TAT/Slab error running BBHLowRes

I see the following error when running '/repos/einsteinexamples/par/arXiv-1111.3344/bbh/BBHLowRes.par':

WARNING level 0 from host mars process 0 while executing schedule bin BoundaryConditions, routine RotatingSymmetry180::Rot180_ApplyBC in thorn RotatingSymmetry180, file /home/mikael/Astronomy/GeneralRelativity/ET/Cactus/configs/sim/build/RotatingSymmetry180/rotatingsymmetry180.c:447: -> TAT/Slab can only be used if there is a single local component per MPI process

What to do? Something in the .par file that can be adjusted?

    Many thanks for swift reply!

    The binary was built with the following command:

    ./simfactory/bin/sim build --mdbkey make 'make -j6' --thornlist=manifest/einsteintoolkit.th

    since I have 8 cores and thought should compile with less than max.

    Should I rebuild with 'make -j2' above?

    Thanks, Mikael

    It does not matter how you built the executable. But when you run it, you need to use at least 2 MPI processes.

    Thanks, I'm new to this so I didn't realize I should run the executable using exe/sim/mpirun. It's running now and there are indeed two processes running. It will take a while ...

    Thx, Mikael
