SUMMARY:Managing Workflow Malleability in Urgent Computing for Earthquake 
 Alerts
DESCRIPTION:Jorge Ejarque, Marisol Monterrubio-Velasco, and Cedric Bhihe (
 Barcelona Supercomputing Center (BSC)); Marta Pienkowska (ETH Zürich); and
  Josep de la Puente and Rosa M. Badia (Barcelona Supercomputing Center (BS
 C))\n\nWhen large earthquakes happen, first responders need fast and accur
 ate information regarding their impact. UCIS4EQ is an urgent computing pla
 tform that estimates ground shaking based on high-performance parallel 3D 
 simulations. In this work, we present the PyCOMPSs implementation of UCIS4
 EQ towards urgent high-performance computing with a particular focus on pr
 oviding a malleability mechanism. This allows UCIS4EQ to scan for data upd
 ates during runtime and dynamically incorporate said data into its executi
 on. This involves, in particular, leveraging several HPC jobs. The impleme
 ntation has been validated with data from the Samos Izmir earthquake. The 
 malleable version of the workflow can reduce the use of computational reso
 urces by 40\% while reducing the variability of the results and keeping th
 e same time-to-solution as a non-malleable run.\n\nTag: Applications and A
