Linux64bit Numpy 1.6 test_nonsero_byteswap & test failed

Hi,
I am using MKL version 10.3 and Python 2.7.2 and compiled numpy1.6.1 using custom library method.
I ran numpy.test('full') and here is the output.

compiler options used "icc -O2 -g -fPIC -fp-model strict -openmp -xhost "

Couple of tests failed. Has anyone noticed similar problems. Is there a fix for these. These errors don't appear when numpy is compiled with gcc.

What libs did you link with? (32 bit or 64 bit)?

Hi,

I linked against 64bit libs. Here is how I generated my custom libs

In tools/builder directory

make libintel64 name=/home/user/libmkl_blas export=blas_example_list
make libintel64 name=/home/user/libmkl_cbals export=cblas_example_list
make libintel64 name=/home/user/libmkl_lapack export=lapack_example_list

Hi,

I have some questions related to used MKL libraries.

Quoting vyasd
make libintel64 name=/home/user/libmkl_blas export=blas_example_list
make libintel64 name=/home/user/libmkl_cbals export=cblas_example_list
make libintel64 name=/home/user/libmkl_lapack export=lapack_example_list


What exactly custom library was used to link with Numpy? Did you change example-lists?

Hi,
Here is my Numpy 1.6.1 site.cfg
[plain][mkl]
library_dirs = /home/vduggira:/cm/shared/apps/intel/composerxe/2011.5.220/compiler/lib/intel64:/cm/shared/apps/intel/composerxe/2011.5.220/mkl/lib/intel64
include_dirs = /cm/shared/apps/intel/composerxe/2011.5.220/mkl/include
mkl_libs = mkl_blas, mkl_cblas
lapack_libs = mkl_lapack
[/plain]
The example-lists haven't been edited in any way.
(This is numpy 1.6.1, the latest release. Not 1.6 as refered to in the subject line)
thanks,
Vyas

Hi,

I'd recommend to create the only one custom library (withall needed functions together: blas, cblas, lapack) to be used in site.cfg
