>(e.g. power4 vs power3)?

Yes. The server is 200MhzPowerPC3 CPU, the compute nodes are 333MhzPowerPC604e.
And the AIX system on server is AIX server2 3 4 00001946E800, the compute nodes are AIX warrior1 2 4 0034ADF9E200.
And I can only compile gromacs on the server node, because the compute nodes haven't the gcc compile.

Do you think that I can compile gromacs on the server and run the program on the compute node?

Could you tell me which correct architecture flags I should use in this suitations?
