[SciPy-user] Installation on dual opteron ...

we are trying to install scipy on a dual opteron machine
(presently running SUSE Linux 10.0 OSS beta).
Because there is no fortran compiler installed (and it seems
there is none for that beta?), we started to compile
the relevant bits from scratch.
There are several problems, so before we start reporting them
in detail ;-), I would like to ask some general questions:
- I have read the thread started by Stephen Walton
and would like to know, if the patches
by Ravikiran Rajagopa
(including the c versions of d1mach.f, r1mach.f and i1mach.f,
have been applied to svn?
- Would you recommend to use
- gcc, Branch status 2005-09-13 (frozen for 4.0.2 release)
- or GCC 3.4.4 (released 2005-05-18)
instead of gcc 4.0.1?
(Would choosing gcc 3.4.4 have any negative impact on 64Bit
- And more generally: is there any progress concerning
Arrays >2GB with python/Numeric or numarray
(as mentioned by Perry Greenfield
The machine has 2x16 GB RAM and it would be nice
to be able to use them...
Many thanks in advance,
Arnd and Jan
Short notes on the installation:
- gcc 4.0.1 (via http://gcc.gnu.org/)
../gcc-4.0.1/configure --prefix=/scr/python --enable-shared \
--enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu \
- export CFLAGS=-fPIC
- Python 2.4.1
- ATLAS: atlas3.7.11.tar.bz2 (Linux_HAMMER64SSE3_2)
added: full Lapack version
- BLAS: gfortran -fno-second-underscore -O2 -fPIC -c *.f
- LAPACK: make.inc.LINUX,
In OPTS variable replace '-fno-f2c -O3' with '-O2 -fPIC'
./xconfig -F f "-fomit-frame-pointer -O -fno-second-underscore -fPIC" -b $BLAS
- 64 Bit
- Posix threads
- don't stop
- use express setup? [y]:
- Enter f77 compiler [g77]: gfortran
Enter F77 Flags [-fomit-frame-pointer -O -m64]:
- Tune the Level 1 BLAS? [y]:
One Problem is that the tests
make sanity_test arch=Linux_HAMMER64SSE3_2
make ptsanity_test arch=Linux_HAMMER64SSE3_2
