+===== Setting Environmental Variables =====
+If you would like to change your shell to bash, make a file called .profile which you will put all of your environmental settings into, and add this to the beginning:
-===== Directory structure =====
+  if [ "$SHELL" = "/bin/sh" ]
-  * Root: /campusdata/BME235
+  then
-  * [[/bin|/bin]]
+        SHELL=/bin/bash
-  * [[/bin/x86_64|/bin/x86_64]]
+        export SHELL
-  * [[/bin/scripts|/bin/scripts]]
+  fi
-  * [[/data|/data]]
-  * [[/programs|/programs]]
-  * [[/lib|/lib]] (renamed from libs to lib to simplify install process so you can install most programs with --prefix=/campusdata/BME235) --- //[[jstjohn@soe.ucsc.edu|John St. John]] 2010/04/06 23:56//
+If you would like to add our classes bin directory (or any other directory for that matter) then add this to your .profile:
-  * [[/include|/include]] (currently contains boost headers)
-  * [[/experiments|/experiments]]
+  PATH=/campusdata/BME235/bin:$PATH
+  export PATH
+To use the gcc-4.5 family of compilers stored in our bin directory then you can specify the LD_LIBRARY_PATH environmental variable:
+  LD_LIBRARY_PATH=/campusdata/BME235/lib:/campusdata/BME235/lib64:$LD_LIBRARY_PATH
+  export LD_LIBRARY_PATH
+To make your default folder creation settings group readable and writable then add this line to your .profile:
+  umask 007
+===== Sungrid Job scheduler =====
+Campusrocks uses sungrid for scheduling jobs.  The techstaff request that jobs only be run
+on the compute nodes, not the head node, as jobs run there slow down the entire cluster.
+They threaten to kill jobs found running on the head node.
+There is [[http://campusrocks.soe.ucsc.edu/roll-documentation/sge/5.2/|Online documentation]] of how to use sungrid to submit jobs on the cluster.  The main commands are
+  * qsub: Submits a job (create a shell script, then run "qsub -cwd shellscript")
+  * qdel: Delete a job
+  * qlogin: Interactive login
+  * qstat: See the status of jobs in the queue
+  * qmon: Graphical User Interface (GUI)
+The web site is locked so that it can only be accessed oncampus.
+[[http://web.njit.edu/topics/HPC/basement/sge/SGE.html|SunGrid Quick Start]]
+Useful submit-script settings for SGE:
+#$ -N some_name_here\\
+Apparently, you must have a single word after -N\\
+This gives a nicer name to your script when you run qstat.\\
+#$ -V\\
+Your jobs use **your** environment variables.
