Downtime

•

Due to a GPFS file system hang on the fimm frontend, for a short period of time (hopefully 10-15 minutes), the frontend will not be available, all users need to log in again after this.

Update, 10:12: fimm frontend needs to be rebooted to clear the hang.
Update, 10:26: fimm frontend is now rebooted and up again.

•

As previously noted, we will have a scheduled downtime from 16:00 Tuesday July 8th. We will replace a faulty module and do some I/O-benchmarking which requires a reserved system. It is estimated that the machine will be available for login at 19:00.

Update, 16:00: hexagon is shutdown for hw replacement
Update, 16:45: hexagon is up.
Update, 19:10: hexagon is up and allowing users to login.

•

4 compute nodes (1 module) on hexagon have stopped responding and due to this also some of the login nodes and lustre filesystem. We will unfortunately need to reboot hexagon to clear the issue, jobs will need to be re-submitted.

Update 20:30, hexagon is now up again. Note that 4 high-mem nodes are now unavailable due to hardware errors.

•

There will be a planned maintenance on hexagon for software upgrade on Monday June 16th starting at 14:00 and expected to last approximately 3 hours.

The Cray software release will be upgraded from 2.0.44 to 2.0.53.
This release will have more quad-core optimizations as well as a new version of the MPI library. We therefore recommend that you recompile your programs and libraries after the upgrade. We will notify when we have re-compiled the libraries/modules installed by us.

Update 16th, 14:40 System taken down.
Update 16th, 19:30 System back online with version 2.0.53 and MPT 3.0

Look for update on when we have re-compiled libraries:

All compute-node (cnl) software has been re-compiled.
Most login node software has been recompiled, except GNUPLOT.
UPC is not re-compiled yet.
