open TELEMAC-MASCARET The mathematically superior suite of solvers

Greetings.

I am getting the following error, when I run an exercise .cas with variable PARALLEL PROCESSORS = 4.

Parallel Incongruence:
+> you may be using an inappropriate configuration: gfortran.
+> or may be wanting scalar mode while setting to 4 processors.

The operating system where Telemac is compiled is "CentOS Linux release 7.9.2009 (Core)" and the Telemac version is "v8p2r0".

I appreciate your help.

The log indicates that you are using the "gfortran" configuration, when you should be using the gfortranHPC configuration to have MPI support. However, since the USETELCFG environment variable in your pysource.gfortranHPC.txt file is correct (it should be named with a ".sh" extension, by the way), you probably sourced the wrong pysource script.

As a side note, the version set in your systel configuration file (v8p1) does not match the version you are using (v8p2).
