  "github_readme_excerpt": "# Concurrency Kit\n\nModern concurrency primitives and building blocks for high performance applications.\n\n### Continuous Integration\n\n[![Build Status](https://github.com/concurrencykit/ck/workflows/CI/badge.svg)](https://github.com/concurrencykit/ck/actions?query=workflow%3ACI+branch%3Amaster)\n\nCompilers tested in the past include gcc, clang, cygwin, icc, mingw32, mingw64\nand suncc across all supported architectures. All new architectures are\nrequired to pass the integration test and under-go extensive code review.\n\nContinuous integration is currently enabled for the following targets:\n * `darwin/clang/arm64`\n * `freebsd/clang/x86-64`\n * `linux/gcc/arm64`\n * `linux/gcc/x86-64`\n * `linux/clang/x86-64`\n\n### Compile and Build\n\n* Step 1.\n   `./configure`\n   For additional options try `./configure --help`\n\n* Step 2.\n   In order to compile regressions (requires POSIX threads) use\n   `make regressions`. In order to compile libck use `make all` or `make`.\n\n* Step 3.\n\tIn order to install use `make install`\n\tTo uninstall use `make uninstall`.\n\nSee http://concurrencykit.org/ for more information.\n\n### Supported Architectures\n\nConcurrency Kit supports any architecture using compiler built-ins as a\nfallback. There is usually a performance degradation associated with this.\n\nConcurrency Kit has specialized assembly for the following architectures:\n * `aarch64`\n * `arm`\n * `ppc`\n * `ppc64`\n * `riscv64`\n * `s390x`\n * `sparcv9+`\n * `x86`\n * `x86_64`\n\n### Features\n\n#### Concurrency Primitives\n\n##### ck_pr\n\nConcurrency primitives including architecture-specific ones. Provides wrappers\naround CAS in case of missing native support. This also provides support for\nRTM (transactional memory), pipeline control, read-for-ownership and more.\n\n##### ck_backoff\n\nA simple and efficient (minimal noise) backoff function.\n\n##### ck_cc\n\nAbstracted compiler builtins when writing efficient concurrent data structures.\n\n#### Safe Memory Reclamation\n\n##### ck_epoch\n\nA scalable safe memory reclamation mecha",
