Add seminar to my diary


The CMB provides us a unique view of the very early Universe and hence profound insights into both cosmology and fundamental physics at the highest energies. However the CMB signal is extraordinarily faint, requiring us to gather extremely large data sets. The data sets also contain complex correlations that preclude divide-and-conquer analyses and necessitate the use of the largest available supercomputers. In this talk I will discuss the past, present and future of CMB data analysis algorithms and their massively parallel implementations under the evolving drivers of CMB science goals and HPC system architectures.
