I currently deal with large matrices.  I use the SciPy package of
Ubuntu 10.04.  The umfpack package is called libumfpack5.4.0.

The Python process uses approx. 6 GB of Memory and aborts.  The
traceback is

Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/scipy/sparse/linalg/dsolve/linsolve.py", line 88, in spsolve
    autoTranspose = True )
  File "/usr/lib/python2.6/dist-packages/scipy/sparse/linalg/dsolve/umfpack/umfpack.py", line 582, in linsolve
    self.numeric( mtx )
  File "/usr/lib/python2.6/dist-packages/scipy/sparse/linalg/dsolve/umfpack/umfpack.py", line 431, in numeric
RuntimeError: <function umfpack_di_numeric at 0x22fbe60> failed with UMFPACK_ERROR_out_of_memory

I suspect a 4 GB limit somewhere.  Can I do something about it?
