Abstract: A method and an apparatus for processing to support scalability in a many-core environment are provided. The processing apparatus includes: a counter unit configured to include a global reference counter, at least one category reference counter configured to access the global reference counter, and at least one local reference counter configured to access the category reference counter; and a processor connected to the counter unit and configured to increase or decrease each reference counter. The at least one category reference counter has a hierarchical structure including at least one layer.

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.
