+# This is the default hostfile for Open MPI.  Notice that it does not
+# contain any hosts (not even localhost).  This file should only
+# contain hosts if a system administrator wants users to always have
+# the same set of default hosts, and is not using a batch scheduler
+# (such as SLURM, PBS, etc.).
+#
+# Note that this file is *not* used when running in "managed"
+# environments (e.g., running in a job under a job scheduler, such as
+# SLURM or PBS / Torque).
+#
+# If you are primarily interested in running Open MPI on one node, you
+# should *not* simply list "localhost" in here (contrary to prior MPI
+# implementations, such as LAM/MPI).  A localhost-only node list is
+# created by the RAS component named "localhost" if no other RAS
+# components were able to find any hosts to run on (this behavior can
+# be disabled by excluding the localhost RAS component by specifying
+# the value "^localhost" [without the quotes] to the "ras" MCA
+# parameter).
