Pegasus has been used to run workflows with up to 1 million tasks that process tens of terabytes of data at a time. Pegasus WMS bridges the scientific domain and the execution environment by automatically mapping high-level workflow descriptions onto distributed resources. It automatically locates the necessary input data and computational resources required by a workflow, and plans out all of the required data transfer and job submission operations required to execute the workflow. Pegasus enables scientists to construct workflows in abstract terms without worrying about the details of the underlying execution environment or the particulars of the low-level specifications required by the middleware (Condor, Globus, Amazon EC2, etc.). In the process, Pegasus can plan and optimize the workflow to enable efficient, high-performance execution of large workflows on complex, distributed infrastructures. Pegasus has a number of features that contribute to its usability and effectiveness: - Portability / Reuse – User-created workflows can easily be run in different environments without alteration. Pegasus currently runs workflows on top of Condor pools, Grid infrastructures such as Open Science Grid and XSEDE, Amazon EC2, ","default_branch":null,"files":null,"tree":[],"storefront":"/r/pegasus-isi","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/pegasus-isi/pegasus/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
