IPAM WORKSHOP: BIG DATA MEETS COMPUTATION

This workshop, to be held at IPAM in early 2017, will examine the interface of high performance computing (HPC) and big data. In HPC, one of the key challenges toward exascale computing is to overcome the communication bottleneck. Data motion tends to clearly limit the overall performance and determine the (enormous) energy consumption of future supercomputers; some even say “flops are for free.” Therefore, it is crucial to develop novel ways of efficiently representing, reducing, reconstructing, and transferring huge amounts of data. At the same time, the analysis of large sets of (simulation) data requires sophisticated data analytics, which, in return, becomes more and more computationally intensive and thus contributes increasingly to HPC. Hence, computing technology and Big Data technology are intrinsically linked and further insights, methods, and algorithms have to be considered jointly within that context. The fusion of HPC and Big Data is a young field with an endless number of applications and huge potential. This workshop seeks to be a catalyst at this frontier and will bring together leading innovators and pioneers from applied mathematics, computer science, and various applications areas. n
