- [x] add `concretize.lp`, `spack.yaml`, etc. to licensed files
- [x] update all licensed files to say 2013-2021 using
`spack license update-copyright-year`
- [x] appease mypy with some additions to package.py that needed
for oneapi.py

|
|
"""Numexpr3 is a fast numerical expression evaluator for NumPy. With it,
|
|
expressions that operate on arrays (like "3*a+4*b") are accelerated and
|
|
use less memory than doing the same calculation in Python.
|
|
In addition, its multi-threaded capabilities can make use of all your
|
|
cores, which may accelerate computations, most specially if they are not
|
|
memory-bounded (e.g. those using transcendental functions).
|
|
Compared to NumExpr 2.6, functions have been re-written in a fashion such
|
|
that gcc can auto-vectorize them with SIMD instruction sets such as
|
|
SSE2 or AVX2, if your processor supports them. Use of a newer version of
|
|
gcc such as 5.4 is strongly recommended."""
