SUMMARY:P41 - Adaptive Execution Planning in Biomedical Workflow Managemen
 t Systems
DESCRIPTION:Poster\n\nP41 - Adaptive Execution Planning in Biomedical Work
 flow Management Systems\n\nJaros, Treeby, Jaros\n\nBiomedical simulations 
 require very powerful computers. Their execution is described by a workflo
 w consisting of a number of different cooperating tasks. The manual execut
 ion of individual tasks may be tedious for expert users, but prohibiting f
 or most inexperienced clinicians. k-Dispatch offers a ‘run and forge
 t’ approach where the users are completely screened out from th
 e complexity of HPC systems. k-Dispatch provides task scheduling, executio
 n, monitoring, and fault tolerance. Since the task execution configuration
  strongly affects the final tasks mapping on the computational resources, 
 the execution planning is of the highest priority. Unlike other tools, k-D
 ispatch considers a variable amount of computational resources per individ
 ual tasks. Since the scaling of the individual HPC codes is never perfect,
  k-Dispatch may find such a good mapping even an experienced user would mi
 ss. The proposed adaptive execution planning is based on collected perform
 ance data and the current cluster utilization monitoring.
