Abstract: A set of workload criteria is determined from a workload associated with a plurality of sources. The workload is divided among a set of workload groups according to the set of workload criteria and a first workload scheduler. A set of edge computing resources is assigned to each workload group within the set according to the set of workload criteria and the set of workload groups. A portion of the workload associated with a subset of the plurality of sources is handled by a first subset of edge computing resources and a second workload scheduler, where the subset of sources is associated with a first workload group. The handling includes balancing, by the second workload scheduler, the portion of the workload among the subset of sources. The handled workload is reported to a control center.

Abstract: A system and a method for scheduling a reduce task on nodes is disclosed. The various nodes in a cluster of nodes are bucketized into intermediate data items. A counter is created that provides a count of the intermediate data items that are placed into the each of the buckets for the node. This counter value is provided to a scheduler. From the counter information the scheduler is able to determine the cost of moving the intermediate data for the bucket to different ones of the nodes. Once the cost of moving the intermediate data is determined the scheduler is able to determine which of the nodes should perform the reduce task for that particular bucket. The scheduler minimizes the amount of shuffling of the intermediate data between the nodes for each of the buckets, by determining the lowest cost shuffle option for each of the buckets.

The present disclosure further provides a concentration measurement device.

Abstract: The embodiments of the present disclosure disclose a computer-implemented method, a system, and a computer program product for distributing data on multiple servers to multiple nodes in a cluster. In the method, each of M servers is instructed to divide data thereon into N data segments. M and N are integers greater than one. The M servers are instructed to send N×M data segments on the M servers to N nodes in a cluster concurrently. For each of the M servers, the N data segments are sent respectively to the N nodes. When any given node in the cluster receives a data piece of a data segment from a server of the M servers, the given node is instructed to transmit the received data piece to remaining nodes in the cluster other than the given node.
