NumaArray
Implementation of three arrays which are transparently distributed onto multiple NUMA nodes using Silo, i.e., the i'th stripe of the array is allocated on NUMA node i. The arrays adpots and refines the NUMA array from Lorenz Hübschle-Schneider.
- An array, stored in a unique pointer.
- An array wrapped in a simple array class.
- An aligned array.
Additionally, transparent huge pages and a fallback for non-NUMA systems are used. The arrays require libnuma, Silo and Topo.
Usage
Add and link the NUMA array library.
# Add the repository to your subdirectories
add_subdirectory(your-path/numa_array/include)
# link library
target_link_libraries(your-application PRIVATE numa_array)Use the array in our code.
// Include the library
#include <numa_array.hpp>
// Create and use the array
size_t size = 1000000;
// Alignment of 16 bytes
size_t alignment = 16;
Numa::AlignedArray<T> aligned_arr(size, alignment);
Numa::Array<T> arr(size);
auto uptr_arr = Numa::make_numa_arr(size);
