Opteron code on Athlon64?

I have an application compiled (static, 64 bit, linux, PGI 5.2) on an Opteron system. Will I need to recompile to use the application to some Athlon64 based machines that we are planning to purchase?

Apologies if this is a ridiculously obvious question - I’m more of an end user of source package distributions than a developer.

Hi mekosmowski,

The instruction set for both chips are the same so you should have no issues running Operton optimized binary on an Athlon64.
