The conversations rarely go well, and in many companies, the inability to get finance on board becomes a major roadblock to securing top-level buy-in. I lead something of … Read more
Introduction Last year, I was faced with a user issue that initially confused me. A user running open-source CFD software told me they had installed the same software on their laptop, and it was running much faster on their 8-core workstation compared to a 120-core HPC-optimised machine on a cloud HPC cluster.

Introduction It’s mid-2013 and I have just graduated with a physics degree. I really enjoyed the theoretical component, but the computational and experimental labs were rather uninspiring. I still wanted to do something more practical, with foreseeable benefits, but I was also afraid of specialising myself into oblivion. A few months of speculative emails and … Read more
