Un-drifted gparts error in L0300N2256 DMONLY
I've been running a 2256^3 dark matter only box on Irene. This has run for about 5 days now on 108 nodes with 2 MPI ranks per node and 24 threads per MPI rank. It reached z=0.7 but then crashed with many instances of the following error:
[0183] [09700.9] runner_doiact_grav.h:runner_dopair_grav_pp():722: Un-drifted gparts
I ran swift with
ccc_mprun ./swiftsim/examples/swift_mpi --restart --verbose=1 --self-gravity --cosmology --pin --threads=24 EAGLE-XL_L0300N2256.yml
and the configure line was
./configure CC=icc CFLAGS=-qopt-zmm-usage=high --enable-ipo --with-hdf5 \
