A worker-scheduling method in a cloud-computing system and an apparatus for the same. The worker-scheduling method includes performing a first load-distribution operation of pre-creating template workers so as to process worker execution preparation loads in a distributed manner before a worker allocation request for function execution occurs, predicting a number of workers to be pre-allocated in consideration of variation in a worker allocation request period for each function, and performing a second load distribution operation of pre-allocating ready workers by performing worker upscaling on as many template workers as the number of workers to be pre-allocated.

Disclosed herein are an apparatus and method for setting the allocation rate of a parallel-computing accelerator. The method includes monitoring the utilization rate of the parallel-computing accelerator by an application and setting a start point, at which measurement of utilization data to be used for setting the allocation rate of the parallel-computing accelerator for the application is started, using the result of monitoring the utilization rate; setting an end point, at which the measurement of the utilization data is finished, based on the monitoring result; and setting the allocation rate of the parallel-computing accelerator using the utilization data measured during a time period from the start point to the end point.

Disclosed herein is a distributed file system using a torus network. The distributed file system includes multiple servers. The location of a master server may be determined to shorten the latency of data input/output. The location of the master server may be determined such that the distance between the master server and a node farthest away from the master server, among nodes, is minimized. When the location of the master server is determined, the characteristics of the torus network and the features of a propagation transmission scheme may be taken into consideration.
