# Composed and tested by ce107 on ross/weddell (Opteron system) |

|
# Should work fine on EM64T and other AMD64 compatible Intel systems |

|
# a) Processor specific flags: |
| 10 |
|
# 1) for more speed on Core2 processors replace -xW with -xT |
| 11 |
|
# 2) for more speed on Pentium4 based EM64T processors replaces -xW with -xP |
| 12 |
|
# b) For more speed, provided your data size doesn't exceed 2GB you can |
| 13 |
|
# remove -fPIC which carries a performance penalty of 2-6%. |
| 14 |
|
# c) Provided that the libraries you link to are compiled with -fPIC this |
| 15 |
|
# optfile should work. |
| 16 |
|
# d) You can replace -fPIC with -mcmodel=medium which may perform faster |
| 17 |
|
# than -fPIC and still support data sizes over 2GB per process but all |
| 18 |
|
# the libraries you link to must be compiled with -fPIC or -mcmodel=medium |
| 19 |
|
# e) Changed from -O3 to -O2 to avoid buggy Intel v.10 compilers. Speed |
| 20 |
|
# impact appears to be minimal. |
