In the case of the ACML compilation, I get:
0 [EMAIL PROTECTED] .../u0050015 $ python -c "import numpy;
numpy.show_config()"
atlas_threads_info:
libraries = ['lapack', 'acml', 'python2.4']
library_dirs = ['/apps/prod/python/2.4.3/lib']
language = f77
blas_opt_info:
libraries = ['acml', 'python2.4']
library_dirs = ['/apps/prod/python/2.4.3/lib']
define_macros = [('NO_ATLAS_INFO', 2)]
language = c
atlas_blas_threads_info:
libraries = ['acml', 'python2.4']
library_dirs = ['/apps/prod/python/2.4.3/lib']
language = c
lapack_opt_info:
libraries = ['lapack', 'acml', 'python2.4']
library_dirs = ['/apps/prod/python/2.4.3/lib']
define_macros = [('NO_ATLAS_INFO', 2)]
language = f77
lapack_mkl_info:
NOT AVAILABLE
blas_mkl_info:
NOT AVAILABLE
mkl_info:
NOT AVAILABLE
In the case of a more standard installation (blas/lapack/atlas) I guess
this might give some extra information, but as I understand these are just
the paths to the libraries that were used at compile time. If
show_config() in your case does not show your lapack dir, I am
afraid you are not using them as they were not found during compilation.
In order to use ACML I had to use a custom site.cfg (which basically
says what show_config() now reports), so I wanted some kind of extra
verification that the installation is fine.
My confusion actually comes from the fact that importing _dotblas in my
installation results in undefined references. Yet the timings of
numpy.dot seem ok, so 'some' optimized library is used, it is just not
clear which one.
