Hello,

Which version of Charm++ are you using?

We recently fixed some issues to achieve better scalability of our ibverbs implementation.You should be able to launch more than 2k if you use the parameters below (for larger scale runs) with charmrun:

++verbose ++scalable-start ++batch 128

Thanks,

Abhishek

Now, I am facing another problem that ibverb doesn't support more than a couple thousand processors.

Adding ++scalable-start and ++batch extremely slows things down.
