SUMMARY:WONDERS: Integrating WOW, PONDER, and SCALE for Enhanced Schedulin
 g Performance
DESCRIPTION:Fabian Lehmann (Humboldt-Universität zu Berlin); Jonathan Rau,
  Jonathan Bader, and Odej Kao (Technical University of Berlin); and Ulf Le
 ser (Humboldt-Universität zu Berlin)\n\nRecent scientific workflow managem
 ent systems, such as Nextflow, put a huge focus on portability of workflow
 s. Portability encompasses replacing both the target infrastructure and th
 e input dataset. The more portable systems become, the more the importance
  of automatic adaptation and optimization increases. Strategies to optimiz
 e the execution of scientific workflows are often evaluated in simulation,
  and only for the individual strategy. Accordingly, it is unclear how diff
 erent strategies affect each other.\n\nIn this work, we fuse three strateg
 ies to optimize workflow execution. First, WOW: an approach that focuses o
 n location-aware scheduling. Second, PONDER: an approach that predicts tas
 k memory consumption and sizes the tasks accordingly. And third, SCALE: an
  approach to predict task CPU and size it accordingly. \n\nWe test all thr
 ee approaches together and investigate their synergies. Our results show t
 hat the whole is greater than the sum of its parts. We achieve makespan re
 ductions of up to 67.4%.\n\nTag: Research & ACM SRC Posters\n\nRegistratio
