Lauren informed me yesterday that some of the systems were booting into
the parallel cluster environment (asgard) instead of compscience.   This
means that most of you will not be able to log in.   However -- this
should be easily fixable. 

When the systems are booting into linux and you see the blue bar
starting to progress across the bottom of the screen, hit the <ESC>
key.  This will show you the boot process as it loads modules, drivers,
disks, etc.   You will most likely see something like this come up on
the screen.

************************************************************
* This system is going to boot into the Olympus Parallel   *
* Computing Cluster domain.  If you want to boot into      *
* the Computer Science domain, hit any key.                *
************************************************************

You have 5 seconds to hit any key to cause it to boot into the computer
science domain.  So hit a key and you should be okay.


Also, you will probably want to utilize the gcc 6.4.0 compiler suite
like the one we have set up in Godsey.  You will need to modify your
.bash_profile to use this effectively.  I recommend adding something
like the following to your .bash_profile so it will only reconfigure the
path for the CSC 200 systems.


HOSTCLASS=$(hostname -f | cut -b -6)
if [ "$HOSTCLASS" = "csc200" ]; then
    export PATH=/usr/local/gcc/6.4.0/bin:${PATH}:.
    export LD_LIBRARY_PATH=/usr/local/gcc/6.4.0/lib64:${LD_LIBRARY_PATH}
    export MANPATH=/usr/local/gcc/6.4.0/share/man:${MANPATH}
fi
