I've tried Runtime.getRuntime().availableProcessors() right now and it works
OK to me and reports "2". I have Prescott, 1CPU, 2 hyperthreads, WindowsXP.
JNIEXPORT jint JNICALL
Java_java_lang_VMExecutionEngine_getAvailableProcessors
(JNIEnv *, jclass)
{
return port_CPUs_number();
}
So if it's broken for you it's broken in Java too.

Hi, I am using port_CPUs_number() for GCv5 to get the processor
number, but my desktop returns one processor with it on Windows
although my processor is dual-core. (port_CPUs_number is defined in
port_sysinfo.h).
I think we need more general form of processor number retrieval API
that can return processor information including that of core and
hyperthreading.
How do you think?
Thanks,
