--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------
SOLUTION:
The output directory specified as OutputDir outputs in the parameter file doesn’t exist. Create it first, then run gadget.

SOLUTION:
Did you really give gadget a parameter file, or did you maybe by mistake give it the IC file as cmdline arg?

I've found something odd!
The mass content accounts only for Omega=2.7597e+08,
but you specified Omega=0.276 in the parameterfile.
SOLUTION:
Something went wrong with the units. Make sure you specified the units in the gadget file correctly. MUSIC uses the following default values:
UnitLength_in_cm 3.08568025e24 ; 1.0 Mpc
UnitMass_in_g 1.989e43 ; 1.0e10 solar masses

SOLUTION:
Make sure all the softening parameters (Softening*) in your parameter file are non-zero. They are needed to compute the timestep.
No domain decomposition that stays within memory bounds is possible.¶
Gadget2 exits after message:
No domain decomposition that stays within memory bounds is possible.
SOLUTION:
Increase *AllocFactor in your params file. (Or apparently run on more processors)
