Charm++ parallel programming system

[Ralf Gunter Correa Carvalho <correac2 AT illinois.edu>]

Hi Vinícius,

As far as I know, the main release of charm does not support adding new hosts during runtime. However, there is ongoing work that allows a modified scheduler to dynamically shrink or expand the number of running nodes, though my understanding of it is that it would still mostly work from a given nodelist group (just possibly using fewer or more of those nodes.) Here's a set of slides describing that feature:

If you could into a little bit of detail about what exactly you want to do (e.g. your cluster setup), we may be able to help you out.

Hi forum members,

CHARM ++ can add nodes at runtime at a scalable way (elastic)?
From what I researched, CHARM++ can run on N nodes previously defined by the command:

./charrun pN + ./Program

Where pN + respects the "charelist"
It is possible to add nodes in "charelist" at runtime?

Thanks,
Vinícius M.
