Previously the tau package got the cxx and cc names from
os.path.basename(self.compiler.cxx), however if the path to the compiler
looks like "/usr/bin/g++-10.2.0" then tau's custom build system doesn't
recognize it. What we want instead is something that looks like "g++"
which is exactly what cxx_names[0] gives us. We already did this for
fortran, so I am not sure why we didn't do it here. Not doing this
causes a build failure when tau tries to use a polyfill (vector.h,
iostream.h) that doesn't seem to be packaged with tau.
Additionally, tau needs some help finding mpi include directories when
building with MPI, so we provide them. Unfortunately, we can't just say
that the compilers are mpicc and mpicxx in the previous fix to have
these things found automatically. This is because tau assumes we always
need the polyfill when the compilers are set to these values which again
causes a build failure.
The function we coded in Spack to load Python modules with arbitrary
names from a file seem to have issues with local imports. For
loading hooks though it is unnecessary to use such functions, since
we don't care to bind a custom name to a module nor we have to load
it from an unknown location.
This PR thus modifies spack.hook in the following ways:
- Use __import__ instead of spack.util.imp.load_source (this
addresses #20005)
- Sync module docstring with all the hooks we have
- Avoid using memoization in a module function
- Marked with a leading underscore all the names that are supposed
to stay local
Complete overhaul of the Legion package to better capture a more
up-to-date set of configuration options and variants. This update
adds additional flexibility and features that were requested by
users.
* Add version 21.03.0 and "stable" branch
* Remove all older numeric versions
* Add support for CUDA, Python, PAPI support and more
* Add maintainer
* This no longer uses the Spack `gasnet` package: it defaults to
using an embedded gasnet or can be pointed to an external
* MUMPS: Use GEMMT BLAS extension when possible.
This should improve the performance and is recommanded by the developers.
* MUMPS: Add a new "openmp" variant.
* MUMPS: Add a "blr_mt" variant.
This improves performance when using OpenMP but might not be compatible with all multithreaded BLAS.
