This used to be hacky code in blaslapack.py. I think I must have moved it into a function - instead of inline hacks in there. (and updated code as we saw breakages) Perhaps at some point it was also needed by superlu [since it has some blas equivalent - that should be skipping the optimization flags] - so it got moved into package.py. I guess we didn't do the alternative of identifying optimization flags used - and strip them out - as we don't know what they can be. Perhaps we could assume optimization flags are stored separately - and look for it [instead of assuming] - I don't know.. Satish On Tue, 30 Sep 2014, Barry Smith wrote:

And having a Windows and Not Windows functions for Opt flags in the API is disgraceful.

Matt,

Can all the �provider� stuff in package.py like

def getDefaultPrecision(self): '''The precision of the library''' if hasattr(self, 'precisionProvider'): if hasattr(self.precisionProvider, 'precision'): return self.precisionProvider.precision return self._defaultPrecision def setDefaultPrecision(self, defaultPrecision): '''The precision of the library''' self._defaultPrecision = defaultPrecision return defaultPrecision = property(getDefaultPrecision, setDefaultPrecision, doc = 'The precision of the library�)

be cleaned up/simplified/removed with the new BuildSystem model?

What was the original need for the provider stuff and is there still a need? If there is still a need can it be satisfied some other way. Is there every a need for a different provide for different packages? For example hypre gets one xxx provider and some other package gets a different xxxx provider.

The provider stuff is intended to support out-of-package ways to say something about the configuration. So we have an object that can come from anywhere. The stuff around it just access the object automatically, instead of making the user pull it out and reference it. I thought that was easier.

Do you want to just set a flag? I thought that was limiting, and duplicated information.

You can get rid of all this boilerplate code in newer version of Python. We have been outlawing newer versions. If we reopen that discussion, I vote for autoinstalling Python 2.7.

Thanks,

Matt
