Charm++ parallel programming system

["Kale, Laxmikant V" <kale AT illinois.edu>]

Pritish, I think they are interested in the cource code, rather than the executable. I assume it is easy to find (but the instructions about the right repositories, and branch might be confusing in that respect. I assume the BH code is invariant, but just that it needs the new MeshStreamer library, which requires a particular branch of charm++..  right?

Yes, there is such a piece of code, called CharmBH. Please follow these steps to get an executable:

1. Obtain a copy of Charm++

2. build the 'MeshStreamer' library in Charm++: go to the tmp/libs/ck-libs/MeshStreamer directory and do a 'make'

3. Run the attached script to get an executable of barnes. The only argument to the script should be the path to your Charm++ installation. The script will clone the relevant repositories and switch to the correct branch before starting the compilation.

./install.sh <path to charm++ installation> 

Please let me know if you run into errors.

Hello,

We are looking for a lightweight code that does the N-Body calculations. ChaNGa is there but it is a very heavy code. Is there something available, like leanMD, for N-body calculations?

Thanks,

Shad
