…Maths jobs submitted to HPC cluster
Our first user has started submitting jobs to the cluster. The software
being used is auto07p for continuation and bifurcation problems in
ordinary differential equations. Auto07 can be compiled with OMP to
make it multi-cpu aware. Currently each job makes…
Parallel code, benefits and pit-falls
Most high end platforms for high performance computing are equipped with multi-core CPUs. In order to fully utilize the CPUs multiple jobs must be run on each platform or the code must be changed to utilize multiple CPUs. There are…
Installed and tested a proof of concept cluster
Installed Oracle Virtual box on a laptop and created 3 Scientific Linux
virtual machines. Installed Torque PBS with one head node and 2 worker
nodes. Installed worker node software on head node to test pbs_mom,
worked fine. Replaced the default…
New worker node
Added srvslngrd011.uct.ac.za to the cluster. This is the old CE which has now been virtualized. It's a HP BL460 HP blade
with 8 cpus and 16GB of RAM. This brings our current cluster up to 24
cpus, available to both…
First science jobs running on UCT cluster
This weekend, Ake Fagereng from the UCT Geology department became
the first UCT researcher to use the UCT High Performance Cluster in
ICTS's data centre. The HPC allowed him to run several jobs at
once; with each job taking between…
