how to use multirun in v2.6.5

Asked by Jack

Hi,

I'm trying to generate more than 100k events so require to use multi_run as suggested in the README, however the suggestions in the README seem to mention something that doesn't exist.

"This command can be launched via the madevent user interface
./bin/madevent using the following command:
multi_run NBRUN [RUN_NAME] [options]
For more information about this command (valid options), you can type
`help multi_run` inside the interface."

in the bin directory all that is there is
compile.py
mg5
mg5_aMC.

There is no ./bin/madevent

doing ./mg5_aMC and help multi_run also does not return anything.

Has ./bin/madevent been removed in v2.6.5? And if so how do I do multi_run?

I tried to follow the help in https://answers.launchpad.net/mg5amcnlo/+question/283732

However when I make control.txt:

import model heft
generate p p > h > a a
display diagrams
output mytestdir
launch
multi_run 2

and run this with ./../../MG5_aMC_v2_6_5/bin/mg5_aMC control.txt

I just get the error "Command "multi_run" not recognized, please try again"

Thanks for any help

Hi,

The madevent executable is in the bin directory of the directory created.
so in your case in mytestdir/bin
It's still exists in 2.6.5

You can also use the following script:

> import model heft
> generate p p > h > a a
> display diagrams
> output mytestdir
> launch -i
> multi_run 2

The "-i" option of the lauch is the equivalent option of the ./bin/madevent
which put you in a new environment where you have all the function available to control
event generation/plot/...

Cheers,

Olivier
