We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
This PR corrects a problem with the opa-psm2 package. It was
installing headers into <prefix>/usr/include and libraries into
<prefix>/usr/lib instead of <prefix>/include and <prefix>/lib.
The extra level of usr/ subdirectories causes dependent packages
like libfabric to fail to build.
* Add version 11.2.68
* Add variant to disable AVX2 for older hardware
* Change the makefile so libraries and includes are not placed
under $PREFIX/usr
* Updated URL and homepage
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
