A user interface for a content presentation system is disclosed for displaying and manipulating graphical multimedia content for an audience while hiding operator-specific elements from the audience. The operator-specific elements are permitted to overlap the audience-viewable elements on the operator's display, allowing for optimal use of screen real estate particularly on smaller touch-based devices. The use of a multithreaded programming architecture is preferably employed to take advantage of multi-cored CPUs and GPUs, allowing the operator and audience displays to be governed by separate CPU cores or threads and therefore perform graphical manipulations with high efficiency.

A thread realization and dispatch method on data process operational platform relates to avoiding or reducing kernel thread switch, fully utilizing the processor efficiency and reducing system resources cost with the following stops: finishing design of thread controller, thread creation of thread bonding, starting operational thread activation, receiving items trigger transfer into operational state thread operation, finishing thread state switch, putting in order and operational array management thread dispatch and finishing clearance of thread data, releasing thread symbol, exit of thread of adjusting system thread numbers.

The invention provides a multi-thread parallel processing method based on a multi-thread programming and a message queue, belonging to the field of high-performance computation of a computer. The parallelization of traditional single-thread serial software is modified, and current modern multi-core CPU (Central Processing Unit) computation equipment, a pthread multi-thread parallel computing technology and a technology for realizing in-thread communication of the message queue are utilized. The method comprises the following steps of: in a single node, establishing three types of pthread threads including a reading thread, a computing thread and a writing thread, wherein the quantity of each type of the threads is flexible and configurable; exploring multi-buffering and establishing four queues for the in-thread communication; and allocating a computing task and managing a buffering space resource. The method is widely applied to the application field with multi-thread parallel processing requirements; a software developer is guided to carry out multi-thread modification on existing software so as to realize the optimization of the utilization of a system resource; and the hardware resource utilization rate is obviously improved, and the computation efficiency of software and the whole performance of the software are improved.
