From 9dcc93b5db91319b4f6b07066cc0b66e1ce73f2a Mon Sep 17 00:00:00 2001 From: Luc Berger-Vergiat Date: Wed, 21 May 2025 12:45:13 -0600 Subject: [PATCH 1/9] Kokkos Kernels revival: updating dot Some things have changed including various namespaces headers and signatures. With dot seems to compile correctly unfortunately something related to conjugate is failing at compile time. Let's fix that and try to run the dot_kk test.
