Idarm-1 & 2 are 2 ARM Juno r1 development boards (ARM64 bits).

Access to the machines

Example for an interactive access
  oarsub -I -p "machine='idarm'"

Mechanisms to experiments with those ARM Juno machines are different from other digitalis machines (due to a different CPU arch, a different boot process, aso), but they also offer remote control like other machines. We however did not get resources to provide easy multi-user reconfiguration services yet. Please email me if you would like to experiment and require a privileged access to one of those machines for a period of time.

To get a specific machine:

  oarsub -I -p "machine='idarm' and host like 'idarm-2.%'"

Privileged access

Privileged access is granted within exclusive jobs on the juno machines. Please note that any change made to the system (filesystem included, which is on ramdisk) will be lost/reset upon reboot, which automatically happens at the end of jobs for the sake of the sanity of the experimentation environment.


The idarm machines were funded by a Grenoble INP project, led by the Mescal, Moais and Erods teams of of LIG.
