6.5 0.0 L3 libcds VS moderngpumoderngpu is a productivity library for general-purpose computing on GPUs. It is a header-only C++ library written for CUDA. The unique value of the library is in its accelerated primitives for solving irregularly parallel problems. [FreeBSD & Copyright, Sean Baxter]

CDS C++ library
The Concurrent Data Structures (CDS) library is a collection of concurrent containers that don't require external (manual) synchronization for shared access, and safe memory reclamation (SMR) algorithms like Hazard Pointer and user-space RCU that is used as an epoch-based SMR.
CDS is mostly header-only template library. Only SMR core implementation is segregated to .so/.dll file.
The library contains the implementations of the following containers:
- lock-free stack with optional elimination support
- several algo for lock-free queue, including classic Michael & Scott algorithm and its derivatives, the flat combining queue, the segmented queue.
- several implementation of unordered set/map - lock-free and fine-grained lock-based
- flat-combining technique
- lock-free skip-list
- lock-free FeldmanHashMap/Set Multi-Level Array Hash with thread-safe bidirectional iterator support
- Bronson's et al algorithm for fine-grained lock-based AVL tree
Generally, each container has an intrusive and non-intrusive (STL-like) version belonging to cds::intrusive and cds::container namespace respectively.
Version 2.x of the library is written on C++11 and can be compiled by GCC 4.8+, clang 3.6+, Intel C++ 15+, and MS VC++ 14 (2015) and above

How to build
- *nix: [use CMake](build/cmake/readme.md)
- Windows: use MS Visual C++ 2017 project
Some parts of libcds may depend on DCAS (double-width compare-and-swap) atomic primitive if
the target architecture supports it. For x86, cmake build script enables
-mcx16 compiler flag that
switches DCAS support on. You may manually disable DCAS support with the following command line flags
in GCC/clang (for MS VC++ compiler DCAS is not supported):
-DCDS_DISABLE_128BIT_ATOMIC- for 64bit build
-DCDS_DISABLE_64BIT_ATOMIC- for 32bit build
All your projects AND libcds MUST be compiled with the same flags - either with DCAS support or without it.
**Building libcds -use vcpkg
You can download and install libcds using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git cd vcpkg ./bootstrap-vcpkg.sh ./vcpkg integrate install vcpkg install libcds
The libcds port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
