Abstract: A redundant array of independent disks (RAID) storage system, includes a RAID master controller receiving a RAID request selectively communicating the RAID request to one of a plurality of storage devices, wherein first and second storage devices are directly connected outside a data communication path including the host among the storage devices. The first storage device determines upon receiving the RAID request whether distribution of a RAID sub-request to the second storage device is necessary, such that upon determining that the distribution of a RAID sub-request is necessary, the first RAID controller communicates the RAID sub-request to the second storage device via the direct network connection.

Abstract: A workload-aware distributed data processing apparatus and method for processing large data based on hardware acceleration are provided. The data processing apparatus includes a memory buffer including partitions. The data processing apparatus further includes a partition unit configured to distribute a mapping result to the partitions based on a partition proportion scheme. The data processing apparatus further includes a reduce node configured to receive content of a corresponding one of the partitions, and perform a reduction operation on the content to generate a reduce result.

Abstract: There is provided a method of interrupt scheduling. The method comprises: without allowing a target process woken up when an interrupt occurs to enter into a ready queue, directly comparing the priority of the woken-up target process with that of a current process performed before the occurrence of the interrupt, and executing a rescheduling in accordance with the compared result; and performing direct context switching with respect to the current process into the target process in accordance with whether or not the rescheduling is executed. Accordingly, in the method of interrupt scheduling, the preemption latency caused by the interrupt in the operating system of the computer system can be minimized by omitting the process of allowing the woken-up target process to enter into the ready queue and the process of selecting a process with the highest priority on the ready queue.
