How to run the experiment¶
Launch Autosubmit with the command:
autosubmit run EXPID
EXPID is the experiment identifier.
Options:
usage: autosubmit run [-h] expid
expid experiment identifier
-nt --notransitive
prevents doing the transitive reduction when plotting the workflow
-v --update_version
update the experiment version to match the actual autosubmit version
-st --start_time
Sets the starting time for the experiment. Accepted format: 'yyyy-mm-dd HH:MM:SS' or 'HH:MM:SS' (defaults to current day).
-sa --start_after
Sets a experiment expid that will be tracked for completion. When this experiment is completed, the current instance of Autosubmit run will start.
-rm --run_members
Sets a list of members allowed to run. The list must have the format '### ###' where '###' represents the name of the member as set in the conf files.
-h, --help show this help message and exit
Example:
autosubmit run cxxx
Important
If the autosubmit version is set on autosubmit.conf it must match the actual autosubmit version
Hint
It is recommended to launch it in background and with nohup
(continue running although the user who launched the process logs out).
Example:
nohup autosubmit run cxxx &
Important
Before launching Autosubmit check password-less ssh is feasible (HPCName is the hostname):
Important
The host machine has to be able to access HPC’s/Clusters via password-less ssh. Make sure that the ssh key is in PEM format ssh-keygen -t rsa -b 4096 -C “email@email.com” -m PEM.
ssh HPCName
More info on password-less ssh can be found at: http://www.linuxproblem.org/art_9.html
Caution
After launching Autosubmit, one must be aware of login expiry limit and policy (if applicable for any HPC) and renew the login access accordingly (by using token/key etc) before expiry.
How to run an experiment that was created with another version¶
Important
First of all you have to stop your Autosubmit instance related with the experiment
Once you’ve already loaded / installed the Autosubmit version do you want:
autosubmit create EXPID
autosubmit recovery EXPID -s -all
autosubmit run EXPID -v
or
autosubmit updateversion EXPID
autosubmit run EXPID -v
EXPID is the experiment identifier. The most common problem when you change your Autosubmit version is the apparition of several Python errors. This is due to how Autosubmit saves internally the data, which can be incompatible between versions. The steps above represent the process to re-create (1) these internal data structures and to recover (2) the previous status of your experiment.
