What is meant by a hardware thread. Is it always double the number of processor cores available? How to determine the number of hardware threads in an Intel Core2 Duo processor? Can it be determined through Java code?

You tell us. It’s not really an established term.
Ah, now it seems like you’re talking about hyperthreading where partial redundancies within a CPU core are used to “fake” an additional core.
You could try to find something in the system properties, but it’s not going to be standard (i.e. depends on the JVM and OS).
Personally, I’d just use a sensible default (4 or 8 threads – having a few too many is perferable to not using available cores) and make it configurable.
