OpenGL Multipipe and OpenGL Multipipe SDK are very different. OpenGL Multipipe is an IRIX OS-level utility that allows an application to utilize multiple pipes, even though it was originally written for use with a single pipe. OpenGL Multipipe SDK is a programming interface for the development of “multipipe” applications, i.e., applications specifically designed to run in multipipe environments. Applications written with OpenGL Multipipe SDK will, in general, provide better multi-pipe scalability than single-pipe applications run transparently under the OpenGL Multipipe environment.
