Is the circular lock free buffer the answer?

Is the circular lock free buffer the answer?

Using a typical concurrent queue with reader/writer lock will work nicely but the rate of data coming in could be huge, so i wanted to reduce my locking overhead especially writer locks for the producers. I think a circular lock-free buffer is what I needed. Is circular lock-free buffer the answer?

Is there a lock free ring buffer in DPDK?

Although this is an old question, no one mentioned DPDK ‘s lockless ring buffer. It’s a high throughput ring buffer that supports multiple producers and multiple consumers. It also provides single consumer and single producer modes, and the ring buffer is wait-free in SPSC mode.

When do producers and consumers block the buffer?

The requirement that producers or consumers block if the buffer is empty or full suggests that you should use a normal locking data structure, with semaphores or condition variables to make the producers and consumers block until data is available.

What happens when a circular buffer is empty?

The free-list will give you pre-allocation and so obviate the (fiscally expensive) requirement for a lock-free allocator; when the free-list is empty, you replicate the behaviour of a circular buffer by instantly dequeuing an element from the queue and using that instead.

Is there lock free multiple producer queue in C + + 11?

I’m trying to implement a lock free multiple producer, multiple consumer queue in C++11. I’m doing this as a learning exercise, so I’m well aware that I could just use an existing open source implementation, but I’d really like to find out why my code doesn’t work. The data is stored in a ringbuffer, apparently it is a “bounded MPMC queue”.

Where is the data stored in a ringbuffer?

The data is stored in a ringbuffer, apparently it is a “bounded MPMC queue”. I’ve modelled it pretty closely to what I’ve read of Disruptor.
