stdgpu::mutex_array< Block, Allocator >

Detailed Description

template<typename Block = mutex_default_type, typename Allocator = safe_device_allocator<Block>>
class stdgpu::mutex_array< Block, Allocator >

A class to model a mutex array on the GPU.

Template Parameters

Block	The internal bit block type
Allocator	The allocator type

Differences to std::mutex:

• Mutexes must be modeled as containers since threads have to call the exact same object
• Manual allocation and destruction of container required
• No guaranteed valid state
• Blocking lock is not supported
