Hi,
I am lost. We are building a new Cray (HPE) system. Software wise, it
looks like a Cray (PrgEnv-accc, cray-mpich is preferred).
However it is made of those new AMD chips (128 cores on a node in co-located
pairs of 64 with a shared memory access penalty between pairs). There is no
GNI. OpenFabrics is the default and UDP can be sort of made to work. I think
I need something in between:

./build charm++ mpi-linux-x86_64 mpicxx --with-production

and

./build charm++ mpi-linux-x86_64 craycc --with-production

I've tried a lot of other crazy stuff (like pretending it is an XC40,
renaming compiler env vars, etc.), but no luck yet. I keep thinking I can
pull pieces out of one file to fill in another, but I have not hit the magic
combination. Any help appreciated. Thanks.
Ray
