How to recompile openblas
-------------------------

Some notes about how to recompile packages from unstable:
`<http://wiki.debian.org/DebianUnstable>`_

Openblas with Sandybridge target support is available in the experimental
repository in debian. I recompiled it as follows::

	TARGET=SANDYBRIDGE USE_OPENMP=1 apt-get -b source openblas

By default, it uses pthreads, instead of openmp, which was interfering
with other use of openmp in my code. If we dont' specify the target, it
builds a lot of different architectures, and the right one gets selected
at runtime. Unfortunately it doesn't include Sandybridge yet.


Switch to new hy series
-----------------------

* add the new series in index_definitions.R
* in build_portfolio.R: replace hy23 by hy25
* in calibrate_tranches_MF.R, replace hy23 with hy25
* in load_cf.R replace hy23 with hy25

Update serie after default
--------------------------

Everything should be done right by running the script
``handle_default.py``. This is an example run after Sabine Oil
Default::

   python handle_default.py 103944 2015-06-23 15.875 100
