UPDATE: Hydra Cluster : Login Node under Emergency Maintenance

Dear Hydra users,

we are preparing node tera.tamu.edu to host the interactive login sessions for Hydra. We believe that this new interactive node will get on-line before the end of the day.

The node which crashed (f1n9 or hydra1.tamu.edu) was playing a number of different roles, including, GPFS I/O server, alternate LL scheduler and interactive host. Its abrupt crashing has created some confusion to LL as to which jobs are still active or not. LL may have to be restarted to clear stale state information for jobs. Some of the jobs will have to be resubmitted.
