Example of changing numba configuration for RDST
================================================

This example shows how to modify the numba options to change the behaviour of 
numba functions

.. GENERATED FROM PYTHON SOURCE LINES 11-20

Load the module and change the numba options
--------------------------------------------

The __init__.py file of convst contains four variable that will change how 
numba functions are compiled, please refer to the numba documentation for
the effect of each option. In a classic desktop use of convst, you should
not need to change any option. Issue have been known to occur on some HPC
cluster. By default, the variables are all defined as True, here we change
the value of __USE_NUMBA_CACHE__ and __USE_NUMBA_PARALLEL__ to False.

.. code-block:: default


    import convst

    convst.__USE_NUMBA_CACHE__= False
    convst.__USE_NUMBA_FASTMATH__ = True
    convst.__USE_NUMBA_NOGIL__ = True
    convst.__USE_NUMBA_PARALLEL__ = False


.. GENERATED FROM PYTHON SOURCE LINES 29-38

Run convst with the modified numba options
------------------------------------------

We can now use convst with these options, to check if the changes have been
taken into account, we can inspect a numba function argument.
!! THE MODIFICATION OF THE NUMBA CONFIGURATION MUST BE MADE BEFORE CALLING
ANY NUMBA FUNCTION, NUMBA TREAT GLOBAL VARIABLE AT CONSTANT AT COMPILE TIME
CHANGING THE VALUE OF THESE PARAMETER AFTER A FUNCTION IS COMPILED WILL NOT
CHANGE ITS BEHAVIOR.
