Hi all,
Is there any special things to do to scale up SpecFem Globe ? I used
the latest version (Git) with default setup (I changed nchunks to 6 and
pml to .false.). That worked fine. Then I used nex_xi=nex_eta=528 and
nproc_xi=n_proc_eta=22 compiled using intel on a cray system (hopper) at
NERSC and I am getting a "negative mass matrix term for the ocean". I
had similar problems with another earlier version I customized to
include the latest Berkeley 3D model (which we would be happy to share
once the model is published) it works fine using 300 total processors
but crashes at 2904. Did I miss something obvious here ?
Many thanks for helping,
Cheers,
Yder
