OAR 2.5.3

Release date: 2013-06-25

• Add the “Name” field on the main Monika page. This is easier for the users to find there jobs.
• Add MAX_CONCURRENT_JOB_TERMINATIONS into the oar.conf ofthe master. This limits the number of concurrent processes launched by the Almighty when the the jobs finish.
• Bug fix in ssh key feature in oarsub.
• Added –compact, -c option to oarstat (compact view or array jobs).
• Improvements of the API: media upload from html forms, listing of files, security fixes, add of new configuration options, listing of the scheduled nodes into jobs, fixed bad reinitialization of the limit parameter, stress_factor, accounting… See OAR-DOCUMENTATION-API-USER for more informations.
• CGROUP: handle cgroup hierarchy already mounted by the OS like in Fedora 18 (by systemd in /sys/fs/cgroup) in job_resource_manager_cgroups.pl.
• Bug fix oar-database: fix the reset function for mysql.
• SVG version of drawgantt: all features are now implemented to replace the legacy drawgantt. Both can be installed.
• Bug fix schedulers: rewrite schedulers with placeholders.
• Rework default admission rules.
• Add support to the oar_resource_init command to generate resources with a “thread” property (useful if HyperThreading is activated/used on nodes).
• Fix stdout/stderr bug: check the allowed characters in the path given by the users.
• Fix: the user shell (bash) didn't source /etc/bash.bashrc in batch jobs.
• Add quota which limits the number of used resources at a time depending of the job attributes: queue, project, types, user (available with the scheduler “oar_sched_gantt_with_timesharing_and_fairsharing_and_quotas”).
• Add comments in user job STDERR files to know if a job was killed or checkpointed.
• Add the variable $jobproperties_applied_after_validation. It can be used in an admission rule to add a constraint after the validation of the job. Ex:

        $jobproperties_applied_after_validation = "maintenance='off'";

So, even if all the resources have “maintenance='on'”, the new jobs will be accepted but not scheduled now.

• Add the oardel option –force-terminate-finishing-job: to use when a job is stuck in the Finishing state.
• Bug #15911: Energy saving now waits SCHEDULER_NODE_MANAGER_IDLE_TIME for nodes that have been woken up, even if they didn't run any job.
• Simplify job dependencies: do not check the exit code of the jobs in dependencies.
• Admission rules: add the “estimate_job_nb_resources” function that is useful to know the number of resources that will be used by a job.
• oarstat: add another output format that can be used by using “–format 2” or by setting “OARSTAT_DEFAULT_OUTPUT_FORMAT=2” in oar.conf.
• oarsub: Add the capability to use the tag %jobname% in the STDOUT (-O) and/or STDERR (-E) filenames (like %jobid%).
• bug #14935: fix timesharing jobs within a container issue
• add schedulers with the placeholder feature.

• The OAR database schema version on a fresh database install is bogus (2.5.0 instead of 2.5.2, yes: 2.5.2), which may prevent upgrade to next version to work out of the box. See fix_for_database_schema_version_2.5.0
• OAR 2.5.3 tarball ships with the special file “./”, which causes, if uncompressed as root, to change the ownership of the working directory. This is fixed for next releases.
