LatencyTest

This is a C++ test task by Deltix Inc.

Rationale

Having a high-end multicore x86-64 machine actively running nothing but your application, You need to find the most efficient way (from the latency minimization perspective) to transfer simple data items (unsigned 32-bit integers) from one thread to another.

Content

This repository consists of three main parts:

• AbstractTransport - abstract class for a component capable to transfer data between two threads. We also provide a simple default implementation DefaultTransport.
• AbstractProfiler - abstract class for a component capable to measure latency of different transport implementations.
• Application - a simple benchmark runner, that performs data transmissions via AbstractTransport and calculates statistics using AbstractProfiler.

Your Task

1. Develop latency testing metodology and write it to YourProfiler implementation of AbstractProfiler class.
2. Write YourTransport implementation of AbstractTransport. Your class must outperform our simple implementation DefaultTransport at least on measurements made by YourProfiler.
3. Send us a link to a GitHub repository with your implementations.

Acceptance Criteria

1. You should not use any kind of message broker framework or profiling toolkit, instead you should implement this logic by yourself.
2. Your are allowed but not obligated to use synchronization primitives, collections and utility classes from any commonly used C++ libraries (STL, POSIX Threads, Qt, Boost).
3. From the other hand, we should be able to build your solution out-of-the-box using Make and Clang on CentOS 7 machine with nothing but compiler and standard headers installed.
