Evolution of linear perturbations in spherically symmetric dust spacetime

Aug 19, 2014

Sean Febuary completed his PhD in Applied Mathematics at the University of Cape Town. Brief description of his work: The growth of cosmic structure (e.g. galaxies, clusters thereof) is poorly understood in inhomogeneous cosmological models. Such models were originally proposed…

New worker nodes

Aug 7, 2014

hardware, hpc

We've installed four new 600 series worker nodes on hex. This increases the core count by 256, and we hope to add a few more to both the hex and hpc clusters shortly. If you notice anything odd please let…

Changes to HPC

May 22, 2014

hardware, hpc

Our older cluster, hpc.uct.ac.za is undergoing several changes. The 200 series will soon be decomissioned. The nodes are old, have insufficient core density and are inefficient power-wise compared to more modern servers. The space in the racks is required for…
