This dataset is generated randomly for the budget-constrained Dynamic Bag-of-Tasks Scheduling Problem (DBoTSP) in heterogeneous multi-cloud environment. Bag-of-Tasks (BoT) are a well-known model that processes big-data applications supporting embarrassingly parallel jobs with independent tasks. This dataset considers the dynamic batch mode scheduling environment where tasks are first collected in a set (called BoT) that will be examined for scheduling at predefined times. The execution results of this dataset will be communicated to you as soon as our paper will be published. For further informations, please contact me at : [email protected]
