Dear CCLers,

we would like to buy a new computer for use with G03/linux.
have you got few benchs time results of  g03revC. test files ( test397 
is fine)
with 1/ g03 64bits compiled for opteron  (or/and  athlon 64)
        2/ g03 32 bits (compiled for pentium 4) on  the same opteron 
(or/and athlon 64)

does the 64bits compilation vs 32 bits improve performances ?

does the new intel xeon with EM 64  perform better  than  P4 (1MB in 
L2)  with G03 32 bits program ?
thanks for your help.
sincerely yours

Bertrand
