|\ \ \ \ \ \ | |/ / / / / |/| | | | | ENH: use prefetching for summation
| * | | | | ENH: use prefetching for summationJulian Taylor2015-11-163-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems the small blocksizes (128) messes up the hardware prefetcher which would usually be able to work fine on this iteration pattern. Fix this by using software prefetching. Improves performance for large sums by 15%-30%. Tested on core2duo, xeon E5-4620, i5-3470 and AMD phenom II X4. Prefers __builtin_prefetch as that, unlike SSE2 _mm_prefetch, also works on capable non-x86 cpus.

* | | | | | BUG: ma.make_mask should always return nomask for nomask argument.Charles Harris2015-11-112-4/+16
|/ / / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the mask argument was nomask, commit 8da9c71 changed the behavior to depend on shrink=True as well, resulting in array(False) false being returned when shrink=True, which in turn led to bugs because nomask is a singleton and is detected by `mask is nomask`. That dectection fails when nomask is replaced by array(False). Closes #6667.

| * | | | BUG, MAINT: Refactor ma.dot function and the corresponding method.Charles Harris2015-11-102-162/+221
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic implementation of ma.dot is moved from the method to the function and the function itself is moved from extras.py to core.py on account of import complications. The mask_rowcols function from extras is also moved to core.py as it is needed by dot. For backwards compatibility, both functions are still exported in extras.__all__ and can be imported from that module. They are not included in part of core.__all__. An out parameter is also added to ma.dot. This PR also closes #6611.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the _arraymethod class in ma.core with a function factory which returns class method wrappers around basic array methods. These methods are bound to the MaskedArray instance and are immutable. Previously _arraymethod was a class which would incorrectly operate on the MaskedArray object which last accessed the particular named function. closes #5247
* | | DEP: Remove FutureWarning from np.lib.split and go to future.Charles Harris2015-10-302-28/+13
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously an empty array resulting from split always had dimension 1-D. In Numpy 1.9 a FutureWarning was raised to notify users that it was planned to preserve the dimensions of empty arrays in a future numpy release. This removes the FutureWarning and implements preservation of dimensions. Note that there was a bug in numpy 1.9 and the dimensions of empty arrays was already preserved in some cases and no warning was issued. This PR fixes that inconsistency by preserving the dimensions in all cases rather than fixing the bug, as the dimension preserving behavior was already depended on by some users. See the discussion in gh-6575 about this change.

An attempt to use explicit imports led to errors, and because static code analysis in not sufficient to determine what functions need to be imported, it is safest to continue using `import *` pending a major refactoring of f2py. Closes #6563.
