摘要： Techniques are disclosed for peer-to-peer data transfers where a source device receives a request to read data words from a target device. The source device creates a first and second read command for reading a first portion and a second portion of a plurality of data words from the target device, respectively. The source device transmits the first read command to the target device, and, before a first read operation associated with the first read command is complete, transmits the second read command to the target device. The first and second portions of the plurality of data words are stored in a first and second portion a buffer memory, respectively. Advantageously, an arbitrary number of multiple read operations may be in progress at a given time without using multiple peer-to-peer memory buffers. Performance for large data block transfers is improved without consuming peer-to-peer memory buffers needed by other peer GPUs.

摘要： In an apparatus according to one embodiment of the present disclosure, a communications link comprises a first device and a second device communicating with each other via the communications link at a plurality of different speeds. However, prior to communicating via the communications link for the first time at a second speed, the first device and second device complete a first training cycle at the second speed. Further, during this first training cycle for the second speed, the first training cycle for the second speed will pause before the first training cycle at the second speed completes, and the first device and second device communicate at a first speed for a period of time before returning to the paused first training cycle at the second speed. When the paused first training cycle for the second speed continues, the first training cycle for the second speed will continue where it had paused.

摘要： Methods and apparatus for peer-to-peer data transfers in a computing environment provide configurable control over the number of outstanding read requests by one peer device to another. A requesting peer device includes a control register that stores a high-watermark value associated with requests to a target peer device. Each time a read request to the target peer device is generated, the number of such requests already outstanding is compared to the high-water mark. The request is blocked if the number of outstanding requests exceeds the high-water mark and remains blocked until such time as the number of outstanding requests no longer exceeds the high-water mark. Different high-water marks can be associated with different combinations of requesting and target devices.

摘要： A method and apparatus for providing peer-to-peer data transfer through an interconnecting fabric. The method and apparatus enable a first device to read and/or write data to/from a local memory of a second device by communicating read and write requests across the interconnectivity fabric. Such data transfer can be performed even when the communication protocol of the interconnectivity fabric does not permit such transfers.

摘要： Deadlocks are avoided by marking read requests issued by a parallel processor to system memory as “special.” Read completions associated with read requests marked as special are routed on virtual channel 1 of the PCIe bus. Data returning on virtual channel 1 cannot become stalled by write requests in virtual channel 0, thus avoiding a potential deadlock.

摘要： A computer system includes an integrated graphics subsystem and a graphics connector for attaching either an auxiliary graphics subsystem or a loopback card. A first bus connection communicates data from the computer system to the integrated graphics subsystem. With a loopback card in place, data travels from the integrated graphics subsystem back to the computer system via a second bus connection. When the auxiliary graphics subsystem is attached, the integrated graphics subsystem operates in a data forwarding mode. Data is communicated to the integrated graphics subsystem via the first bus connection. The integrated graphics subsystem then forwards data to the auxiliary graphics subsystem. A portion of the second bus connection communicates data from the auxiliary graphics subsystem back to the computer system. The auxiliary graphics subsystem communicates display information back to the integrated graphics subsystem, where it is used to control a display device.
