I give you, one access to our computer. I am not in my office these two
following days but you can contact me since monday. If you have a system
problem, you can send a mail to Bruno.Bzeznik at imag.fr

1. We have two versions of python installed to test scipy installation:
* *one compiled with gcc* (usr/local/stow/Python2.4.4)
* t*he other with the intel compiler* "icc"
(usr/local/stow/Python2.4.4_INTEL)
You have acces on these two directories.
2. I put in your *.bashrc the environment to use the Intel compilers *
3. The *scsl library *(scientific library optimized on our cluster with intel compilers) is in */usr/lib (compiled with Intel Fortran compiler)
*(On Itanium, the install procedure of ATLAS want to use Intel compilers, we can forced it to use Gnu compilers but we obtain bad optimizations)*
*
4. I attached on my mail the file *'site.cfg*' used to install scipy and numpy
4. I attached on my mail a file named *"whatWeHaveDone.txt" *in which I give you again what we have done to install numpy and scipy.
remarks: It seem that it's a bug in the part of program which extract
the intel version compiler. *An additional test is made in
numpy/distutils/command/build_ext.py to test this version *(ifort -V),
there is no version test in numpy/distutils/command/build_clib.py.
I tried to change this test in
/usr/local/stow/Python-2.4.4/lib/python2.4/site-packages/numpy/distutils/fcompiler/intel.py...but
it doesn't run.
thanks for your help
