Disclosed is an apparatus and method of processing input and output in a multi-kernel system. A method of processing input and output in a multi-kernel system according to the present disclosure includes: setting a shared memory between a first kernel on a main processor and a lightweight kernel on a parallel processor; setting a data transmission and reception channel between the first kernel on the main processor and the lightweight kernel on the parallel processor using the shared memory; providing, on the basis of the data transmission and reception channel, an input/output task that occurs in the lightweight kernel to the first kernel on the main processor; processing, by the first kernel on the main processor, an operation corresponding to the input/output task; and providing a result of the processing to the lightweight kernel.

A cloud service broker apparatus and method thereof are provided. The cloud service broker apparatus includes a controller configured to provide a brokerage service between a plurality of cloud service providers and a cloud service user by dividing a cloud service requested by the cloud service user into a plurality of cloud service segments and distributing each of the cloud service segments to each of the clouds.

Cloud service broker apparatus and method thereof

Scheduling threads in a system with many cores includes generating a thread map where a connection relationship between a plurality of threads is represented by a frequency of inter-process communication (IPC) between threads, generating a core map where a connection relationship between a plurality of cores is represented by a hop between cores, and respectively allocating the plurality of threads to the plurality of cores defined by the core map, based on a thread allocation policy defining a mapping rule between the thread map and the core map.

Method for scheduling threads in a many-core system based on a mapping rule between the thread map and core map

A computing system for virtualization-based resource management includes a plurality of physical machines, a plurality of virtual machines and a management virtual machine. The virtual machines are configured by virtualizing each of the plurality of physical machines. The management virtual machine is located at any one of the plurality physical machines. The management virtual machine monitors amounts of network resources utilized by the plurality of physical machines and time costs of the plurality of virtual machines, and performs a resource reallocation and a resource reclamation.

Virtualization-based resource management apparatus and method and computing system for virtualization-based resource management

Provided are a virtualization based high availability cluster system and a method for managing failures in a virtualization based high availability cluster system. The high availability cluster system includes a plurality of virtual nodes, and a plurality of physical nodes each including a message generator for generating a message denoting that the virtual nodes are in a normal state and transmitting the generated message to virtual nodes in a same physical node. One of the virtual nodes not included in a first physical node among the plurality of the physical nodes takes over resources related to a service if a failure is generated in one of virtual nodes included in the first physical node.

A hierarchical system configuration method and an integrated scheduling method for offering a multimedia streaming service on a two-level double cluster system are provided. The hierarchical system configuration method includes the steps of: determining whether one server node exists; if one server node exists, determining whether one virtual server node/specific network storing and merging block exists; and if one virtual server node/specific network storing and merging block exists, setting a system configuration mode for configuring a single virtual server node based multimedia streaming server system and determining a representative network address of a current system, wherein depending on a scale and a characteristic of the multimedia streaming service, a hierarchical multimedia streaming server system is configured into a single virtual server node based system, which is a minimum-scale, a mono-level single virtual cluster based system, which is a medium-scale, and a two-level double cluster based system, which is a maximum-scale.
