Hello-
I am trying to resolve a hang I'm seeing on the Cray XC with the
gni-crayxc build. I'm building with the gcc compiler, and my build
command is:
./build charm++ gni-crayxc persistent smp --with-production

Running megatest with +ppn2 or higher results in an intermittent
megatest hang. The higher the ppn value, the more likely the hang.
Most of the hangs occur here:
test 43: initiated [multi migration (jackie)]

Could someone from Charm get back to me?
Thanks much
Ted Packwood
