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: In one example, disclosed are techniques to update application data files between open and sync and/or between two consecutive syncs using a syncv operation, file descriptors associated with each modified application data file and associated transaction records in a transaction log file.

Abstract translation: 在一个示例中，公开了使用syncv操作来更新打开和同步之间和/或在两个连续同步之间的应用程序数据文件的技术，与每个修改的应用程序数据文件相关联的文件描述符和事务日志文件中的关联事务记录。

Abstract: According to an example, versioned memory implementation may include comparing a global memory version to a block memory version. The global memory version may correspond to a plurality of memory blocks, and the block memory version may correspond to one of the plurality of memory blocks. A subblock-bit-vector (SBV) corresponding to a plurality of subblocks of the one of the plurality of memory blocks may be evaluated. Based on the comparison and the evaluation, a determination may be made as to which level in a cell of one of the plurality of subblocks of the one of the plurality of memory blocks checkpoint data is stored.
