Autosubmit: a versatile tool to manage Weather and Climate Experiments in diverse Supercomputing Environments

Project description


Autosubmit is a tool to create, manage and monitor experiments using
Computing Clusters, HPC's and Supercomputers remotely via ssh.


HOW TO DEPLOY/SETUP AUTOSUBMIT FRAMEWORK
========================================

- Autosubmit has been tested:

with the following Operating Systems:
* Linux Debian

on the following HPC's/Clusters:
* Ithaca (IC3 machine)
* Stargate (IC3 machine)
* MareNostrum (BSC machine)
* MareNostrum3 (BSC machine)
* HECToR (EPCC machine)
* Lindgren (PDC machine)
* C2A (ECMWF machine)
* CCA (ECMWF machine)
* ARCHER (EPCC machine)

- Pre-requisties: These packages (bash, python2, sqlite3, git-scm > 1.8.2, subversion) must be available at local
machine. These packages (argparse, dateutil, pyparsing, numpy, pydotplus, matplotlib, paramiko) must be available for
python runtime. And the machine is also able to access HPC's/Clusters via password-less ssh.

- Install Autosubmit
> pip install autosubmit
or download, unpack and "python setup.py install"

- Create a repository for experiments: Say for example "/cfu/autosubmit" then "autosubmit configure" and follow
instructions

- Create a blank database: "autosubmit install"

HOW TO USE AUTOSUBMIT
=====================
> autosubmit -h

> autosubmit expid --HPC ithaca --description "experiment is about..."

Say for example, "cxxx" is 4 character based expid generated by system automatically.
First character is a letter, the other three alfa-numeric characters allow to identify uniquely the experiment.

> vi /cfu/autosubmit/cxxx/conf/expdef_cxxx.conf

> vi /cfu/autosubmit/cxxx/conf/autosubmit_cxxx.conf

> vi /cfu/autosubmit/cxxx/conf/platforms_cxxx.conf

> vi /cfu/autosubmit/cxxx/conf/jobs_cxxx.conf

> autosubmit create cxxx

> nohup autosubmit run cxxx

Cautions:
- Before launching autosubmit check the following stuff:
> ssh ithaca # (for example) check other HPC's where password-less ssh is feasible.
- 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 MONITOR EXPERIMENT
=========================

> autosubmit monitor -h

> autosubmit monitor cxxx
or
> autosubmit monitor cxxx -o png

Above generated plot with date & time stamp can be found at:

/cfu/autosubmit/cxxx/plot/cxxx_date_time.pdf
or
/cfu/autosubmit/cxxx/plot/cxxx_date_time.png


HOW TO RESTART EXPERIMENT
=========================

> autosubmit recovery -h

> autosubmit recovery cxxx -s # saving the pickle file

> nohup autosubmit run cxxx


FULL DOCUMENTATION AND HOW TOs
