Abstract: A memory access method and device are provided. A memory access method may include: identifying, when an access to a page of a remote memory occurs, a type of the access; allocating a sparse buffer when the access is a sparse write; storing data for the sparse write in the sparse buffer; storing an address for the sparse write as a key and the sparse buffer as a value in a buffer table; and updating an instruction pointer to point to a next instruction.

Abstract: Disclosed herein are a method and apparatus for verifying integrity in a memory-disaggregated environment. The method for verifying integrity in a memory-disaggregated environment includes receiving write data and multiple hash values generated based on write data from a remote memory, and verifying integrity of the write data based on the write data and the hash values, wherein verifying the integrity of the write data comprises selecting a hash value for the integrity verification based on an access latency of the remote memory.

Abstract: Disclosed herein is a method for managing memory in a memory disaggregation environment. The method includes handling a required subblock within a block more preferentially than an additional block in the event of a page fault and handling a page fault for the block in which the required subblock is preferentially processed.

Abstract: Disclosed herein are a method and apparatus for accelerating network transmission in a memory-disaggregated environment. The method for accelerating network transmission in a memory-disaggregated environment includes copying transmission data to a transmission buffer of the computing node, when a page fault occurs during copy of the transmission data, identifying a location at which the transmission data is stored, setting a node in which a largest amount of transmission data is stored as a transmission node, and sending a transmission command to the transmission node.

Abstract: Disclosed herein are an apparatus and method for accelerating genome sequence alignment. The method may include loading an essential index for a reference genome into memory, loading an additional index corresponding to the amount of available memory into memory, reading a target nucleotide sequence for which genome sequence alignment is to be performed, checking whether an exact match of the target nucleotide sequence is present in the reference genome based on the additional index, and generating a result of alignment of the target nucleotide sequence using the location of the exact match of the target nucleotide sequence in the reference genome when an exact match is found.

Abstract: An apparatus for memory integrated management in a cluster system including a plurality of physical nodes connected to each other by a network determines one of the plurality of physical nodes as a node to place a new virtual machine, allocates the first type of memory allocated to the one physical node to the new virtual machine as much as the memory capacity required by the new virtual machine, and distributes the second type of memory to a plurality of virtual machines running on the plurality of physical nodes by integrating and managing the second type of memory allocated to each of the plurality of physical nodes. In this case, the access speed of the second type of memory is faster than that of the first type of memory.

Abstract: Disclosed herein is an apparatus for managing disaggregated memory, which is located in a virtual machine in a physical node. The apparatus is configured to select, depending on the proportion of valid pages, direct transfer between remote memory units or indirect transfer via local memory for each of the memory pages of the source remote memory to be migrated, among at least one remote memory unit used by the virtual machine, to transfer the memory pages of the source remote memory to target remote memory based on the direct transfer or the indirect transfer, and to release the source remote memory.
