Abstract: Provided are a high-performance distributed storage apparatus and method. The high-performance distributed storage method includes receiving and storing file data by a chunk unit, outputting file data chunks stored in an input buffer and transmitting the file data chunks to data servers in parallel, additionally generating a new file storage requester to connect the new file storage requester to a new data server based on a data input speed of the input buffer and a data output speed at which data is output to the data server, re-setting a file data chunk output sequence for a plurality of file storage requesters including the new file storage requester, and applying a result of the re-setting to output and transmit the file data chunks stored in the input buffer to the data servers in parallel.

Abstract: Provided herein is a system for providing a virtual block device, which includes a logical block device configured to transmit and receive data to and from an external computer and to have logical block IDs, and a physical block device configured to include a cache area and a storage area for storing at least a part of the data and to have physical block IDs, wherein the cache area comprises a first memory cluster having first memory IDs, the storage area comprises a second memory cluster having second memory IDs and a third memory cluster having third memory IDs, and the physical block IDs include the first to third memory IDs. The system can simultaneously cope with both an application requiring a large capacity and an application requiring a short access time, using a single virtual block device provision system in which various storage devices are included.

Abstract: A cluster-based workflow system is provided which has the advantage of executing a workflow created by a non-IT researcher in a way that is suitable for computing resources in a cluster environment. The user can quickly analyze workflows using third-party applications, such as a large-scale bio data analysis workflow, a weather forecast data analysis workflow, or a customer relationship management (CRM) data analysis workflow, by using a large-scale computing cluster. In addition, third-party applications not optimized for a cluster environment can be automatically distributed and executed in parallel by preliminary analysis so that they run properly in the cluster environment.
