Hi,

I was wondering if charm++ can support following scenario:

The required input data has already been distributed in memory across PEs, and for charm++ application, each PE only handles the input data in the local memory at the very beginning. It seems that I manually map chares to PEs.

Is there any issue for charm++ to support it? I guess the charm++ runtime should know the mapping between PEs and chares. So I should let charm++ know where the data is located? Is there any similar example I can refer to to implement such routine?

Any comments or suggestions are really appreciated! Thank you!

Regards,

Qian
