+# Thursday, April 9th, 2026 Kokkos-Kernels Developer Meeting
+
+## Attendance
+
+Luc, Colleen, Yuuichi, Junchao, Daniel
+
+## Community
+
+## Testing
+
+### CI
+
+- Some progress on CUDA 13 CI: looking at using SNL GH machine
+- Added a CUDA debug build recently, might move it to a different machine
+- Would also like to have a Kokkos_ENABLE_COMPILE_AS_CMAKE_LANGUAGE build
+- One more for RDC (rellocatable device code) for good measure...
+
+### Nightly
+
+- [Kokkos Kernels](https://my.cdash.org/index.php?project=Kokkos+Kernels)' CDash
+
+## Documentation, Communication Structures
+
+- Will add PR to make tables for Sparse algorithms and show TPL support on the index page (Should be ready for 5.0!)
+- Will add PR to document gesv and svd
+- Need to add a PR to document sparse batched kernels
+- In general more explanations about TPL support would be nice: what type combination lead to TPL, how are we supporting analyze/compute phases, etc...
+
+## Release
+
+### 5.1.0
+
+- Is there any specific items you need/want ahead of the release?
+- regrets from 5.0.0
+  - rocSparse support for sparse triangular solve (5.1.0), Ichi working on it
+  - oneMKL support for sparse triangular solve as well (5.1.0) Luc starting
+- Lapack: GEQRF and UNMQR support [#2962](https://github.com/kokkos/kokkos-kernels/pull/2962) 
+- Sparse: ELLPACK format support in experimental mode
+- Support for Apple Accelerate in BLAS, LAPACK done [#2940](https://github.com/kokkos/kokkos-kernels/pull/2940)
+- Look at more ArmPL support in conjunction with CI work
+
+#### To Discuss / Resolve
+
+- Issue [#2622](https://github.com/kokkos/kokkos-kernels/issues/2622)
+  - Partially resolved, need to look at what triggers failures when enabling ARCH SKX
+
+- refactoring TeamVectorGEMM:
+  - PR [#2628](https://github.com/kokkos/kokkos-kernels/pull/2628)
+
+- trsv hermitian blocked algorithm
+  - PR [#2651](https://github.com/kokkos/kokkos-kernels/pull/2651), waiting for work on issue #2622 to be resolved before merging
+
+- refactoring TPL build system
+  - Remove logic that include TPL into the kokkos:: namespace and instead introduce them in kokkoskernels::
+
+- batched serial/team/teamvector rot
+  - PR [#2960](https://github.com/kokkos/kokkos-kernels/pull/2960)
+
+- Add Blas Concepts
+  - PR [#2944](https://github.com/kokkos/kokkos-kernels/pull/2944)
+
+#### Current issues:
