…into next (PR #6402) Remove the exclusive directive from the batch files for all NERSC machines. The reason we want to do this: a) no longer needed (in fact default) b) it allows a user to use --qos shared when desired (and there is no flag to turn off exclusive) Note that using -q shared or --qos shared allows a job to share resources with other jobs on the node. The advantage is that jobs using shared are not charged as much as a full node. There will be no performance impact. [bfb]

After #6402 removed exclusive directive, which allows jobs to use shared qos, I realized we still needed the option to use shared qos. This PR should allow: ./xmlchange JOB_QUEUE=shared I also adjusted the total number of nodes available for each machine. [bfb]
