BUG FIXES

2.6.1

ENHANCEMENTS

  • Change ProctrackType from proctrack/gpid to proctrack/cgroup in slurm.conf in order to better handle termination of stray processes when running MPI applications. This also includes the creation of a cgroup Slurm configuration in in order to enable the cgroup plugin.
  • Skip execution, at node bootstrap time, of all those install recipes that are already applied at AMI creation time. The old behaviour can be restored setting the property "skip_install_recipes" to "no" through extra_json. The old behaviour is required in case a custom_node_package is specified and could be needed in case custom_cookbook is used (depending or not if the custom cookbook contains changes into any *_install recipes)
  • Start CloudWatch agent earlier in the node bootstrapping phase so that cookbook execution failures are correctly uploaded and are available for troubleshooting.

CHANGES

  • FSx Lustre: remove x-systemd.requires=lnet.service from mount options in order to rely on default lnet setup provided by Lustre.
  • Enforce Packer version to be >= 1.4.0 when building an AMI. This is also required for customers using pcluster createami command.
  • Remove /tmp/proxy.sh file. Proxy configuration is now written into /etc/profile.d/proxy.sh
  • Omit cfn-init-cmd and cfn-wire from the files stored in CloudWatch logs.

  • Changes to sshd config:

2.4.1

ENHANCEMENTS

  • Install IntelMPI on Alinux, Centos 7 and Ubuntu 1604
  • Upgrade EFA to version 1.4.1
  • Run all node daemons and cookbook recipes in isolated Python virtualenvs. This allows our code to always run with the required Python dependencies and solves all conflicts and runtime failures that were being caused by user packages installed in the system Python

CHANGES

  • Torque: upgrade to version 6.1.2
  • Run all node daemons with Python 3.6
  • Torque: changed following parameters in global configuration:
    • server node_check_rate = 120 - Specifies the minimum duration (in seconds) that a node can fail to send a status update before being marked down by the pbs_server daemon. Previously was 600. This reduces scaling reaction times in case of instance failure or unexpected termination (especially with spot)
    • server node_ping_rate = 60 - Specifies the maximum interval (in seconds) between successive "pings" sent from the pbs_server daemon to the pbs_mom daemon to determine node/daemon health. Previously was 300. Setting it to half the node_check_rate.
    • server timeout_for_job_delete = 30 - The specific timeout used when deleting jobs because the node they are executing on is being deleted. Previously was 120. This prevents job deletion to hang for more than 30 seconds when the node they are running on is being deleted.
    • server timeout_for_job_requeue = 30 - The specific timeout used when requeuing jobs because the node they are executing on is being deleted. Previously was 120. This prevents node deletion to hang for more than 30 seconds when a job cannot be rescheduled.

BUG FIXES

  • Restore correct value for filehandle_limit that was getting reset when setting memory_limit for EFA
  • Torque: fix configuration of server operators that was preventing compute nodes from disabling themselves before termination

2.4.0

ENHANCEMENTS

  • Add support for EFA on Centos 7, Amazon Linux and Ubuntu 1604
  • Add support for Ubuntu in China region cn-northwest-1

CHANGES

  • SGE: changed following parameters in global configuration
    • max_unheard 00:03:00: allows a faster reaction in case of faulty nodes
    • reschedule_unknown 00:00:30: enables rescheduling of jobs running on failing nodes
    • qmaster_params ENABLE_FORCED_QDEL_IF_UNKNOWN: forces job deletion on unresponsive nodes
    • qmaster_params ENABLE_RESCHEDULE_KILL: forces rescheduling or killing of jobs running on failing nodes
  • Slurm: decrease SlurmdTimeout to 120 seconds to speed up replacement of faulty nodes
  • Always use full master FQDN when mounting NFS on compute nodes. This solves some issues occurring with some networking setups and custom DNS configurations
  • Set soft and hard ulimit on open files to 10000 for all supported OSs
  • Pin python supervisor version to 3.4.0
