My python build binaries not really running as 64bit program in AMD Win2003r2x64 machine

My problem is

my python binaries not running as 64bits program on my amd64(Opteron 8214, 4 cpu) server.

The machine is a Dual-Core, so there are 8 core shown in taskmgr. It shown no "*32" in taskmgr(so it probably already in 64bits mode), but use only one core.

And I take same code(project) to compiled and executed on an Intel Xeon machine, it will use all of processor core.

So how do I fix this? Anyone have some other idea? I need to make it running 64bit to use mutli-core to get job done ASAP. It's a data parser, it took most of runtime to parsing data records(via regex) then insert into mssql db.

Any comment is welcome. I've been working on this many weeks.

Official & third-party packages I used listed here.

python-2.7.1.amd64.msi

pywin32-214.win-amd64-py2.7.exe

pyodbc-2.1.8.win-amd64-py2.7开发者_开发百科.exe

py2exe-0.6.9.win64-py2.7.amd64.exe

wxPython2.8-win64-unicode-2.8.11.0-py27.exe

build binary via GUI2exe-0.5.0.zip

On Windows Server 2003 Standard x64 Edition SP2 I ever built exactly same code(project) on Intel Xeon CPU machine(win2003x64 of course), And it was worked(work means no "*32" tailing on process name of taskmgr, and also use each of CPU/Core).

p.s. I cannot provide whole source code since it is a large project.

You might want to check out the subprocess and threading modules that come with the standard Python library with regards to your multi-core issue. As for the 64bit issue, are you sure you need the additional memory space? I've never had any issue with 32bit python.
