A general idea of the kind of applications that run on Roadrunner can be seen in the SC'08 Initial report. The application described there is a neutron-transport model. The kind of the communication pattern seen in this application is described as a wavefront. For the Roadrunner it was ported from

Note that as for nuke explosions i have no idea how those look like - maybe someone more knowledgeable wants to comment on that. As a total layman there i would suspect that it's important where the protons/neutrons/whatever-tons/supertiny-tons are located. I'd be modelling that naively usin

In this case we were discussing roadrunner and the CELL processors used there exclusively for nuke explosions. That's a very specific user case. Now all that code as i understand it that ran there was classified codes - so i suppose possible reports will be kept secret as well. Yet it would b

Concur! Porting code to BGL was more or less trivial. "porting" to CUDA means basically re-imagining how to parallelize your code. On Thu, Apr 4, 2013 at 8:22 AM, Prentice Bisbal wrote: > On 04/03/2013 11:42 AM, Geoffrey Jacobs wrote: > > On 04/03/2013 08:27 AM, Bret Stouder wrote: > >> Prent
