Hi Rod, That might be tricky. I had anticipated standing at a whiteboard and winging it, and I am not aware of us having a room with the right gear to webcast that, although if someone wants to prove me wrong I'm all ears.

Informal finite element course.
by David Ham 11 Nov '13

11 Nov '13

Hi All, Having been extensively lobbied over many months, and also being aware that I am explaining basic finite element repeatedly to different people, I have decided to cave in to the pressure and actually do something a bit more organised. Following very loosely the model of Colin's FEEC course, I think the plan would be to do a session of 90 minutes or so perhaps once a week for a few weeks until we have got far enough. The target market is anyone who doesn't yet know how to derive the finite element method for systems like Poisson, the wave equation, advection diffusion etc. We would cover the basic theory of finite element, and matters such as quadrature, boundary conditions, Galerkin orthogonality and so on. At this stage I am just gauging interest, so please reply (to list) indicating if you would be interested. This will enable me to work out whether its worth doing and where I should do it. Regards, David -- Dr David Ham Departments of Mathematics and Computing Imperial College London http://www.imperial.ac.uk/people/david.ham

DOLFIN: Expressive and scalable finite element simulation beyond 1000 cores
by Florian Rathgeber 23 Oct '13

23 Oct '13

Some of you will have seen this, if you haven't it's well worth a read to see what's cooking in DOLFIN with regards to parallel scaling: http://www.hector.ac.uk/cse/distributedcse/reports/UniDOLFIN/UniDOLFIN.pdf It addresses the lack of (i) scalable parallel I/O, (ii) parallel mesh refinement and (iii) hybrid MPI + OpenMP in DOLFIN.

Fwd: LMS Computer Science Day - on Mathematics Research Beyond the Blackboard. 29 Oct. All welcome!

This looks like quite an exciting day. Paul Begin forwarded message: From: Tom Melham <Tom.Melham(a)CS.OX.AC.UK<mailto:Tom.Melham@CS.OX.AC.UK>> Date: 21 October 2013 22:11:11 GMT+01:00 To: <cphc-members(a)JISCMAIL.AC.UK<mailto:cphc-members@JISCMAIL.AC.UK>> Subject: LMS Computer Science Day - on Mathematics Research Beyond the Blackboard. 29 Oct. All welcome! Reply-To: Tom Melham <Tom.Melham(a)CS.OX.AC.UK<mailto:Tom.Melham@CS.OX.AC.UK>> Dear Colleagues, Please allow me to remind you of the "Computer Science Day" run by the London Mathematical Society, which this year is co-organised by Professor Ursula Martin and is on the topic of Mathematics Research Beyond the Blackboard. We still have a few places left, and warmly welcome your participation. We have a fantastic line-up of speakers: John Harrison (Intel), Nick Trefethen (Oxford), Ursula Martin (QM), and Steve Linton (St Andrews). The theme of the colloquium is the way in which computer science has made a variety of contributions to how contemporary mathematics research is done. This forward-looking colloquium will take place at the London Mathematical Society on Tuesday 29 October, and all interested mathematicians and computer scientists are welcome to come. Some funds are available to help with travel costs of PhD students. I attach a poster about the colloquium, and I would be very grateful if you would circulate this to colleagues in Computer Science and Mathematics. Please see the poster for how to register. All best regards, Tom Melham Chair, Computer Science Committee, LMS

AFAIK we haven't yet done this. It's a bit off the short term critical path which probably explains why nobody has looked at it, although we really should since we want to claim performance portability in upcoming publications, and this is a potential bottleneck.
