  • Committing transaction without first flushing processor cache to non-volatile memory when connected to UPS
    Patent number: 9772942
    Abstract: A computing system includes a processor that has a processor cache built-in, and a non-volatile memory, such as a non-volatile dual-inline memory module (NVDIMM), which is being used as system memory within the computing system. The processor processes a transaction. If the computing system is connected to an uninterruptible power supply (UPS) (and the UPS is connected to a mains power source that is currently providing power), the transaction is committed without first flushing the processor cache to the non-volatile memory. If the computing system is not connected to a UPS (and is connected to a mains power source that is currently providing power), the transaction is not committed until the processor cache has been flushed to the non-volatile memory.
