Charm++ parallel programming system

["Casey W. Stark" <caseywstark AT gmail.com>]

Hi Akhil.

I'm still in the early stages of learning charm, but where should I look in the git repo to start contributing to the AMR work? I'm very much interested in the solvers and such.

Best,

Casey

Hi Casey,

We have an AMR implementation on Charm. Right now it is just restricted to Advection simulations but we are working on it to make it a generic framework. Right now I do not have performance numbers for AMR. However, ChaNGa group can share performance numbers for the N-body simulations.

Regards,
Akhil

I am interested in tinkering with the charm++ particles and AMR frameworks (or just charm) for cosmological simulations. I realize there is changa, and I'm sure I could leverage some of the N-body work, but I am interested in Eularian hydro. I don't know if enzo developers (http://code.google.com/p/enzo/) have contacted the list before, but I'm sure some of them are interested as well.

Is anyone familiar with the performance of the particles/AMR frameworks well above 1,000 cores? I'm sure this depends a lot on the implementation and details of the solver used, but I figured someone might have tried this before.
