Abstract: 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.

Abstract: Disclosed herein is an apparatus and method for offloading parallel computation tasks. The apparatus inserts requests to execute multiple parallel thread groups into at least one parallel thread group queues, wherein when a preset order of priority exists the requests to execute is inserted into the at least one parallel thread group queues according to the preset order of priority, executes parallel threads of the parallel thread groups using a parallel thread group execution request entry extracted from the parallel thread group queue according to the order of priority, inserts an execution result into an execution result queue when execution of the parallel threads according to an execution sequence scheduled in execution startup routine code is terminated, and checks the execution termination state of the parallel thread groups by checking the execution result queue.

Abstract: 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.
