OAR Syntax simplification

From Grid5000
Jump to: navigation, search

In order to ease the reservation of resources with OAR (using oarsub or the job API), Grid'5000 provides the following mechanisms to simplify the oarsub filters (which otherwise use a regular SQL syntax to select resources):

  • An alias system to translate simple and short keywords to the OAR resource filter expressions (which are often long and complex).
  • The automatic addition of simple quotes for strings (quote still required for text including spaces) in the expressions (e.g. in cluster='yeti' or ib=EDR quotes are not mandatory)
  • The use of short names of nodes instead of the long names which include the grid5000.fr domain name.
  • The use of & alternatively to and; | alternatively to or in OAR resource filter expressions



Aliases are defined for the most common resources, for instance, to ease clusters selection, GPUs, etc. Aliases do not replace the classical way of using the OAR properties. Some of the aliases are site-specific (e.g. cluster and node names).

Aliases must be used within the classical oarsub options: -l and -p.

Here some examples:

Request a node with an SSD
Terminal.png frontend:
oarsub -I -p SSD

Which is equivalent using the regular SQL syntax to:

Terminal.png frontend:
oarsub -I -p "disktype like '%/SSD'"

Request a node with a GTX 1080 Ti Nvidia GPU
Terminal.png frontend:
oarsub -I -p gtx1080ti

Which is equivalent using the regular SQL syntax to:

Terminal.png frontend:
oarsub -I -p "gpu_model='GeForce GTX 1080 Ti'"

Request 2 nodes with an SSD and 256G or more RAM
Terminal.png frontend:
oarsub -I -l nodes=2 -p "ssd&256GB"

Which is equivalent using the regular SQL syntax to:

Terminal.png frontend:
oarsub -I -l nodes=2 -p "disktype like '%/SSD' and memnode >= 262144"
Request a node on grimoire cluster with all its disks
Terminal.png frontend:
oarsub -I -l "{host+disk&grimoire}"/nodes=1

Which is equivalent using the regular SQL syntax to:

Terminal.png frontend:
oarsub -I -l "{(type='default' or type='disk') and cluster='grimoire'}"/nodes=1

Aliases can be mixed with the classical way of requesting resources
Terminal.png frontend:
oarsub -I -p "ib=EDR & 256GB"

Which is equivalent using the regular SQL syntax to:

Terminal.png frontend:
oarsub -I -p "ib='EDR' and memnode >= 262144"

Long node names completion

The automatic completion of short hostnames to add the domain name can be used when filtering with the host property:

For one host
Terminal.png frontend:
oarsub -I -p "host='yeti-1'"

Or even without the quotes:

Terminal.png frontend:
oarsub -I -p "host=yeti-1"

Or since we provide aliases for each node host property, the following also works:

Terminal.png frontend:
oarsub -I -p "yeti-1"

All 3 are equivalent using the regular SQL syntax to:

Terminal.png frontend:
oarsub -I -p "host='yeti-1.grenoble.grid5000.fr'"
For multiple host within an IN()
Terminal.png frontend:
oarsub -I -p "host IN (yeti-1,yeti-2,yeti-3)"

Which is equivalent using the regular SQL syntax to:

Terminal.png frontend:
oarsub -I -p "host IN ('yeti-1.grenoble.grid5000.fr', 'yeti-2.grenoble.grid5000.fr', 'yeti-3.grenoble.grid5000.fr')"

Disabling the syntax simplification

If for any reason you want to disable the syntax simplification in order to just use the OAR regular syntax, it is possible by using the no-syntax-simplifier job type, as follows:

Terminal.png frontend:
oarsub -I -p "cluster='yeti'" -t no-syntax-simplifier
