    摘要： A communication device management program that enables efficient use of memory space in receiving data using remote direct memory access (RDMA) techniques. The receiving node transmits a virtual ID corresponding to a receiving process to a remote sending node. A sending process in the sending node specifies this virtual ID when starting data transmission. If the receiving node has not reserved a memory area corresponding to that virtual ID, the sending node transmits a reservation request to the receiving node, which causes a data receiving memory area to be reserved for use by a communication device in the receiving node. In the sending node, the sending communication device begins sending transmission data in RDMA mode, from a memory area managed by the sending process to the reserved data receiving memory area. The receiving communication device directs incoming transmission data to a memory area managed by the receiving process.

    摘要翻译： 一种通信设备管理程序，其能够使用远程直接存储器访问（RDMA）技术有效地使用存储器空间来接收数据。 接收节点将与接收处理相对应的虚拟ID发送到远程发送节点。 发送节点的发送过程在开始数据传输时指定该虚拟ID。 如果接收节点没有预留与该虚拟ID相对应的存储区域，则发送节点向接收节点发送预约请求，这导致数据接收存储区域被保留以供在接收节点中的通信设备使用。 在发送节点中，发送通信装置从RDMA模式开始，从由发送处理的存储区域发送到保留数据接收存储区域的发送数据。 接收通信设备将传入的传输数据引导到由接收处理管理的存储区域。
