Reduce logfile output in HEMCO, and combine Verbose and Warnings into a single switch #182

yantosca · 2022-12-06T22:12:43Z

This is the PR corresponding to issue #180 and to geoschem/geos-chem#1549.

In this PR we seek to:

Convert most HEMCO logfile output to debug-only printout
Consolidate Verbose and Warnings into a single logical switch in HEMCO_Config.rc (e.g. Verbose: true) so that warnings will also be toggled by Verbose. There isn't much need for separate verbose & warnings levels any more.

src/Core/hcoio_read_std_mod.F90 - Change warnlev from 1 to 2 in the call to HCO_Warning. This will only print the "data is treated as unitless" warning if "Warnings: 2" is defined in HEMCO_Config.rc. - TODO: Combine Verbose and Warnings into a single logical toggle. Signed-off-by: Bob Yantosca <[email protected]>

src/Core/hco_error_mod.F90 - Define HCO_IsVerb as an interface of 2 overloaded subroutines (one that takes the VerbNr argument and one that does not). This will facilitate combining the Verbose and Warnings toggles into a single logical switch. - The HCO_IsVerb* routines have been rewritten to avoid ELSE statements, which is more computationally efficient. - Routine HCO_MsgErr now will only print the passed string if Verbose >= 3. - Also use WRITE( 6, '(a)' ) statements instead of PRINT*, so as to line up the printout with the first column. - Cosmetic changes Signed-off-by: Bob Yantosca <[email protected]>

We have changed calls to HCO_IsVerb( HcoState%Config%Err, 3 ) HCO_IsVerb( HcoState%Config%Err, 2 ) HCO_IsVerb( HcoState%Config%Err, 1 ) to HCO_IsVerb( HcoState%Config%Err ) because we now use a logical on/off (stored in Err%doVerbose) to toggle verbose output instead of the numerical levels.

Also tagging @jimmielin. Long story short, we changed "Verbose" and "Warnings" to a single "Verbose: true" flag to toggle debug output. I didn't touch the CESM config files but maybe I should. When you have time, could let us know if you see anything that would break CESM-GC functionality?

TL;DR:

When reading each line from HEMCO_Config.rc, it checks to see if Verbose is logical (t, T, f, F in the same line with Verbose) or not.
If Verbose is logical, then we get the value of Verbose into a logical variable doVerbose. We then print a message about whether or not verbose output is on.
If Verbose is not logical, then try to read the integer values of Verbose and, if necessary Warnings. If either of these are nonzero, verbose output will be turned on. We print a message about the status of verbose output (on/off) and then also a note about the integer values being deprecated.

I ran a bunch of tests with the various settings of Verbose and Warnings, and show the message that is printed out.

-----------------------------------------------------------------------------------
Verbose:                     0
Warnings:                    0

HEMCO verbose output is OFF.
Numbered Verbose and Warning options are deprecated.
Please use "Verbose: true:" or "Verbose: false" for controlling verbose output.

-----------------------------------------------------------------------------------
Verbose:                     1
Warnings:                    0

HEMCO verbose output is ON.
Numbered Verbose and Warning options are deprecated.
Please use "Verbose: true:" or "Verbose: false" for controlling verbose output.

-----------------------------------------------------------------------------------
Verbose:                     2
Warnings:                    0

HEMCO verbose output is ON.
Numbered Verbose and Warning options are deprecated.
Please use "Verbose: true:" or "Verbose: false" for controlling verbose output.

-----------------------------------------------------------------------------------
Verbose:                     3
Warnings:                    0

HEMCO verbose output is ON.
Numbered Verbose and Warning options are deprecated.
Please use "Verbose: true:" or "Verbose: false" for controlling verbose output.

-----------------------------------------------------------------------------------
Verbose:                     0
Warnings:                    1

HEMCO verbose output is ON.
Numbered Verbose and Warning options are deprecated.
Please use "Verbose: true:" or "Verbose: false" for controlling verbose output.

-----------------------------------------------------------------------------------
Verbose:                     0
Warnings:                    2

HEMCO verbose output is ON.
Numbered Verbose and Warning options are deprecated.
Please use "Verbose: true:" or "Verbose: false" for controlling verbose output.


-----------------------------------------------------------------------------------
Verbose:                     true

HEMCO verbose output is ON

-----------------------------------------------------------------------------------
Verbose:                     false

HEMCO verbose output is OFF

-----------------------------------------------------------------------------------
no verbose in HEMCO_Config.rc

HEMCO verbose output is OFF

-----------------------------------------------------------------------------------

So I think this should be OK.

NOTE: I had to pre-determine whether Verbose is logical or not in order to avoid runtime read errors (i.e. reading integer values and getting characters, etc.)

I have removed much of the prior logic in commits 824b07f and 78238df.

Also, in commit geoschem/geos-chem@0df54f6 I have added the VerboseOnCores setting to allow users to specify if they would like to send verbose output to the root core or to all cores (analogous to GEOS-Chem).
