Commonality in Announcing and Logging Changes
BC Project: FY06-11
Date of Policy: 21 Sep 2009
Last Updated: 21 Oct 2021 (see Revision Log)
This policy defines a time schedule for announcing and logging changes to all user-accessible systems (specifically including allocated HPC systems), networks, important application software, and system support software across all HPCMP centers. Advance notice for announcements of changes to systems accessible to, or that otherwise impact, users are summarized in the table below.
|Any upgrade/change to HPC systems that may affect multiple software packages.
|Any upgrade/change to HPC systems or center's infrastructure that may hinder the effective use of resources at the center.
|Any change must include cases when the centers are determining which versions of software are candidates for removal from the system.
|Any upgrade/change requiring immediate action.
|As early as possible
This policy requires that change announcements provide a summary of the change, impact on users, and other dependencies, such as need to recompile or change scripts or library paths. When possible, a reference to a source of additional information such as a vendor-provided change notice, errata, or other user-oriented documentation should be provided. If the additional information is not directly accessible to users, the information must be provided to the HPC Help Desk, and the announcement shall direct users to the HPC Help Desk for additional information.
All centers are required to use the HPC Help Desk News and Maintenance Tool (NAMT) to submit their announcements. Historical changes, up to one year, can be accessed by the HPC Help Desk in the NAMT archive, and by users on the System News pages on most DSRC websites. Additionally all centers are require to provide an email announcement to users of the system. The email can should be identical to the NAMT posting or point to the NAMT posting for additional information.
