HPC series comparison
A comparison of the speed of the various cores in our clusters. Series100 (new): Intel Xeon Gold 6138, 2GHz Series600 (hex): AMD Opetron 6376, 2.3GHz Series400 (hal): Intel Xeon 5506, 2.1GHz SeriesGPU (new): Intel Xeon Gold …
New cluster nodes
It has been a long time in coming, several years in fact, but the first of our new worker nodes went live today on our POC cluster. There is still much to be done, Infiniband is not yet ready, the…
GPU cluster
The new GPU nodes have been installed into our POC cluster and are currently running jobs. We installed the servers into our SLURM cluster to allow us to develop hands on experience in provisioning SLURM partitions with GPU resources, something …
User based CIFS read\write mounts
First you need to ensure that setuid root is set on the CIFS mount executable: chmod u+s /sbin/mount.cifs In order for a user to mount a CIFS share it must be in the /etc/fstab file in the following format: //researchdata.uct.ac.za/<MYDISK>…
Acknowledgements, CPU hours and HPC shutdown
Achievements: Earlier this year we listed our 100th acknowledgement, 20 million computational hours and 2 million jobs processed since inception in 2009. If you have recently published work acknowledging usage of the HPC cluster please let us know. PBS script…
Changes to the UCT Hex HPC cluster
If you no longer require your HPC account please let us know. We will shortly begin disabling accounts of those researchers whose accounts have expired. Due to continued abuse of our cluster resources we are immediately reducing the maximum wall…
Singularity
We have installed Singularity onto Hex and Hal. Singularity is a containerization system that allows users and admins to create contained operating systems and environments. Don’t like SLES on HPC, then run Ubuntu. Don’t want our version of OpenMPI then…
Update feedback
The beegfs cluster was updated to 2015.03.r23. The fhgfs volume is back up and mounted on all nodes. During the Infiniband switch firmware upgrade an error was encountered. We have logged a support call with Mellanox regarding this. The switch …
Upcoming shutdown
BDC Shut down The Bremner data centre is being shut down completely on Sunday the 12th of February between 08:00 and 17:00. The HAL cluster will be off-line during this time. This will not affect jobs running on HEX. Head…
