use HPCI; my $group = HPCI->group(cluster => 'SLURM', ...);
This is a driver module that can be used internally from HPCI, by specifying a cluster type of 'SLURM'. It customizes the HPCI access interface to control jobs submitted to an SLURM (Simple Linux Utility for Resource Management) cluster.
The differences provided by the SLURM driver are:
the following resource names have slurm-specific aliases
Using these aliases causes your code to be SLURM-specific. That makes converting it to use an alternate type of cluster more painful. However, if you do not expect to ever be moving your code to a different cluster type, this might simplify the interface for people who already know the SLURM-specific resource names and wish to avoid the confusion that might come from using the generic names.
a stage attribute native_args_string is available which specifies a string of argument(s) that will be included in the srun/sbatch command that starts execution of that stage
The result information hash returned by
$stats = $group->executeincludes all of the info provided by the SLURM sacct command, not just the exit status.
If a stage is terminated because it exceeds the requested memory resource limit, then it will normally be retried using a higher limit. The default is to first try with '2G' (if no mem resource limit is explicitly specified). After mem failures, the next larger size in the default sequence (2G 4G 8G 16G 32G) is attempted.

Describes the interface common to all HPCI Group objects, regardless of the particular type of cluster that is actually being used to run the stages.
