Hi,
If I build Python 2.7.2 and numpy-1.9.1 and run the following script
import numpy c = numpy.ones((500000, 4)) mat = numpy.identity(4) r = numpy.dot(c, mat)
the evaluation of the 'dot' increases the memory by app. 35 MB.
If, in addition, I build numpy-1.9.1 with MKL support, and run the script, the evaluation of the 'dot' increases the memory by app. 450 MB.
Is the expected?
Best regards,
Mads
specs:
Ubuntu 12.04 ifort (IFORT) 14.0.1 2013100 gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)
No, but I don't know why that is happening with MKL. Can anyone else reproduce this?
