In the past decade, developments of computational technology around density functional theory (DFT) calculations have considerably increased the system sizes which can be practically simulated. The advent of robust high performance computing algorithms which scale linearly with system size has unlocked numerous opportunities for researchers. This fact enables computational physicists and chemists...
Hybrid Density Functional Theory (DFT) has recently gained popularity as an accurate model of electronic interactions in chemistry and materials science applications. The most computationally expensive part of hybrid DFT simulations is the calculation of exchange integrals between pairs of electrons. We present strategies to achieve improved load balancing and scalability for the parallel computation...
With ever growing data traffic the traditional mobile network architecture is struggling to cope. Network densification using heterogeneous networks supported by Cloud-RAN is one of the core concepts in terms of physical resources. The system achieves increased capacity by reducing the number of devices (commonly refered to as user equipment - UE) connected to any individual cell. Cloud-RAN decouples...
