Hello,

Could you provide some of the critical output from the unsuccessful compilation attempts?

We're currently working on getting access to that architecture so we can provide more useful assistance.

Hello again,
  Just a follow up of things I omitted that may be helpful.  The system is running SLES-15 and my module list looks like this:

rsheppar@login1:/N/soft/sles15/namd/build/namd_july_2021./charm-6.10.2/src/arch> module list

Currently Loaded Modules:
  1) aocc/2.2.0.1   3) craype-x86-rome/1.0.0   5) craype-network-ofi   7) perftools-base/21.05.0   9) cray-libsci/21.05.1.1
  2) craype/2.7.7   4) libfabric/1.11.0.3.71   6) cray-dsmml/0.1.5     8) cray-mpich/8.1.5        10) PrgEnv-aocc/8.0.0


Thanks in advance for any help building here.
        Ray

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
