Change Management

This process primarily targets requests that can be handled with current level of effort (LOE) resources.  This process is also designed to detect and redirect items to the EVMS process if they exceed LOE resources.

Successful changes proceed through 5 stages: 

Open Change Requests

Key	Summary	Process Stage†	Reporter	P	Created	Status
IHS-576	Configure slurm to accept jobs to use only partial nodes	Planning	Tim Morton		02/Nov/17	This change has been approved and is tentatively scheduled for early CY18.
IHS-580	DM developers need a build/test environment that supports docker containers	Feasibility	Joshua Hoblitt		02/Nov/17	Use case and requirements are being gathered. Unknown User (pdomagala) with the PDAC working group last week. They requested further detail on the specifications and timing of the FY18 kubernetes/docker initiative. If that service, even an early implementation, is ready near-term, the need for stop-gap measures may be unnecessary.
IHS-612	Implement debug and normal queues for developers on the verification cluster	Planning	Yusra AlSayyad		16/Nov/17	Currently being planned and tested. Tentatively scheduled for early CY18.
RFC-423	Allow ssh access to verification cluster worker nodes	Feasibility	Simon Krughoff		18/Dec/17	Proposed. 5 days left on comment period.
