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: Disclosed herein are a data processing apparatus for pipeline execution acceleration and a method thereof. According to an exemplary embodiment of the present invention, the data processing apparatus for pipeline execution acceleration includes: a processor configured to sequentially execute a first application program and a second application program reading or writing a specific file; and a file system configured to complete a write for a file data for the specific file to a data block previously allocated from the first application program and provide the file data for the specific file to the second application program prior to executing a close call for the specific file from the first application program, when executing a read call for the specific file from the second application program.
