OpenPBS is a highly configurable open source workload manager. See the OpenPBS project site for an overview and the PBSpro documentation for more information on using, configuring, and troubleshooting OpenPBS in general.
OpenPBS (formerly PBS Professional OSS) is released as part of version 20.0.0. PBSPro OSS is still available
in CycleCloud by specifying the PBSPro OSS version.
[[[configuration]]]
pbspro.version = 18.1.4-0In order to try and ensure that the correct VMs are provisioned for different types of jobs, CycleCloud treats autoscale of MPI and serial jobs differently in OpenPBS clusters.
For serial jobs, multiple VM scalesets (VMSS) are used in order to scale as quickly as possible. For MPI jobs to use the InfiniBand fabric for those instances that support it, all of the nodes allocated to the job have to be deployed in the same VMSS. Currently, a single VMSS is used for all MPI jobs. This can occasionally lead to slower provisioning and deprovisioning of nodes since VMSS operations are atomic. If the scaleset is waiting on some nodes to deprovision, CycleCloud must wait for that operation to complete to provision more nodes.
