Abstract: An apparatus for genome sequence alignment attempts a search for the hash tables to align a target nucleotide sequence, from a hash table having a large seed size to a hash table having a small seed size, and when there is at least one matched seed to the target nucleotide sequence on a hash table, aligns the target nucleotide sequence by using candidate positions from the hash table without further hash table searching.

Abstract: The preset specification provides a method of managing a disaggregated memory in a virtual system. Herein, the disaggregated memory managing method includes: detecting a memory access pattern in a virtual machine node based on an operation of a virtual machine; and performing a memory operation by using a memory block in consideration of the memory access pattern, wherein the memory access pattern is variably set based on a time at which the operation of the virtual machine is performed, and the memory block dynamically changes in size based on the memory access pattern.

Abstract: Disclosed is a method of managing a disaggregated memory. According to the present disclosure, the method includes: assigning at least one memory page to a local memory and a remote memory; checking a request for access to the memory page; checking whether a target performance ratio required in service is satisfied or not when the memory page requested to be accessed is assigned to the remote memory; predicting a size of the local memory on the basis of an LRU distance-based histogram when the target performance ratio is not satisfied; and reassigning the memory page requested to be accessed in consideration of the predicted size of the local 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.
