    • 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.
    • 公开了用于对等数据传输的技术,其中源设备从目标设备接收到读取数据字的请求。 源设备分别创建用于从目标设备读取多个数据字的第一部分和第二部分的第一和第二读取命令。 源设备向目标设备发送第一读取命令,并且在与第一读取命令相关联的第一读取操作完成之前,将第二读取命令发送到目标设备。 多个数据字的第一和第二部分分别存储在缓冲存储器的第一和第二部分中。 有利地,任意数量的多个读取操作可以在给定时间进行,而不使用多个对等存储器缓冲器。 改进了大数据块传输的性能,而不消耗其他对等GPU所需的对等内存缓冲区。

    • A spray nozzle assembly includes a pressure dependent variable spray orifice and an internal chamber which is at least partially bound by a flexibly deformable sidewall. At its distal end, the sidewall terminates at a distal face defining the spray orifice extending therethrough. A metering member extends distally from the internal chamber and through at least a portion of the spray orifice. As the pressure of a liquid supplied to the internal chamber by a liquid supply pathway varies, the flexibly deformable sidewall expands or contracts in response thereto. As the sidewall expands and contracts, the distal face moves relative to the metering member to change the effective size of the spray orifice.
    • 喷嘴组件包括由压力决定的可变喷射孔和至少部分地由柔性可变形的侧壁限定的内部室。 在其远端处,侧壁终止于限定延伸穿过其中的喷孔的远侧面。 计量构件从内部腔室向远侧延伸并且穿过喷射口的至少一部分。 当通过液体供应路径供应到内部室的液体的压力变化时,柔性可变形的侧壁响应于此而膨胀或收缩。 当侧壁膨胀和收缩时,远侧面相对于计量构件移动以改变喷孔的有效尺寸。
