Re: CCL:dual-core Opteron 275 performance

Hi,
 are these the values for the Gaussian provided binary version
 or pgroup compiled?
 In my own tests I saw a 2x+ performance advantage of the Xeon over the
 Opteron using a binary compiled with the Intel Fortran compiler on the
 Xeon and the Gaussian provided binary on the Opteron. Unfortunately
 I could not achieve a more fair comparison so far, since the Opteron
 binary would not run on an EM64T Xeon and I have been unable so far
 to compile G03 for the Opteron with the Intel compiler (I do not have
 a current version of the pgroup compiler).
 Regards,
 Peter
 P.S. Did you receive my fax & money for your AOMIX program
 (burger %x% chemie.uni-hamburg.de)? This is still my old account from
 Zuerich.
