Support of the video wall falls under the HPC analyst’s responsibilities (currently Sylvain Korzennik, hpc@cfa) and is managed following this Management Policy (PDF version).
While Sylvain was responsible for the system design, and is responsible for troubleshooting issues as they arise, as well as for issuing, renewing, and managing credentials, he is not available to provide immediate support.
Some of the library (and the CF) staff are well-versed in the use of the video wall. If needed, and requested in a timely manner, they can and will provide support. They, in turn, will request Sylvain’s assitance if and when deemed necessary.
