A system includes first and second processors, first and second graphics processing units (GPUs), one or more peripheral devices, a switch matrix, and processor-readable memory. The switch matrix comprises programmable data paths between the processors, the GPUs, and the peripheral devices. Software encoded in the process-readable memory includes a first operating system (OS) executed by the first processor, a second OS executed by the second processor, a matrix scheduling engine, and a media interface switch (MIS) engine. The first OS boots faster than the second OS. The matrix scheduling engine runs on both OSs and configures the data paths in the switch matrix to couple the processors and the GPUs, and to couple the processors and the peripheral devices. The MIS engine runs on the operating systems, detects presence of the peripheral devices, and configures the data paths in the switch matrix to couple the processors and the peripheral devices.
