The disclosure provides an approach for atomically executing computer instructions by a CPU of a computing device comprising non-volatile memory, the CPU configured to implement hardware transactional memory (HTM). The approach generally includes reading an instruction within a section of code designated as an HTM transaction, determining whether the instruction causes a data conflict with another thread, and copying cache lines from memory into a cache of the CPU. The approach further includes marking the copied cache lines as transactional, processing the instruction to create a persistent log within non-volatile memory, and unmarking the copied cache lines from transactional, to non-transactional.
