Abstract: Disclosed herein are an apparatus and method for managing a disaggregated memory based on memory access pattern recognition. The apparatus and method for managing a disaggregated memory based on memory access pattern recognition includes memory configured to store at least one program, and a processor configured to execute the program, wherein the program is configured to recognize a pattern of memory access to a disaggregated memory including a local memory and a remote memory of an application or a container and manage the disaggregated memory based on the recognized memory access pattern, and recognize memory access patterns for respective memory areas managed by at least one virtual memory area descriptor when the memory access pattern is recognized.

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 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 are an apparatus and method for accelerating file I/O offload for a unikernel. The method, performed by the apparatus and server for accelerating file I/O offload for the unikernel, includes; executing, by the apparatus, an application in the unikernal and calling, by the thread of the application, a file I/O function; generating, by the unikernal, a file I/O offload request using the file I/O function; transmitting, by the unikernal, the file I/O offload request to Linux of the server; receiving, by Linux, the file offload request from the thread of the unikernel and processing, by Linux, the file I/O offload request; transmitting, by Linux, a file FO offload result for the file I/O I/O offload request to the unikernel; and delivering the file I/O offload result to the thread of the application.

Abstract: Disclosed herein is an operating method of an apparatus for offloading file I/O of a unikernel based on Remote Direct Memory Access (RDMA). The operating method may include calling, by the application of the unikernel, a file I/O kernel function; generating, by the file I/O kernel function, file I/O information; transmitting, by the unikernel, the file I/O information to a Linux; configuring, by the Linux, a file I/O function using the file I/O information and calling the same; and transmitting, by the file I/O function, a file I/O request, corresponding to the file I/O information, to a file server.

Abstract: Methods for Joint Photographic Experts Group (JPEG) 2000 encoding and decoding based on a graphic processing unit (GPU) are provided. The method for JPEG2000 encoding based on a GPU includes receiving input image data from a central processing unit (CPU), encoding the image data, and transferring the encoded image data to the CPU.
