The HPC team have been making use of “module” for a while now. A few of our users are aware of its availability but it hasn’t really been disclosed as a “production” ready setup. Well, it is now. Scientific packages …
FhGFS Metadata server migration
FhGFS is a awesome distributed parallel filesystem. Its simple and so powerful with a RDMA backend that knocks the performance socks off other distributed filesystems, IMHO. Today however I needed to migrate the metadata server from one host ( a…

The eResearch Africa 2014 conference starts this weekend, you can keep up to date on the conference activities here.…
Hard-Soft limits
We have raised the hard-soft limits of the hex cluster to 4864. The implication is that users normally have access to 48 cores, however when the cluster is not heavily loaded this limit will be automatically raised to 64. The…

A reminder to our users that currently the maximum core limit is 32 soft / 48 hard. This means that at times when the cluster is not very busy users will be able to submit jobs that consume 48 cores…
Arecibo data
ICTS HPC is currently processing data captured at Arecibo Observatory:
We'll blog more on this project later in September. In the interim we've added two new nodes to series600A. These nodes will be dedicated to the Arecibo Queue until…

Jonathan Bergh conducted the following benchmarks against our facilities. Tests were run on the HEX 64core AMD 6376 machine to test the
scaling of a standardised CFD problem over an increasing no. of cores.
The test mesh was a turbomachinery…
Evolution of linear perturbations in spherically symmetric dust spacetime
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
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…
