Re: [Numpy-discussion] Building numpy with ATLAS

2016-07-18 Thread Shitikanth Kashyap 
As it turns out, I just had to run "python setup.py build --force" after 
changing my site.cfg file in order to recompile numpy/core/multiarray.so.

[Numpy-discussion] Building numpy with ATLAS

2016-07-18 Thread Shitikanth Kashyap 
Hey Everyone,

I am trying to build numpy-1.11.1 with ATLAS libraries. The build completes 
successfully, and 
I am able to use numpy, but there seems to be some problem with my config 
because 
numpy only ever uses one core, even when multiplying 5000x5000 matrices with 
numpy.dot.

My site.cfg is:

[default]
library_dirs = 
/u3/s4kashya/.local/atlas3.11/lib:/u3/s4kashya/.local/lib:/usr/local/lib:/usr/lib
include_dirs = 
/u3/s4kashya/.local/atlas3.11/include:/u3/s4kashya/.local/include:/usr/local/include:/usr/include

[atlas]
libraries = ptlapack, ptf77blas, ptcblas, atlas
library_dirs = /u3/s4kashya/.local/atlas3.11/lib
include_dirs = /u3/s4kashya/.local/atlas3.11/include


Output from numpy.__config__.show():

atlas_3_10_blas_threads_info:
   libraries = ['tatlas', 'ptlapack', 'ptf77blas', 'ptcblas', 'atlas']
   library_dirs = ['/u3/s4kashya/.local/atlas3.11/lib']
   define_macros = [('HAVE_CBLAS', None), ('NO_ATLAS_INFO', -1)]
   language = c
   include_dirs = ['/u3/s4kashya/.local/atlas3.11/include']
lapack_opt_info:
   libraries = ['tatlas', 'tatlas', 'tatlas', 'ptlapack', 'ptf77blas', 
'ptcblas', 'atlas']
   library_dirs = ['/u3/s4kashya/.local/atlas3.11/lib']
   define_macros = [('NO_ATLAS_INFO', -1)]
   language = f77
   include_dirs = ['/u3/s4kashya/.local/atlas3.11/include']
blas_opt_info:
   libraries = ['tatlas', 'ptlapack', 'ptf77blas', 'ptcblas', 'atlas']

   define_macros = [('HAVE_CBLAS', None), ('NO_ATLAS_INFO', -1)]

Any ideas what could be going wrong?
