Hi Enzo,
As the website warns: "Note that the simulation requires about 82 GB of RAM, *so most likely you will need to use a cluster.*" As for the error, MPI is probably seeing only one node (your laptop) so requesting 16 is throwing an error.

Greetings to all.
I've been having some problems running the GW150914 simulation. When following the tutorial on " https://einsteintoolkit.org/gallery/bbh/cr.html " , I run into problems when running the parfile, specifically when running
simfactory/bin/sim create-submit GW150914_28 --define N 28 --parfile par/GW150914/GW150914.rpar --procs 128 --walltime 24:00:00
This leads to the error
Parameter file: /home/enzo/Cactus/par/GW150914/GW150914.rpar Skeleton Created Job directory: "/home/enzo/simulations/GW150914_28" Executable: "/home/enzo/Cactus/exe/cactus_sim" Option list: "/home/enzo/simulations/GW150914_28/SIMFACTORY/cfg/OptionList" Submit script: "/home/enzo/simulations/GW150914_28/SIMFACTORY/run/SubmitScript" Run script: "/home/enzo/simulations/GW150914_28/SIMFACTORY/run/RunScript" Parameter file: "/home/enzo/simulations/GW150914_28/SIMFACTORY/par/GW150914.rpar" Assigned restart id: 0
Error: Too many nodes specified: nodes=16 (maxnodes is 1) Aborting Simfactory.
I am inclined to believe this is because I am running it on my own laptop, but I would nonetheless like to know exactly what does that error mean and if I can fix it somehow.
I would really appreciate your help, thank you :)
