Shaheen-I job size limitation

We only have a limited number of spare parts for Shaheen, and yesterday we exhausted our stock of node cards.

We have had another node card failure this morning, which means that we are now in the situation where we are ‘cannibalising’ the system to supply parts.

With immediate effect we have taken two node cards offline in rack 00.

This means that we can no longer run 16 rack jobs and the maximum size job that can be run on Shaheen is now 12288 nodes (12 racks).

Tip of the Week: Using TotalView Debugger for Parallel jobs on Neser

In this example, we will be using the Intel compiler along with OpenMPI/1.6.4/intel( intel-compilers/11.1 and openmpi/1.6.4/intel should be loaded). In addition, it is required that you connect to Neser using the ssh –X option, to get the Totalview GUI ( Graphical User Interface).

Disruption to Shaheen earlier today

Earlier today, a fault occurred on both Shaheen front end nodes, rendering them completely unresponsive. To remedy the situation, both front end nodes were rebooted. We apologise for any disruption this may have caused. The root cause of the problem is still under investigation.

Maintenance Session Tuesday 17th February

The next maintenance session will be on Tuesday 17th February from 12:00 until 17:00. There will be no access to the system during this period.
