The use of multi-processing is now becoming the “norm” with multiple cores now available in many consumer PCs and laptops. It is now much easier to start experimenting with speeding up your code at your desk and then transition to a larger resource such as Cardiff University’s supercomputer Raven. However, as expected, some jobs the Read more

All are welcome to attend, even if you are not planning to use the technologies its is great to see the cutting-edge research Cardiff Read more
We recently installed new nodes into our supercomputer. As part of the process we have to run tests to assess the new nodes. Since this was an extension to the existing infrastructure there were limits on how many high-speed links (or Infiniband (IB) connections) could be wired in, and the use for the nodes would Read more

Thankfully the weather has been fairly good to work outside and the main event being the new chillers were delivered over the weekend of the 6th/7th. All talks of “weather bombs” or more technically Read more
For users of ARCCA services, December is an important month due to our datacentre having been mostly shutdown whilst work is performed on the cooling infrastructure and other internal changes. This has required a disruption in our services but in the long-term provide a more resilient cooling infrastructure and space to house more hardware. Reasons Read more
