Hi All,

I have a question about isomalloc. Don't I need this to be able to run a job on more than one node? What does the MPI_THREAD_SINGLE mean? Could this be the problem with slowness on multi-node run? Below is a cope of my output header:

Charm++> Running on MPI version: 2.0 multi-thread support: MPI_THREAD_SINGLE (max supported: MPI_THREAD_SINGLE)
[0] isomalloc.c> Disabling isomalloc because mmap() does not work
Charm++> Running on 2 unique compute nodes (32-way SMP).
Charm++> cpu topology info is gathered in 0.016 seconds.
