Why do we need HPC? • Larger FE Models • Assemblies instead of single parts and defeaturing Lots of computations!!

• Mesh fidelity continues to increase • More equations to solve More computations!!

• More complex physics being analyzed • Nonlinear, Dynamics, Multiphysics More computations!!

• Parametric studies, Optimization More computations!!

OK, we need more computations so we just buy faster processors, right?

Wrong ! Main problem is you make processors faster by making transistors on a chip perform more operations per unit time. This uses more power and generates lots of heat. That’s why you won’t find many processors faster than about 3.6 GHz for several years now. Also why there are so many datacentres in Ireland – cooling much cheaper here !

How do we improve performance? We can sit around and wait for quantum computing (or some other magic bullet) to become mainstream OR …. • Multiple cores on a single chip • Parallel computing • Use GPUs • More and faster RAM • Faster storage (SSD) • Faster interconnections between cores • Faster interconnection between devices

I’ve got my superfast cloud access, but I have a few problems ! The 3D rendering of my models are jerky and frustrating to work with on the cloud • Nice DCV My simulations run blisteringly fast but it takes me forever to upload and download results – some time saving this is ! • CADFEM C.A.V.E. • Post process on the cloud and save to Amazon EC2 I can’t access licences from our office licence server on the cloud? • Open VPN / Corporate VPN • Consider putting the licence server in the cloud too I want to run a big job on the cloud but don’t have enough HPC packs and/or need extra licences temporarily? • eCADFEM © CADFEM 2015

Cloud Computing Options • CADFEM Cloud • • • •

Optimised for ANSYS Specialised viewer software for remote 3D rendering (Nice DCV) CADFEM CAVE to shrink results for local viewing High end solution

• ICHEC • Massively powerful • Suitable for batch jobs only • Still necessary to upload and download data

•Amazon Cloud • Very flexible – pay for what you use, scale machines as needed on the fly • Previously graphics could be a bit slow for 3D rendering, now addressed with GPU instances. • All pre- and post- processing done on the cloud • Can also use Nice DCV

The Future

Where we are now • Three separate cloud solutions • Pick the one you want to use • No interaction between them

Where we would like to go • Single port of call • Select the right tool for the job • Combine different clouds together • Share results across different cloud types
