Abstract: Aspects include receiving, at an operating system (OS) executing on a server, a notification that an error was detected during execution of a synchronous I/O operation issued by the OS to a persistent storage control unit (SCU). The notification is received from firmware executing on the server and it includes a command response block that includes error condition information about the error. The method can also include selecting, by the OS, a recovery operation for the synchronous I/O operation. The selecting is based on the error condition information about the error in the command response block. The selected recovery option is performed by the OS.

Abstract: Maintaining store order with high throughput in a distributed shared memory system. A request is received for a first ordered data store and a coherency check is initiated. A signal is sent that pipelining of a second ordered data store can be initiated. If a delay condition is encountered during the coherency check for the first ordered data store, rejection of the first ordered data store is signaled. If a delay condition is not encountered during the coherency check for the first ordered data store, a signal is sent indicating a readiness to continue pipelining of the second ordered data store.

Abstract: A method of avoiding a write collision in single port memory devices from two independent write operations is described. A first data object from a first write operation is divided into a first even sub-data object and first odd sub-data object. A second data object from a second write operation is divided into a second even sub-data object and a second odd sub-data object. The first even sub-data object is stored to a first single port memory device and the second odd sub-data object to a second single port memory device when the first write operation and the second write operation occur at the same time. The second even sub-data object is stored to the first single port memory device and the first odd sub-data object to the second single port memory device when the first write operation and the second write operation occur at the same time.
