Abstract: A method of performing data management in a computing system comprises performing a checkpointing operation comprising storing checkpoint of the computing system, writing a plurality of nodes in a plurality of node blocks in a sequential write method after the checkpointing operation, each of the plurality of nodes comprising position information of a next node block, and during a subsequent recovery operation, selecting a node for recovery by scanning of the plurality of node blocks using the position information.

Abstract: A system includes: a nonvolatile memory; a memory controller configured to control the nonvolatile memory, the memory controller including a first buffer memory for temporarily storing write data to be written to the nonvolatile memory; and a second buffer memory having a lower operational speed and a higher memory capacity than the first buffer memory. The memory controller is configured to transmit the write data from the first buffer memory to the second buffer memory and to the nonvolatile memory, and to release an operational state of the first buffer memory after transmitting the write data from the first buffer memory to the second buffer memory and to the nonvolatile memory. Writing additional write data to the first buffer memory is prohibited prior to the release of the operational state of the first buffer memory, and is permitted after the release of the operational state of the first buffer memory.

Abstract: A scheduler controls execution in a memory of operation requests received in an input request set (IRS) by providing a corresponding output request set (ORS). The scheduler includes zone standby units having a one-to-one relationship with corresponding zones such that each zone standby unit stores an operation request. The scheduler also includes an output processing unit that determines a processing sequence for the operation requests stored in the zone standby units to provide the ORS.
