Question 1

How to integrate libcds into a CMake project?

Accepted Answer

Use the provided CMake scripts from the build directory or install via vcpkg. Ensure consistent compiler flags, especially for DCAS support, to avoid linking issues, as noted in the README's build instructions.

Question 2

libcds vs Intel TBB concurrent containers?

Accepted Answer

libcds specializes in lock-free and fine-grained lock-based data structures with integrated safe memory reclamation, while TBB offers broader parallel patterns. libcds is better for pure concurrent container needs, but TBB has wider ecosystem support.

Question 3

Is libcds completely lock-free?

Accepted Answer

No, it includes both lock-free and fine-grained lock-based containers. For example, it has lock-free queues and maps, but also lock-based AVL trees, as detailed in the features list.

Question 4

How to use Hazard Pointers with libcds?

Accepted Answer

libcds integrates Hazard Pointers automatically for its containers; you typically don't need manual management. Refer to the doxygen documentation for advanced configuration and tuning options.

Question 5

What C++ versions does libcds support?

Accepted Answer

libcds 2.x requires C++11 and is compatible with GCC 4.8+, Clang 3.6+, Intel C++ 15+, and MS VC++ 2015 and above. It should work with newer standards like C++17 or C++20 if the compiler supports them.

Question 6

Are there performance benchmarks for libcds?

Accepted Answer

The README references academic papers for each algorithm, implying production-ready performance, but lacks specific benchmarks. Users may need to conduct their own tests for their use cases.
