yes it does. Its the Woodcrest server chip http://www.intel.com/business/xeon/?cid=cim:ggl%7Cxeon_us_woodcrest%7Ck6913%7Cs which supports 32 and 64 bit operations. For example the new Intel Fortran compiler can grab more than 2 GB of memory (its a beta10 version). I think gcc 4.x can as well.
Nice. I didn't know this.
However, Tiger (OS X 10.4.x) is not completely 64 bit compliant - Leopard is supposed to be pretty darn close.
Is there a numpy flag I could try for compilation....
It's entirely compiler and system dependent. NumPy just uses the system malloc. If you can compile it so that the system malloc supports 64-bit then O.K. (but you will probably run into trouble unless Python is also compiled as a 64-bit application). From Robert's answer, I guess it is impossible under Tiger to compile with 64-bit support.
