# Global specifications for BlueGene system
# NOTE: BlueGene/L, P, and Q systems require different Image specifications.
# 	See "man bluegene.conf" for details  This example is for a BGQ system
#	Look at older <=2.3 for examples of L or P
#
# MloaderImage:         MloaderImage used for creation of all bgblocks.
#
# You may add extra images which a user can specify from the srun
# command line (see man srun).  When adding these images you may also add
# a Groups= at the end of the image path to specify which groups can
# use the image.
#
# AltMloaderImage:         Alternative MloaderImage(s).
#
# AllowSubBlockAllocation: This option allows multiple users to
#                          run jobs as small as 1 cnode in size on a block
#                          one midplane in size and smaller.
# LayoutMode:           Mode in which slurm will create blocks:
#                       STATIC:  Use defined non-overlapping bgblocks
#                       OVERLAP: Use defined bgblocks, which may overlap
#                       DYNAMIC: Create bgblocks as needed for each job
# MidplaneNodeCnt:      Number of c-nodes per midplane.
# NodeCardNodeCnt:      Number of c-nodes per node card.
# IONodesPerMP:         Number of I/O nodes per midplane.
#
# BridgeAPILogFile : Pathname of file in which to write the Bridge
#                    API logs.
# BridgeAPIVerbose:  How verbose the Bridge API logs should be
#                    0: Log only error and warning messages
#                    1: Log level 0 and information messasges
#                    2: Log level 1 and basic debug messages
#                    3: Log level 2 and more debug message
#                    4: Log all messages
# DenyPassthrough:   Prevents use of passthrough ports in specific
#                    dimensions, A, X, Y, and/or Z, plus ALL

# Define the static/overlap blocks.  This is ignored and is not needed if
# using dynamic layout mode.
#
# This example assumes NodeName=bg[0000x3233] in the slurm.conf file.
#
# MPs: The midplanes in the block using AXYZ coordinates
# Type:  Connection type "MESH" or "TORUS" or "SMALL", default is "TORUS"
#        Type SMALL will divide a midplane into multiple bgblock
#        based on options NodeCards (count of single node card bglblocks)
#        and Quarters (count of quarter midplane bglblocks) to determine
#        type of small blocks.  With Q you can have each dimension be a
#        different type.  T,T,M,T means torus in all dimensions except the
#        Y dim.
#
# IMPORTANT NOTES:
# * Ordering is very important for laying out switch wires.  Please create
#   blocks with smap, and once done don't change the order of blocks created.
# * A block is implicitly created containing all resources on the system
# * Blocks must not overlap in static mode (except for implicitly
#   created bgblock). This will be the case when smap is used to create
#   a configuration file.
# * All Nodes defined here must also be defined in the slurm.conf file
# * Define only the numeric coordinates of the blocks here. The prefix
#   will be based upon the NodeName defined in slurm.conf.
