45 minutes is a long time for a computer: 2,700 long seconds. For a supercomputer like ARCHER that's a lot of time to spend getting ready to do work, but this is the problem faced by the firedrake team who we work with as part of the Marine Technology project.

Last Thursday (25th April) saw the prizegiving for the University Sustainability Awards. We've been involved with the awards for a few years now and have seen them change and adapt as we have. Last year EPCC won a Silver and this year we have achieved the top award, Gold.
