Parallel configuration test error in Dynare

Installation and Setup
1

Hi.
I wrote a configuration file for parallel computation of a model. When I test this configuration file in MATLAB unfortunately I have an error.

dynare modelname parallel_test conffile=myconf.ini

The error is ‘command_string’

I think that these is a mistake in typing of configuration file. I checked it but the problem isn’t solved.My configuration file is very similar to a normal configuration file in Dynare.

Please provide the full error message and the conffile you are using.

Configuration file content:

[cluster]
Name=Local
Members=n1

[node]
Name=n1
ComputerName=localhost
CPUnbr=2

Error content is as follows:

Testing computer -> localhost <- …

Check on Local Variable … Ok!

Checking Hardware please wait …
The command causing the error was:
Undefined function or variable ‘command_string’.

Error in AnalyseComputationalEnvironment (line 559)
disp(command_string)

Error in RBC_MA2020.driver (line 166)
ErrorCode = AnalyseComputationalEnvironment(options_.parallel,
options_.parallel_info);

Error in dynare (line 293)
evalin(‘base’,[fname ‘.driver’]) ;

This is due to a bug. The fix is at https://git.dynare.org/Dynare/dynare/-/merge_requests/1758

Thanks so much professor.
I fixed the bug and the problem solved completely but not only due to bug fix but also it needed some other changes on windows configuration with pstools.

But I should indicate that parallel computation of a model in Dynare was interesting for me.
