# $Name: $ |

# Composed and tested by ce107 on ross/weddell (Opteron system) |
| 7 |
# Should work fine on EM64T and other AMD64 compatible Intel systems |
| 8 |
# a) Processor specific flags: |
| 9 |
# 1) for more speed on Core2 processors replace -xW with -xT |
| 10 |
# 2) for more speed on Pentium4 based EM64T processors replaces -xW with -xP |
| 11 |
# b) For more speed, provided your data size doesn't exceed 2GB you can |
| 12 |
# remove -fPIC which carries a performance penalty of 2-6%. |
| 13 |
# c) Provided that the libraries you link to are compiled with -fPIC this |
| 14 |
# optfile should work. |
| 15 |
# d) You can replace -fPIC with -mcmodel=medium which may perform faster |
| 16 |
# than -fPIC and still support data sizes over 2GB per process but all |
| 17 |
# the libraries you link to must be compiled with -fPIC or -mcmodel=medium |
| 18 |
# e) Changed from -O3 to -O2 to avoid buggy Intel v.10 compilers. Speed |
| 19 |
# impact appears to be minimal. |
| 20 |
# |
| 21 |
# DON'T FORGET to set environment variable MPI_INC_DIR to the include |
| 22 |
# directory of your MPI implementation |
| 23 |
|
| 24 |
#------- |
| 25 |
# run with OpenMP: needs to set environment var. OMP_NUM_THREADS |
| 26 |
# and generally, needs to increase the stack-size: |
| 27 |
# - sh,bash: |
| 28 |
# > export OMP_NUM_THREADS=2 |
| 29 |
# > export KMP_STACKSIZE=400m |
| 30 |
# - csh,tcsh: |
| 31 |
# > setenv OMP_NUM_THREADS 2 |
| 32 |
# > setenv KMP_STACKSIZE 400m |
| 33 |
# NOTE: need to set KMP_STACKSIZE in ~/.tcshrc (but curiously, works |
| 34 |
# without OMP_NUM_THREADS in ~/.tcshrc). |
