mostly for use in the :mod:`compute` and :mod:`calculator` submodules.

"""


[docs]class CalculationError(Exception): """ Raised when a particular calculation fails, for non-fatal reasons. """
[docs]class MaxMemoryEstimateExceeded(Exception): """ Raised when a structure is estimated to exceed the max memory. """
[docs]class CriticalError(RuntimeError): """ Raise this when you don't want any more jobs to run because something uncorrectable has happened! Plays more nicely with multiprocessing than SystemExit. """
[docs]class InputError(RuntimeError): """ Raise this when there is an issue with the input files. """
[docs]class WalltimeError(RuntimeError): """ Raise this when you don't want any more jobs to run because they're about to exceed the max walltime. """
[docs]class NodeCollisionError(CalculationError): """ Dummy exception to raise when one node has tried to run a calculation that another node is performing. """
