A delay-based dynamic scheduling algorithm for bag-of-task workflows with stochastic task execution times in clouds

Cai, Zhicheng; Li, Xiaoping; Ruiz García, Rubén; Li, Qianmu (Elsevier, 2017-06)

[EN] Bag-of-Tasks (BoT) workflows are widespread in many big data analysis fields. However, there are very few cloud resource provisioning and scheduling algorithms tailored for BoT workflows. Furthermore, existing algorithms ...
Price forecasting for spot instances in Cloud computing

Cai, Zhicheng; Li, Xiaoping; Ruiz García, Rubén; Li, Qianmu (Elsevier, 2018-02)

[EN] Big data applications usually need to rent a large number of virtual machines from Cloud computing providers. As a result of the policies employed by Cloud providers, the prices of spot virtual machine instances ...
Resource Provisioning for Task-Batch Based Workflows with Deadlines in Public Clouds

Cai, Zhicheng; Li, Xiaoping; Ruiz García, Rubén (Institute of Electrical and Electronics Engineers (IEEE), 2019-09)

[EN] To meet the dynamic workload requirements in widespread task-batch based workflow applications, it is important to design algorithms for DAG-based platforms (such as Dryad, Spark and Pegasus) to rent virtual machines ...
