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: A method and apparatus for the distributed processing of a file are disclosed. The apparatus includes a shared data block selection unit, a modified data block selection unit, a first file distributed-processing unit, and a second file distributed-processing unit. The shared data block selection unit selects at least one first data block to remain without change after distributed processing of a file. The modified data block selection unit selects at least one second data block to be modified after the distributed processing of a file. The first file distributed-processing unit allows an inode after the distributed processing of a file to point to the first data blocks so that the first data block is shared before and after the distributed processing of a file. The second file distributed-processing unit allows the inode after the distributed processing of a file to point to at least one third data block.
Abstract translation: 公开了一种用于文件的分布式处理的方法和装置。 该装置包括共享数据块选择单元，修改数据块选择单元，第一文件分布处理单元和第二文件分布处理单元。 共享数据块选择单元在文件的分布式处理之后选择至少一个第一数据块来保持不变。 经修改的数据块选择单元在文件的分布式处理之后选择要修改的至少一个第二数据块。 第一文件分布处理单元允许文件的分布式处理之后的inode指向第一数据块，使得在文件的分布式处理之前和之后共享第一数据块。 第二文件分发处理单元允许文件的分布式处理后的inode指向至少一个第三数据块。

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: 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.

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 distributed system and a method for operating the distributed system. The method for operating a distributed system including a server and multiple clients includes acquiring, by a first client of the multiple clients, a lock on a shared resource using a first table of the server and a second table of the client, and releasing, by the first client, a lock on the shared resource using the first table and the second table, wherein the first table is a lock (DSLock) table for storing information about a distributed shared resource, and the second table is a data structure (DSLock node) table for a lock request.
