 ====== Greentail ======

 On greentail, /sanscratch will be a separate logical volume of 5 TB using a different disk set.  SO i urge those that have very large files to stage their files in /sanscratch when running their jobs for best performance.  The scheduler will always create (and delete!) two directories for you.  The JOBPID of your job is used to create /localscratch/jobpid and /sanscratch/jobpid.
+===== MPI =====
+For those of you running MPI or MPI enabled applications, you will need to make some changes to your scripts.  The ''wrapper'' program to use with greentail's Lava scheduler is the same as for cluster sharptail. It can be found here:  /share/apps/bin/lava.openmpi.mpirun.   If other flavors are desired, you can inform me or look look at the example scripts lava.//mpi_flavor//.mpi[run|exe].
