Transitioning from the NCSA IBM pSeries 690

NCSA IBM pSeries 690 Retirement Notice
Updates:
- The cap queue will no longer accept job submissions starting at noon CT September 14.
- Jobs that the scheduler calculates will not finish before midnight on September 30th won't be started. This means that as September 30 approaches, submitted jobs have a lesser chance of starting. Based on the current job load, we expect that jobs submitted after September 26 may never get an opportunity to start.
- As of Sept 6 2007, in preparation for copper's impending retirement the wall clock limit on the cap queue has been reduced to 300 hours.
- You can save your copper home directory to a tar file named copperhome.tar in your UniTree account by executing the following command:
```
     cu12% cd $HOME; msscmd "tar cf copperhome.tar ."
```
