Abstract: A critical section of machine-readable instructions is executed, the critical section including instructions to acquire and release at least one lock. While executing the critical section, information associated with a store instruction that stores data to a persistent memory is logged in a log. In response to an indication of a failure that caused execution of the section to fail to complete, recovery is performed by resuming, using the information in the log, execution of machine-readable instructions of the section starting from a most recent store instruction in the critical section, without executing machine-readable instructions of the critical section prior to the most recent store instruction.

Abstract: Examples herein involve storing registers in the event of a system failure. In examples herein, an association is made between a register and a location in persistent memory based on an execution of a process. Upon detection of the failure, the content of the register is stored to the persistent memory location based on the association.

Abstract: An example system includes a transient memory device, a persistent memory device, and a memory controller. The memory controller includes a whole cache flushing controller to cause all data in the transient memory device to be written to the persistent memory device and an access controller to identify location of most recent uncorrupted data in the persistent memory device.
