Title:
ローカル・アダプタの読み取り操作により操作の完了が確認されるまで操作の肯定応答を遅延させる方法
Document Type and Number:
Japanese Patent JP5735883
Kind Code:
B2
Abstract:
A request to perform an operation, such as a remote direct memory access (RDMA) write operation or a send operation that writes to memory, is sent from a sending input/output (I/O) adapter (e.g., an RDMA-capable adapter) to a receiving I/O adapter. The receiving I/O adapter receives the request and initiates performance of the operation, but delays sending an acknowledgment for the operation. The acknowledgment is delayed until the operation is complete (i.e., until the memory is updated and the data is visible to the remote processor), as determined by a read operation initiated and performed by the receiving I/O adapter transparent to the sending I/O adapter.
