Yes, this needs a lot more work, I only picked a few low-hanging fruits |

does msvc complain using float to store information?

IIRC it complains in some tests when we pass in a double value.

does MSVC complain the descending index? or only type warning here
There was a problem hiding this comment.
This was a combination of a signed-unsigned warning and the fact that unsigned >= 0 is always true, so I needed to rewrite the condition to count upwards.

It's only defined in core/test/utils.hpp right now, but should we use the reduction_factor from there for the default value here?

Yes, but I would prefer to do that in another PR

Ginkgo release 1.4.0 The Ginkgo team is proud to announce the new Ginkgo minor release 1.4.0. This release brings most of the Ginkgo functionality to the Intel DPC++ ecosystem which enables Intel-GPU and CPU execution. The only Ginkgo features which have not been ported yet are some preconditioners. Ginkgo's mixed-precision support is greatly enhanced thanks to: 1. The new Accessor concept, which allows writing kernels featuring on-the-fly memory compression, among other features. The accessor can be used as header-only, see the [accessor BLAS benchmarks repository](https://github.com/ginkgo-project/accessor-BLAS/tree/develop) as a usage example. 2. All LinOps now transparently support mixed-precision execution. By default, this is done through a temporary copy which may have a performance impact but already allows mixed-precision research. Native mixed-precision ELL kernels are implemented which do not see this cost. The accessor is also leveraged in a new CB-GMRES solver which allows for performance improvements by compressing the Krylov basis vectors. Many other features have been added to Ginkgo, such as reordering support, a new IDR solver, Incomplete Cholesky preconditioner, matrix assembly support (only CPU for now), machine topology information, and more! Supported systems and requirements: + For all platforms, cmake 3.13+ + C++14 compliant compiler + Linux and MacOS + gcc: 5.3+, 6.3+, 7.3+, all versions after 8.1+ + clang: 3.9+ + Intel compiler: 2018+ + Apple LLVM: 8.0+ + CUDA module: CUDA 9.0+ + HIP module: ROCm 3.5+ + DPC++ module: Intel OneAPI 2021.3.

When I looked at a few of the warnings that the MSVC compiler generates, I realized that many of them point to potential overflows with 64bit indices, so I will use this PR to collect fixes for these issues.
