Abstract: Disclosed herein is a method for improving performance of a hypervisor in a memory disaggregation environment. The method includes allocating memory pages to a virtual machine in preset units, comparing the address range of the page frame to be returned with a preset page size, and removing an address space mapping for the page frame to be returned depending on a result of comparison with the preset page size. Removing the address space mapping comprises removing the address space mapping on the basis of contiguous page frames when the range of the page frame to be returned is equal to or greater than the preset page size.

Abstract: Disclosed herein is a method for memory management in a memory disaggregation environment. The method includes generating virtual memory based on multiple first memory devices, determining whether a condition for allocation acceleration is satisfied by the first memory devices, and allocating a memory page to the first memory devices based on whether the condition for allocation acceleration is satisfied.

Abstract: Disclosed herein are a method and apparatus for migrating a virtual machine in a memory-disaggregated environment. The method for migrating a virtual machine in a memory-disaggregated environment includes determining whether to migrate a virtual machine based on a number of accesses to a remote memory, establishing a migration policy for the virtual machine based on a remote memory access pattern, and determining a migration destination node based on the migration policy, wherein the migration policy includes a first migration policy corresponding to a case where the remote memory access pattern is sequential, and a second migration policy corresponding to a case where the remote memory access pattern is non-sequential.

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.
