm/vm_version_<arch>.*     where <arch> == sparc, i486, amd64

src/share/vm/runtime/os.*                           Look at numa*(), 
processor_count(), is_MP()
src/os/<os_family>/vm/os_<os_family>.*    where <os_family> == solaris, 
linux, win32
