update Vector's AltiVec support
Issue #2381
resolved
Summit uses POWER9 processors, whose AltiVec SIMD engine accumulated bugs in Vectors. Pull request https://bitbucket.org/cactuscode/cactusutils/pull-requests/24/vectors-updates-for-altivec-and-knl/diff addresses these.
The pull request is from just before the Mayer release and has seen extensive discussion between @Erik Schnetter and myself as well as triggering creating a better test harness for Vectors (see #2380).
