A render farm is a network of computers used to process large graphics that would take too long for one computer to handle. They are typically used for film special effects and other large models. Management programs are needed to coordinate the computers effectively.
A render farm is a network of computers that work together to process large graphics that would otherwise take much longer to render. While it can be used to render any graphics, a render farm is typically only used with film special effects and other graphics that are too large for a computer to process effectively. Each computer’s processor communicates with the processors of other computers, so everyone knows what the other computers are working on. Management programs are often needed to coordinate each computer to ensure they work effectively together on graphics.
Render farm networks are a large collection of computers that work together to render memory-intensive graphics. When someone creates an image or small animation, a single computer can often render that graphic quickly, but very large graphics can take hours, days, or even weeks. This slows down your graphics workflow and can cause your computer to crash while rendering. To get around this and make rendering much faster, many computers are used simultaneously to render graphics. While there are other types of farms, the render farm is used only for rendering.
Smaller graphics will not benefit from a render farm, and using one for small graphics can be expensive due to the large amount of energy required to power each computer. Because of this, only very large graphics go through a farm. These graphs are typically full-length, three-dimensional (3D) animations; computer aided special effects for films; and large models used in marketing. Each computer is also optimized for rendering, making farm work even faster.
During the rendering process, each computer’s processor will talk to the other computers in the render farm. Their communication isn’t very advanced and is usually limited to what each computer is uploading or downloading. This simplifies farm management, but is usually not enough to run the entire farm smoothly. Without some kind of management, two or more computers can render the same graphic, and since the image only needs to be rendered once, this wastes time and power.
To ensure that each computer only reproduces the graphics that need to be worked on, a management program is often used in conjunction with the network. The manager will check the workload and see which files still need to be rendered. Then he will distribute the files to the computers, making sure that each graphic is processed by only one computer.
