UCT Computer Science are offering an honours course in Desktop High-Performance Computing: comparative parallel programming languages for multicore and accelerator architectures. This course is open to non-CS and non-UCT people and will run in Room 303 of the CS Building
…BackBlaze test
We've started to test the new BackBlaze disk unit. It's presenting an iSCSI mount but we don't have sufficient switch ports to wire up all our worker nodes. As a compromise we've made the iSCSI mount available to nodes 408…
Longest job to date
Today one of our users ran the longest job our cluster has hosted so far: 10,780km, submitted from the campus of the Australian National University. ;-)
Plans for 2012
Firstly a big thanks to all those who made use of our infrastructure last year, we accumulated over 114,000 CPU hours and increased our core count from 24 to 150. Our plans for 2012 is to grow this resource and
…New servers
Our VMware infrastructure is being upgraded so we got some hand-me-downs. 2 x BL460 servers with 8 cores and 32GB of RAM each. These have been added to the 400M series. This brings our HPC cluster up to just over…
Keeping up appearances
One of Scientific Linux's stronger points is its stability. It achieves this however by lagging considerably in its suite of default packages, even those provided by the EPEL repository. This is all well and good until some enthusiastic coven of…
New worker nodes
We've added two new nodes, 213 and 214, to the 200 series. Both nodes have 8GB of RAM. This brings our cluster up to 136 cores.…
RAM upgrade and more worker nodes
The RAM of worker node 209 has been upgraded from 4 to 8GB and the node moved back to the 200 series. We will be deploying a few more 200 series and at least 1 more 400M series worker nodes…
Gluster wobble
So we've been making use of GlusterFS for a while now and generally it's been great. Gluster allows us to present unused space on a number of networked servers (our HPC worker nodes) as a single disk pool and make…
