The SDK/Open Server 12.5.1 release on the Opteron64 platform is primarily intended for 64-bit application development. However, Opteron64 architecture is compatible with Linux 32-bit shared libraries that are provided for backward compatibility. You can run existing 32-bit SDK or Open Server based applications on an Opteron64 platform. Development of 32-bit SDK or Open Server applications on Opteron64 requires a separate purchase of Linux 32-bit SDK or Open Server.
