Install: brew install kokkos

About:
Kokkos is a C++ library that enables developers to write performance-portable code across diverse hardware architectures, including multi-core CPUs and GPUs. It provides abstractions for parallel execution and hierarchical memory management, allowing a single source code to target NVIDIA, AMD, and Intel accelerators. The ecosystem includes Kokkos Kernels, a library of high-performance linear algebra and graph algorithms.

Key Features:

Parallel execution policies for multi-core and GPU architectures
Multi-dimensional abstractions for memory layout and access
Built-in support for atomic operations and reduction patterns
Integration with the Kokkos Kernels math library

Use Cases:

Porting scientific HPC applications to heterogeneous clusters
Developing high-performance linear algebra kernels
Optimizing C++ code for GPU acceleration without vendor-specific code

Alternatives:

RAJA – Similar abstraction for loop parallelism, often integrated with the LLNL software stack.
std::execution (C++17/23) – Standard C++ library for parallel algorithms, though Kokkos offers more matured multi-GPU and memory management features.
