Abstract: A method for performing memory operations is provided. One or more processors can determine that at least a portion of data stored in a cache memory of the one or more processors is to be stored in the main memory. One or more ranges of addresses of the main memory is determined that correspond to a plurality of cache lines in the cache memory. A set of cache lines corresponding to addresses in the one or more ranges of addresses is identified, so that data stored in the identified set can be stored in the main memory. For each cache line of the identified set having data that has been modified since that cache line was first loaded to the cache memory or since a previous store operation, data stored in that cache line is caused to be stored in the main memory.

Abstract translation: 提供了一种执行存储器操作的方法。 一个或多个处理器可以确定存储在一个或多个处理器的高速缓冲存储器中的数据的至少一部分将被存储在主存储器中。 确定与主存储器中的多个高速缓存行相对应的主存储器的一个或多个范围的地址。 识别与一个或多个地址范围中的地址对应的一组高速缓存行，使得存储在所识别的集合中的数据可以存储在主存储器中。 对于具有已经被修改的数据的已识别集合的每个高速缓存行，因为该高速缓存行首先被加载到高速缓存存储器中或者由于先前存储操作，存储在该高速缓存行中的数据被存储在主存储器中。

Abstract: A technique includes performing an update to a location of a non-volatile memory. The update is created by execution of at least one machine executable instruction of a plurality of machine executable instructions. The technique includes using a processor-based machine to selectively track the update to allow recovery of the execution to a given consistency point based at least in part on whether the machine executable instruction(s) creating the update are located within a synchronized section of the plurality of machine executable instructions.
