HiperSockets SIGA light-sending without outbound queue

Performing logical partition (LPAR)-to-LPAR communication in a network computing environment. Read or write requests to different memory areas of a single computer memory are controlled by a storage control element, where the requests are issued by different multiple operating systems using a general network transfer format. A request is sent by a first operating system to said storage control element, where the request is executed with a processor instruction. A result of the request is received by the same or a second operating system. A modified processor instruction is sent to the storage control element, which implements an execution of the instruction synchronously performed to the sending of the instruction, without buffering the request of the instruction in a dedicated queue.
