AWS ParallelCluster v3.7.0

We're excited to announce the release of AWS ParallelCluster Node 3.7.0

This is associated with AWS ParallelCluster v3.7.0

CHANGES

• Perform default job-level scaling for exclusive jobs, by reading job information from SLURM_RESUME_FILE.
• Make aws-parallelcluster-node daemons handle only ParallelCluster-managed Slurm partitions.

BUG FIXES

• Fix an issue that was causing misalignment of compute nodes DNS name on instances with multiple network interfaces,
  when using SlurmSettings/Dns/UseEc2Hostnames equals to True.

AWS ParallelCluster v3.6.1

We're excited to announce the release of AWS ParallelCluster Node 3.6.1

This is associated with AWS ParallelCluster v3.6.1

CHANGES

• Avoid duplication of nodes seen by ClusterManager if compute nodes are added to multiple Slurm partitions.

BUG FIXES

• Fix fast insufficient capacity fail-over logic when using Multiple Instance Types and no instances are returned.

AWS ParallelCluster v3.6.0

We're excited to announce the release of AWS ParallelCluster Node 3.6.0

This is associated with AWS ParallelCluster v3.6.0

CHANGES

• Consider dynamic nodes failing Slurm registration, identified by INVALID_REG flag, as bootstrap failure towards the Slurm protected mode.
  Static nodes failing the Slurm registration are already treated as a bootstrap failure after the node_replacement_timeout.

BUG FIXES

• Fix an issue that was causing misalignment of compute nodes IP on instances with multiple network interfaces.

This is associated with AWS ParallelCluster v3.5.0

ENHANCEMENTS

• Add logging of compute node console output to CloudWatch from head node on compute node bootstrap failure.
• Add validators to prevent malicious string injection while calling the subprocess module.

BUG FIXES

• Fix an issue in clustermgtd that caused compute nodes rebooted via Slurm to be replaced if the EC2 instance status checks fail.

CHANGES

• Do not consider dynamic nodes in IDLE+CLOUD+COMPLETING+POWER_DOWN+NOT_RESPONDING as unhealthy anymore.
  • The root cause has been fixed in Slurm 22.05.6.
