SUMMARY:k-Dispatch: A Workflow Management System for the Automated Executi
 on of Biomedical Ultrasound Simulations on Remote Computing Resources
DESCRIPTION:Paper\n\nk-Dispatch: A Workflow Management System for the Auto
 mated Execution of Biomedical Ultrasound Simulations on Remote Computing R
 esources\n\nJaros, Treeby, Georgiou, Jaros\n\nTherapeutic ultrasound is in
 creasingly being used for applications in oncology, drug delivery, and neu
 rostimulation. In order to adapt the treatment procedures to patient needs
 , complex physical models have to be evaluated prior to the treatment. The
 se models, however, require intensive computations that can only be satisf
 ied by cloud and HPC facilities. Unfortunately, employing these facilities
  and executing the required computations is not straightforward even for e
 xperienced developers. <br /> k-Dispatch is a novel workflow management sy
 stem aimed at modelling biomedical ultrasound procedures using the open-so
 urce k-Wave acoustic toolbox. It allows ultrasound procedures to be upload
 ed with a single click and provides a notification when the result is read
 y for download. Inside k-Dispatch, there is a complex workflow management 
 system which decodes the workflow graph, optimizes the workflow execution 
 parameters, submits jobs to remote computing facilities, monitors their pr
 ogress, and logs the consumed core hours. In this paper, the architecture 
 and deployment of k-Dispatch are discussed, including the approach used fo
 r workflow optimization. A key innovation is the use of previous performan
 ce data to automatically select the utilised hardware and execution parame
 ters. A review of related work is also given, including workflow managemen
 t systems, batch schedulers, and cluster simulators.\n\nDomain: Emerging A
