Abstract: Disclosed herein are a cloud computing-based simulation apparatus and a method for operating the simulation apparatus. The method for operating a cloud computing-based simulation apparatus includes profiling a simulation in consideration of a simulation model and setup items that are requested by a user, when there is a history corresponding to results of the profiled simulation, calculating a resource configuration probability distribution for the simulation using the history, replicating the simulation environment to multiple simulation environments by selecting resource configurations in N simulation environments depending on the resource configuration probability distribution, where N is an integer of 2 or more, and simultaneously executing simulations in the multiple simulation environments.

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: Disclosed herein is a distributed file system using a torus network. The distributed file system may include multiple servers. The multiple servers are connected with each other through an n-dimensional torus network, and each of the multiple servers may be arranged along n-dimensional axes. Among the servers in the distributed file system, a server group of an (n−1)-dimensional torus network may be connected to a public network. Different loads of the distributed file system may be distributed based on the axes. Through the distribution, the processing performance of the distributed file system may be improved.

Abstract: Disclosed herein are a method and an apparatus for encoding/decoding an image. The image decoding method according to the present invention includes obtaining prediction information of a current block from a bitstream and, by performing prediction based on the prediction information, generating a prediction block of the current block. Herein, the prediction information includes split prediction information of the current block. The generating of the prediction block includes obtaining a reference sample from a neighboring block of the current block, applying an interpolation filter to the reference sample, and generating the prediction block by using the reference sample to which the interpolation filter is applied. The interpolation filter is determined based on the split prediction information of the current block.
