Hi Jeff,

Sorry for answering late. These emails were hidden in another thread in my email client, so I didn't catch it until now.

The prebuild version of Open MPI was based on Windows 2008, which has InterlockedCompareExchange64 natively.

Windows XP doesn't have support of this function, so the prebuild Open MPI is not possible to be used under Windows XP. The only solution now is to build Open MPI
on your XP from source.


Regards,
Shiqing

Anyone (Shiqing perhaps) have any more thoughts on this problem?

Yeah, and I'm wrong too,
InterlockedCompareExchange64 is available on 32-bit.  I think this is one for Shiqing.

You could build OpenMPI yourself if you have VS2008.  It's pretty easy to do.

Damien -


I'm using the 32 bit version of OpenMPI.  I think the 64 refers to the size of integer that the function works on, not the operating system version.  I didn't have this problem with VS 2008, so I think they've changed something in VS 2010.  I just don't know how to fix it.

Jeff,

InterlockedCompareExchange64 is a 64-bit-only instruction.  Are you running XP 32-bit (I think you are b/c I don't think there was a XP64 SP3...).  You need the 32-bit OpenMPI version.  If you are running a 64-bit OS, but building a 32-bit executable, that instruction isn't available in 32-bit and you still need to link with 32-bit OpenMPI.
