aws-parallelcluster-node CHANGELOG

This file is used to list changes made in each version of the aws-parallelcluster-node package.

CHANGES

  • nodewatcher: sge - improve logic to detect if a compute node has running jobs
  • sqswatcher: remove invalid messages from SQS queue in order to process remaining messages
  • sqswatcher: add number of slots to the log of torque scheduler
