Dear Einstein Toolkit Team,
I hope this email finds you well. I am writing to inquire about a specific
parameter used in the simulation command for binary black hole (BBH) mergers in
the Einstein Toolkit's Gallery.
Recently, I have been experimenting with running BBH simulations using the
following command:
simfactory/bin/sim create-submit GW150914_28 --define N 28 --parfile
par/GW150914/GW150914.rpar --procs 128 --walltime 24:00:00
In this command, I have noticed the use of the parameter "N" with a value of
28. However, when I changed the value of "N" to 20, I observed a significant
reduction in the total runtime of the simulation, despite the fact that the
merger time of the binary black holes increased from around 900M to 1000M.
Could you please provide some clarification on the purpose of the "N" parameter
in this simulation context? Additionally, could you explain why changing the
value of "N" affects the runtime of the simulation and the merger time of the
black holes?
I would greatly appreciate any insights or explanations you could provide on
this matter. Thank you very much for your time and assistance.
Sincerely, Xinyue Bian(an undergraduate who has a bit interest in NR)
