| * | | | | | | | ENH: Avoid memory peak when creating a MaskedArray with mask=True/False (#6732).Simon Conseil2015-11-261-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the `mask` parameter is set to True or False, create directly a `ndarray` of boolean instead of going inside `np.resize` which was causing of memory peak of ~15 times the size of the mask.

When printing a `MaskedArray`, the whole array is converted to the object dtype, whereas only a few values are printed to screen. So the approach here is to cut the array and keep only a subset that it used for the string conversion. This way the output should not change.

As a result of that fix, CBLAS detection failed for some Linux installations. The solution here is to add back the fallback detection but make it specific to non-windows platforms. Closes #6675.

This prevents the macro from being used like a function, e.g. one can't write like if ( !(arr = PyArray_FROM_OT( ... )) ) ... ... After removing the semicolon, the macro can be used like a C function.

Fix by storing all created tempdirs to delete at exit.

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.
