IBM Spectrum LSF Manageable-Resources: SMT Mode + GPU Compte Mode

See this idea on ideas.ibm.com

IBM Spectrum LSF has a view on several types of resources representing the configuration of the managed Compute Nodes.

For instance, LSF has a view on :

- The total number of CPUs available on nodes.

- The number of GPUs available on nodes, as well as their Compute Mode (Default, Prohibited, Exclusive, Shared).

Based on these informations, LSF can determine whether a user workload would fit on a given Compute Node, depending on the specific requirements for the job.

The issue here is that these two specific types of resources are somehow "manageable", in the sense that:

- The total number of CPUs available depends on the SMT mode, and can vary from 20 (SMT=off) to 160 (SMT=8) (example taken from IBM Power System S822LC).

- The Compute Mode of the GPUs can be easily changed, and most of the time, there is no reason why this should be fixed forever.

So we have here two kinds of resources that LSF could act upon in order to change the Compute Node configuration and make it match the workload requirements.
