# ================================================================== #

# Haizea's regular configuration file (the one that is provided

# to the Haizea daemon) allows for, at most, one tracefile to

# be used. However, when running simulations, it is often necessary

# to run through multiple tracefiles in a variety of configurations.

# The "multi-configuration" file allows you to easily do just this.

# It is similar to the regular configuration files (all the options

# are the same), but it allows you to specify multiple tracefiles

# and multiple configuration profiles.

#

# The multi-configuration file must contain a section called "multi"

# where some general options are specified (e.g., the tracefiles you

# want to use). Then, for each section you would ordinarily include

# in a regular configuration file, you can include common options 

# (shared by all profiles) and profile-specific options. For example,

# suppose you want to specify options in the "general" and

# "simulation" sections, and you want to create two profiles

# called "nobackfilling" and "withbackfilling". You would

# have to create the following sections:

#

#   [common:general]

#   ...

#

#   [common:simulation]

#   ...

#

#   [nobackfillingn:general]

#   ...

#

#   [nobackfilling:simulation]

#   ...

#

#   [withbackfilling:general]

#   ...

#

#   [withbackfilling:simulation]

#   ...

#

# Once you've created the multi-configuration file, you must

# feed it into the "haizea-generate-configs" command, which will

# generate a regular configuration file for every combination

# of tracefile and configuration profile. Since running each

# configuration individually would be cumbersome, you can

# also use the "haizea-generate-script" command to generate

# a script that will run through all the generated configuration

# files.

# The following example file uses two example tracefiles, one where

# best-effort leases end prematurely, and one where they don't, and

# two injections of AR leases (with no special characteristic other

# than the fact that the two are different). The file defines

# four configuration profiles:

#

#   - "nobackfilling": best-effort leases are scheduled without

#     backfilling

#   - "backfilling": best-effort leases are scheduled with

#     aggressive backfilling, but without suspend/resume

#   - "backfilling+SR": best-effort leases are schedules with

#     aggressive backfilling and suspend/resume, but without

#     migration.

#   - "backfilling+SR+M": The whole shebang: backfilling, 

#     suspend/resume, and migration.
