Outage schedule

Webmo at ACENET will be unavailable for use from 8am Nov. 29th to Noon Dec 1st while we upgrade to Webmo 17 which uses HTML5 instead of a Java application. Running jobs will still run and save results in your home directory but may look failed in webmo when it returns to service.

Grid Engine will not schedule any job with a run time (h_rt) that extends into the beginning of a planned outage period. This is so the job will not be terminated prematurely when the system goes down.

  • No cluster outages currently scheduled.


  • The cluster may be unreachable due to an upstream provider networking issue.

  • This morning around 10 am NST (9:30 AST) there was a power outage at Memorial University's St. John’s campus that caused all compute nodes (and jobs running on them) to crash. Almost all nodes are now back online. Grid Engine has automatically restarted jobs that where running at the time of the crash (see also:FAQ#Rr:_Job_re-started).

  • Users report intermittent slowness in interactive use of Glooscap. Symptoms include pauses of several seconds to over a minute in response to shell commands involving files or file metadata (such as "ls"). This is believed to be due to load on the file system, and therefore may also be affecting the run times of jobs doing extensive I/O. Vendor support for the file system is no longer available so deep troubleshooting is out of reach. We have no reports of loss of data or other actual failures. All we can recommend is great patience.
