SpeedForce is a framework for distributed parallel computing. It is developed by using C++ programming language. It's simple, but powerful. It has dozens of instructions set which is very user-friendly. SpeedForce supports a variety of operating systems, like Linux (Ubuntu, Fedora, CentOS etc.), Windows Subsystem for Linux, Android and macOS. It also supports multiple users and multiple tasks.
Speedforce includes three modules: process management, information center, and task management. The process management is mainly used to start or kill processes. It's basically executed in the background. The information center provides the message notification of task submission, file transfer, task execution etc. The task management involves all management related to executable programs, including task execution, information feedback, and task monitoring. In addition, SpeedForce has a few more functions as well. For instance, initialization function could allow users to save significant time on deployment of SpeedForce. Speedforce also can easily add local users, as well as add users on other nodes remotely.

The remote initialization is performed by process management module. The sfroot need start in the background before remote initialization.
