Hi,
Here is the MACHINE file I have used for amber7 and the GNU compilers:
<cut>
setenv MACHINE "linux/FreeBSD/Windows PC/Mac OSX"
setenv MACH Linux
setenv MACHINEFLAGS " "
setenv CPP "cpp -traditional "
setenv CC gcc
setenv SYSDIR Machines/standard
setenv LOAD "g77 -O2 -m64"
setenv LOADLIB "-lm"
setenv G77_COMPAT "-Wno-globals -fno-globals -ff90 -funix-intrinsics-hide"
setenv G77_OPT "-O2 -m64"
setenv L0 "g77 -c -g $G77_COMPAT"
setenv L1 "g77 -c $G77_OPT $G77_COMPAT"
setenv L2 "g77 -c $G77_OPT $G77_COMPAT"
setenv L3 "g77 -c $G77_OPT $G77_COMPAT"
setenv RANLIB ranlib
<cut>
Amber7 compiles and run pretty fast on the opteron when you have the chance
to get your hands on one. <SHAMELESS ADV> Thank you Alineos :) </ADV>
On one cpu it is comparable to one HP/Compaq/Digital ev67.1GHz.

Caveat, they were collected on an other opteron board and different cpu speed (240/1400MHz)
