Hello GlueX,

The newest Haswell farm14 nodes of 2400 cores at JLab have been mostly idle since their installation last fall. That's much of 1.7 M Haswell core-hours each month that are largely unused, or almost 5 M core hours of idle time so far.

Could Hall D keep simulation jobs in the queue and running indefinitely, rather than just during times of the data challenges? Are there other jobs to run? Otherwise, many of the available computing cycles in the farm for Experimental Physics are falling on the floor rather than being used.

Feedback and perspective welcome,
Sandy
