Hi Shriram,

Thank you for your question. CAS does not replace SAS Grid Manager generally nor does CAS replace LSF specifically. Our plan is to make SAS Grid Manager available on the Viya architecture. Where SAS Grid Manager leverages the SAS Metadata Server and mid-tier services in SAS 9 it will leverage microservices on the Viya architecture.

SAS Viya has multiple compute engines:
- CAS
- Traditional SAS (referred to as the SAS Programming and Run-Time Engine)
- The SAS Event Stream Processor
- In-Database engines

As a server and compute engine CAS offers some prioritization of resource utilization between different user groups but it does not provide workload management.

As SAS 9 customers move more functionality to Viya based SAS products it is reasonable that they expect that traditional SAS jobs and batch flows would continue to function - including the ability to launch work on the least busy node in the environment; The ability to prioritize work and target compute resources via queues; The ability to monitor and restart services; etc. Bringing SAS Grid Manager to Viya will provide all of these capabilities and will enhance Viya based SAS offerings to include some of these features that are not currently available.

SAS introduced our own grid provider (SAS Workload Orchestrator) in SAS 9.4m6. SAS Workload Orchestrator will be a functional alternative to LSF for Viya based deployments as well.
