Summer School on Hardware-aware Scientific Computing

Date and Place

October 4-15, 2021

Interdisciplinary Center for Scientific Computing (IWR), Heidelberg University (UHD), Germany and Department of Computational and Data Sciences (CDS) at Indian Institute of Science Bangalore (IISc).

The school will be a hybrid event with live sessions at both places and streaming to offsite participants.

This summer school is part of our HASC grant in the Indo-german Partnership programme that we have together with the Department of Computational and Data Sciences (CDS) at Indian Institute of Science Bangalore (IISc).


Bring together Ph.D. candidates from Mathematics, Computer Science and Scientific Computing to study the interplay of efficient numerical algorithms with modern computer hardware.


First week October 4-8 is filled with lectures covering all aspects from hardware, programming models and algorithms to applications.

Second week October 11-15 features small projects lead by a pair of supervisors from India and Germany.


  • Aspects of modern processor architectures
  • Programming models and accelerator programming
  • Scalable methods for solving partial differential equations (PDEs)
  • Optimal control of PDEs
  • Large-scale Bayesian interference and data assimilation
  • Energy-aware numerical methods


  • Konduri Aditya (CDS, IISc)
  • Peter Bastian (IWR, UHD)
  • Praveen Chandrashekar (TIFR CAM)
  • Sashikumaar Ganesan (CDS, IISc)
  • Roland Herzog (IWR, UHD)
  • Vincent Heuveline (IWR, UHD)
  • Guido Kanschat (IWR, UHD)
  • Phani Motamarri (CDS, IISc)
  • Dirk Pleiter (KTH, Stockholm)
  • Robert Scheichl (IAM/IWR, UHD)
  • Deepak Subramani (CDS, IISc)
  • Jakob Zech (IWR, UHD)
