Supported IBM Spectrum LSF versions

IBM Spectrum LSF RTM supports IBM Spectrum LSF 10.1.x.
Note: If you are using LSF 9.1.2 and later, and if you have enabled the security access, then you must add the daemon account of RTM to the ClusterAdmins section of lsf.cluster.clustername. By default, the daemon account is apache (for RedHat) or wwwrun (for SLES). If you do not add these user accounts in lsf.cluster.clustername, then you will not see any data in RTM. Note that the lsf.cluster.clustername file is typically installed in the directory defined by LSF_ENVDIR.

Supported LSF add-ons

  • Dynamic Cluster (Compatibility support): 10.x
  • XL Cluster (Compatibility support): LSF 10.x
  • License Scheduler (Compatibility support): 10.x

Supported local database

RTM supports MariaDB as the local database from the OS distribution. Supported versions are 10.3, 10.5, 10.6, and 10.11.
