Gaussian03 Binary vs. Source



 
Hi all,
 
I am about to buy Gaussian03 to run it on Linux. I wanted to buy the source in order to optimize it for each processor (I have both Athlon and Xeon machines), but Gaussian only supports PGF77 compiler. I wonder if someone out there could share sone information about:
 
- Is it possible to use g77 or Intel ifc to compile g03? Any success?
- Will the I suffer a significant performance penalty if I buy the Athlon (PII or higher) binary to run it also on the Xeons (in order to save money:-) ?
- Any problems with Mandrake, instead of the supported Red Hat and Suse?
 
Thank you very much
 
Pablo
