Application Programming Interface for NumaAllocators.jl

NumaAllocators

Extends ArrayAllocators to allocate memory on specific NUMA nodes.

Examples

using NumaAllocators

Array{UInt8}(numa(0), 100)
Array{UInt8}(NumaAllocator(1), 100)

Main Interface

numa(node)

Create a NumaAllocator on NUMA node node. Short hand for NumaAllocator constructor.

Example

julia> using NumaAllocators

julia> Array{UInt8}(numa(0), 32, 32);

NumaAllocator(node)

Cross-platform NUMA allocator

Example

julia> using NumaAllocators

julia> Array{UInt8}(NumaAllocator(0), 32, 32);

current_numa_node()::Int

Returns the current NUMA node as an Int

highest_numa_node()::Int

Returns the highest NUMA node as an Int
