摘要： Supporting multiple graphics processing units (GPUs) comprises a first path coupled to a north bridge device (or a root complex device) and a first GPU, which may include a portion of the first GPU's total communication lanes. A second communication path may be coupled to the north bridge device and a second GPU and may include a portion of the second GPU's total communication lanes. A third communication path may be coupled between the first and second GPUs directly or through one or more switches that can be configured for single or multiple GPU operations. The third communication path may include some or all of the remaining communication lanes for the first and second GPUs. As a nonlimiting example, the first and second GPUs may each utilize an 8-lane PCI express communication path with the north bridge device and an 8-lane PCI express communication path with each other.

摘要： An inkjet pen including an ink reservoir for storing ink and providing ink for jetting. A port, located on top of the ink reservoir, fluid-communicated with the ambient air, is used for adjusting the air pressure inside the reservoir. A valve, operated by a spring or a resilient element, normally seals the port, while occasionally opening the port to introduce air into the reservoir when the ink level is low and the underpressure rises. In other embodiments, an elastic bag is included in the reservoir that has an opening communicated with the ambient air through a second port formed on top of the reservoir. The elastic bag expands in response to the increasing underpressure generated in the reservoir when ink is being used. The bag expansion actuates the opening of the valve so as to regulate the underpressure.
