I am using Gadget4 to run the test case. The config files and parameter files are simply that were used for Gadget3, but have been modified to be consistent with Gadget4.

Hi,
Then it is ok. I got confused because you named the IC file as the snapshot. I believe Gadget will just ignore this if you pass Flag 2. But, again, I am confused, are you using Gadget-3 or 4 to restart the simulation?
Cheers,

Tiago,
Thank you so much for your response. I believe I'm using restart option "2" to run. This is how I run the case:
srun -N $SLURM_NNODES -n $SLURM_NPROCS ./Gadget4 box3_hr.par 2 44
Does that look OK?
Best,
Asitav

Hi Asitav,
I notice that the TimeBegin is still set to the original simulation IC (z=60.0). I am guessing here and hope someone with more experience can help you further. But it seems you are restarting a run from the snapshot that is not at z=60, is it right? If you want to restart from this snapshot, you should fix it to the redshift of the snapshot. In any case, I would recommend you use the Gadget flag to restart from the snapshot file instead of using it as the ICs. I believe the flag is "2", but you can check it by just running Gadget without a parameter file.
Cheers,

Hello all,
Sorry for spamming the mail-list with my earlier email. This e-mail corrects the subject line.
I am running a Gadget3 format snap file (Box/3hr) and I get byte mismatch on target vs src byte sizes. A similar post on the mail archive didn't help much since I don't have the same parameters set. I may be missing some configuration input parameters (see attached the Config.sh and parameter file). I am using files that are modified from existing Gadget3 Config and parameter files. The relevant error I get are:
READIC: filenr=0, './/snapdir_044/snap_044.0' contains:
180 READIC: Type 0 (gas): 0 (tot= 0) masstab= 0

Any inputs or suggestions would be great.
Thanks,
Asitav
