[molpro-user] About the Athlon and P4 rpm package

In the download page of Molpro website, it says that "Opteron and xeon
systems should use the p4 rpm. Only use the i386 rpm if there is not a
tuned version available for your architecture."

However, I compare some calculations use the athlon and p4 rpm on my
Opteron system. I found that the athlon version rpm is about 5-10%
faster than the p4 version.

This is just for your information.
