## What it is
Kokkos Core is a C++ programming model providing abstractions for parallel execution and memory management to write performance-portable applications across HPC platforms. It supports CUDA, HIP, SYCL, HPX, OpenMP, and C++ threads as backends and is a Linux Foundation / HPSF project.

## Use cases
- write c++ code that runs on both gpus and cpus without rewriting
- port a cuda application to amd gpus
- parallelize scientific simulation code for supercomputers
- manage multi-level memory hierarchies in hpc applications
- abstract away vendor-specific gpu programming models
- prepare code for exascale computing platforms

## When to choose
- you need a single c++ codebase targeting nvidia, amd, and intel gpus plus multicore cpus
- you are developing large-scale scientific or engineering simulation software
- you want a mature, production-level, community-supported performance portability layer

## When to avoid
- you target only a single gpu vendor and can use native toolkits like CUDA directly
- your project is small-scale and does not need hardware portability
- you need a language other than C++

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, gpu-computing, math, simulation, sdk
- domain: gpu-computing, performance, cross-platform, programming-languages
- platform: cpp, windows, cross-platform
