 ### Changed
 
+- Added commandline options to `checkpoint_benchmark.x` and `restart_benchmark.x` to allow for easier testing of different configurations. Note that the old configuration file style of input is allowed via the `--config_file` option (which overrides any other command line options)
 - Update ESMF version for Baselibs to match that of Spack for consistency
 - Update `components.yaml`
   - ESMA_env v4.32.0

 This benchmark simulates writing a series of 3D variables of a given cubed-sphere resolution to a file using the same strategies as used by the real checkpoint code in MAPL
 
-The code has the following options and needs an ESMF rc file named checkpoint\_benchmark.rc

+NOTE 1: If you specify a `config_file` it must be an ESMF Config file with the following options:
 
 - "NX:" the x distribution for each face
 - "NY:" the y distribution for each face
 - "IM\_WORLD:" the cube resolution
 - "LM:" the number of levels
 - "NUM\_WRITERS:" the number of writing processes either to a single or independent files
 - "NUM\_ARRAYS:" the number of 3D variables to write to the file
-- "CHUNK:" whether to chunk, default true
-- "GATHER\_3D:" gather all levels at once (default is false which means a level at a time is gathered)
-- "SPLIT\_FILE:" default false, if true, each writer writes to and independent file
-- "WRITE\_BARRIER:" default false, add a barrier before each write to for synchronization
-- "DO\_WRITES:" default true, if false skips writing (so just an mpi test at that point)
-- "NTRIALS:" default 1, the number of trials to make writing
-- "RANDOM\_DATA:" default true, if true will arrays with random data, if false sets the array to the rank of the process
+- "CHUNK:" whether to chunk, default `.true.`
+- "GATHER\_3D:" gather all levels at once (default is `.false.` which means a level at a time is gathered)
+- "SPLIT\_FILE:" default `.false.`, if `.true.`, each writer writes to and independent file
+- "WRITE\_BARRIER:" default `.false.`, add a barrier before each write to for synchronization
+- "DO\_WRITES:" default `.true.`, if `.false.` skips writing (so just an mpi test at that point)
+- "NTRIALS:" default 3, the number of trials to make writing
+- "RANDOM\_DATA:" default `.true.`, if `.true.` will arrays with random data, if `.false.` sets the array to the rank of the process
 
-Note that whatever you set NX and NY to the program must be run on `6*NX*NY` processors and the number of writers must evenly divide `6*NY`
