Dear all,
 Is there any information for evaluation of results such as electronic
 energy from different kinds of computer? I want to know the derivation
 of results from different kinds of computer.
 For example, when Gaussian software is used, the same molecule's
 electronic energies calculated from different kinds of computer are:
 Intel Pentium III PC vs. Intel Pentium III PC cluster vs.
 Alphaworkstation vs. IBM RS/6000 SP Supercomputer vs. ... etc.
 Thank you for your attention.
 Best regards,
 Patrick
