Abstract: A method of enforcing the ordering of read and write transactions for an adapter unit connected to a strongly-ordered bus. The adapter unit has a set of read buffers and write buffers. Initiator write transactions and target read completion transactions are performed on the bus in the original order in which the transactions are received. An initiator read transaction request is enqueued in the read buffer but selectively awaits the performance of one or more pending initiator write transactions in the write buffer before the read transaction request is presented to the bus. In this way, initiator write transactions on which the read transaction request depends and pending in the write buffer are retired to the bus before the initiator read transaction request is performed, thus assuring that the initiator read transaction request is not performed ahead of the initiator write transaction on which the read transaction request depends.

Abstract: Various embodiments of systems and methods for remotely configuring network memory are disclosed. One method embodiment, among others, comprises identifying a first device as having authority to control a memory device from a remote location, and writing start-up or reset parameters to memory of the memory device from the remote location, wherein the start-up or reset parameters are used to enable remote control of the memory device corresponding to remote direct memory access (RDMA) operations.

Abstract: In a system including multiple-slice processors and memories, a synchronization unit with race avoidance capability includes a delegated write engine that receives data and memory address information from the processors and writes data to the memory as a delegate for the processors.
