Abstract: Systems and methods associated with computing cluster synchronization are disclosed. One example method includes periodically requesting timing values from a set of notes in a computing cluster. The method also includes receiving timing values from members of the set of nodes. The method also includes providing a synchronization value to members of the set of nodes. The synchronization value may be generated based on the timing values. Additionally, the synchronization value may be used to order events across the members.

Abstract: Simulator based detection of a violation of a coherency protocol in an incoherent shared memory system is disclosed. One example is a system including a simulator running on a first computing system, where the simulator simulates a second computing system that is a target for an application to be tested, and where the simulator includes a cache manager to monitor a state of a plurality of simulated caches in an incoherent memory system shared by a plurality of simulated processors, wherein the plurality of simulated processors simulate operations of a respective plurality of processors of the second computing system, and detect a violation of a coherency protocol in the shared memory system, and an alert generator to provide, via a computing device on the first computing system, an alert indicative of the violation.

Abstract: A memory region has logical partitions. Each logical partition has data packages. The memory region discontiguously stores the data packages of the logical partitions. A writing process can discontiguously generate the data packages of the logical partitions. A reading process can contiguously retrieve the data packages of a selected logical partition.

Abstract: Examples disclosed herein relate to a hierarchical file system. The hierarchical file system may include a first and a second virtual file referencing a stored data set. The first virtual file may include a set of first keys of a first level of specificity, with each key of the set of first keys including a record locator. The second virtual file may include a set of second keys referencing the data set and of a second level of specificity. The set of first keys within the first virtual file is searched in response to a query for data of the data set. A key from the set of second keys is accessed via the record locator from a key from the set of first keys where the data of the data set was not identified by the set of first keys.

Abstract: Examples include a system comprising a non-volatile memory, a cluster management interface, and a multi-node cluster. In some examples, the cluster management interface may monitor a system critical alert to determine if the system critical alert has been triggered. Based on the determination that it has been triggered, the cluster management interface may multicast a system failure notification. The multi-node cluster of the system has multiple nodes, each node connected to the non-volatile memory and having a processor and a processor cache. Each node of the multi-node cluster may determine if the system failure notification has been received and based on the determination that it has been received, each node may freeze execution of all processes on the process and flush the processor cache to the non-volatile memory.
