[Other] Failure 6% of unit test on ubuntu22.04

[MedAdh42]

I have succesfully compiled GEOSX, but after running the unit tests some of them failed

The following tests FAILED:
2 - blt_mpi_smoke (Failed)
110 - testLinearAlgebra_Matrices (Failed)
111 - testLinearAlgebra_Vectors (Failed)
112 - testLinearAlgebra_ExternalSolvers (Failed)
113 - testLinearAlgebra_KrylovSolvers (Failed)
128 - testDofManager (Failed)
129 - testLAIHelperFunctions (Failed)
161 - testNeighborCommunicator_mpi (Failed)
162 - testVTKImport_mpi (Failed)
165 - testHDFParallelFile (Failed)
178 - testDoxygenCheck (Failed)

I've built it on an Ubuntu22.04 virtual machine (running it on windows 11 using Hyper-V), the used compiler GCC (Ubuntu 11.2.0-19ubuntu1) 11.2.0. I should mention that due to some compilation errors I've had to use newer versions of some of the TPLs (see this issue)

Hello @Mohamed-AIDAHI could you send us the logs please?

Also, ubuntu 22.04 is now part of our CI (see #1889) and all the tests are passing.

Here it is.

Looks like it's most often the error message is

128/178 Testing: testDofManager
128/178 Test: testDofManager
Command: "/bin/mpirun" "-n" "2" "/home/ubuntu22/GeosX/GEOSX/build-ubuntu22-release/tests/testDofManager" "-x" "2"

This is a fatal error; mpirun will now abort.  No processes were launched.

Looks like there is a path issue in mpirun? I don't know, but it looks like your installation is at stake?

w.r.t. testDoxygenCheck ther message is

----------------------------------------------------------
error: Problems running latex. Check your installation or look for typos in _formulas.tex and check _formulas.log!
dvips: DVI file can't be opened: _formulas.dvi: No such file or directory
error: Problems running dvips. Check your installation!
<end of output>
Test time =  76.58 sec

which indicates some of the program you may need to install.

Regarding the last failed test (testDoxygencheck) all i needed is to install Latex using : sudo apt install texlive-latex-extra.
As for the the other tests there seems to be an issue parsing the MPI command, according to this issue when the path to mpirun is /bin/mpirun it trims '/bin' leaving a '/' before mpirun which is what MPI is complaining about.

[MedAdh42]

Just as discussed in this issue, when the provided path to the mpirun executable is '/bin/mpirun' the 'A prefix was supplied to mpirun that only contained slashes.' error arises causing mpirun to abort.

I recompiled the code using 'usr/bin/local' as the MPIEXEC path and the problem was solved.

Good news!
