Thank you for the reply which is useful.
I also tried to Install numpy with intel mkl 9.1
I still used gfortran for numpy installation as intel mkl 9.1 supports gnu
I only uncomment these lines for site.cfg in site.cfg.example
library_dirs = /usr/physics/intel/mkl/lib/32
include_dirs = /usr/physics/intel/mkl/include
lapack_libs = mkl_lapack
then I tested the numpy with
>>a = numpy.random.randn(6000, 6000)
This time, only one cpu was used. Does it mean that our installed intel mkl
9.1 is not threaded?
I don't think so. We have used it for openMP parallelization for quite a
