+# Sample Slurm job script
+#   for TACC Stampede3 SPR nodes
+#
+#   *** MPI Job in SPR Queue ***
+# 
+# Last revised: 23 April 2024
+#
+# Notes:
+#
+#   -- Launch this script by executing
+#      "sbatch spr.mpi.slurm" on Stampede3 login node.
+#
+#   -- Use ibrun to launch MPI codes on TACC systems.
+#      Do not use mpirun or mpiexec.
+#
+#   -- Max recommended MPI ranks per SPR node: 112
+#      (start small, increase gradually).
+#
+#   -- If you're running out of memory, try running
+#      on more nodes using fewer tasks and/or threads 
+#      per node to give each task access to more memory.
+#
+#   -- Don't worry about task layout.  By default, ibrun
+#      will provide proper affinity and pinning.
+#
+#   -- You should always run out of $SCRATCH.  Your input
+#      files, output files, and exectuable should be 
+#      in the $SCRATCH directory hierarchy.
+#
+#   From Dan,
+#   SPR nodes has 112 cores, however,
+#   try lower cores if you have allocation error in output log.
+#   Especially for large domain case like STOFS-3D 
+#   STOFS-Atl use 85 cores per node
