Okay I guess I can disable CH4:UCX win allocate.

MPICH has a device configure option. That's where you set it. OFI is the default. Somebody had to be setting UCX explicitly.

You should change it to OFI until someone figures out where the RMA UCX bug is.

Nemesis isn't maintained anymore. I don't think that's a good idea. Debian needs to just not support releases of MPI libraries that don't work. RMA worked in MPICH in the...

I cannot reproduce on my machine (AArch64, Ubuntu 20.04, GCC 9.4). I do not have a true Debian system to test. ``` jhammond@orin:/samsung/NWChem/github/src$ /samsung/MPICH/ucx-install/bin/mpichversion MPICH Version: 4.1a1 MPICH Release date:...

@drew-parsons see https://github.com/pmodels/armci-mpi/pull/40. can you try that branch with `ARMCI_DISABLE_SHM_ACC=1`? Also, if you set `ARMCI_VERBOSE=2`, it will print out the full MPI library version, which should be useful for debugging.

But it seems that it does not fix the problem, unfortunately. Do I read that correctly? `ARMCI_USE_ALLOC_SHM=0` might be the next level up, which may turn off shared memory inside...

I will test UCX versions next.

Weird. This worked in the past but it isn’t tested regularly. If you have time to test old releases, it would help to know when it was broken. Normally the...

I don’t think DUCC and hyperpolarizability should be used together. In any case, that CCSD works doesn’t mean CCSDT is fixed.
