摘要： Provided sets a limit of execution threads which can be simultaneously processes in an input/output system and compares the number of threads which are being currently executed with the limit of execution threads at the time of requesting an input/output event from a thread and manages a job of processing the input/output event in accordance with the comparison result. The apparatus for asynchronous input/output processing of a multi-thread according to the present invention restricts the number of threads which are processed in the asynchronous input/output system as many as the limit of execution threads to prevent deterioration of performance caused due to context switching overhead of the thread and efficiently manage the thread.

摘要： A network block device using a network asynchronous I/O method is provided. The network block device includes an asynchronous I/O interface for managing a plurality of socket connections; an request process unit for analyzing a request from a client through a socket, reading data from a disk and transmitting the read data to the client through the socket, and writing the data transmitted through the socket to the disk, through the asynchronous I/O interface; and a request processing unit for collecting a result event of processing an operation asynchronously requested by the request processing unit and informing the request processing unit of the collected result event, through the asynchronous I/O interface.

摘要： Disclosed herein are a resource manager node and a resource management method. The resource manager node includes a resource management unit, a resource policy management unit, a shared resource capability management unit, a shared resource status monitoring unit, and a shared resource allocation unit. The resource management unit performs an operation necessary for resource allocation when a resource allocation request is received. The resource policy management unit determines a resource allocation policy based on the characteristic of the task, and generates resource allocation information. The shared resource capability management unit manages the topology of nodes, information about the capabilities of resources, and resource association information. The shared resource status monitoring unit monitors and manages information about the status of each node and the use of allocated resources. The shared resource allocation unit sends a resource allocation request to at least one of the plurality of nodes.
