The Experimental workflow
The workflow consists of these steps:
- book nodes by submitting a job to the OAR scheduler
- submit experimental tasks, with Minus
Book nodes with //OAR//
Only one person can use the whole CorteXlab testbed at the same time. The OAR scheduler is used to book nodes on the platform. As soon as you book one or more nodes, the CorteXlab room is reserved for your usage.
The role of OAR is to schedule node reservations. It manages jobs associated with users, which has a start time, a duration (walltime), and uses some resources (CorteXlab nodes).
The principle of operation of CorteXlab is that users submit jobs to OAR. When the job starts, the user gets exclusive access to the platform, and inside an OAR job, the user can perform (interactively, or in batch) one or several experiments.
A basic example to submit an OAR interactive job requesting all available nodes:
