Running more than one application simultaneously on a node can be the solution for better resource utilization. However, this approach of co-scheduling can also be the way to go for gaining a degree of flexibility with respect to process management that can enable some kind of interactivity even in the domain of high-performance computing. This chapter gives an introduction into such co-scheduling policies for running multiple MPI sessions concurrently and interactively within a single user allocation. The chapter initially introduces a taxonomy for classifying the different characteristics of such a flexible process management, and discusses actual manifestations thereof during the course of the reading. In doing so, real world examples are motivated and presented by means of ParaStation MPI, a high-performance MPI library supplemented by a complete framework comprising a scalable and dynamic process manager. In particular, four scheduling policies, implemented in ParaStation MPI, are detailed and evaluated by applying a benchmarking tool that has especially been developed for measuring interactivity and dynamicity metrics of job schedulers and process managers for high-performance computing.<\/jats:p>","DOI":"10.3233\/978-1-61499-730-6-46","type":"book-chapter","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:30:51Z","timestamp":1739979051000},"source":"Crossref","is-referenced-by-count":0,"title":["Allocation-Internal Co-Scheduling"],"prefix":"10.3233","author":[{"family":"Clauss Carsten","sequence":"additional","affiliation":[]},{"family":"Moschny Thomas","sequence":"additional","affiliation":[]},{"family":"Eicker Norbert","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Advances in Parallel Computing","Co-Scheduling of HPC Applications"],"original-title":[],"deposited":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:31:14Z","timestamp":1739979074000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-729-0&spage=46&doi=10.3233\/978-1-61499-730-6-46"}},"subtitle":["Interaction and Orchestration of Multiple Concurrent MPI Sessions"],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-730-6-46","relation":{},"ISSN":["0927-5452"],"issn-type":[{"value":"0927-5452","type":"print"}],"subject":[],"published":{"date-parts":[[2017]]}}}
