I am unable to attach the configure.log file. Hence. I have copied the
following text after executing the command (less configure.log) in the cygwin64
Executing: uname -s
stdout: CYGWIN_NT-10.0-19044
=
It is in the directory you executed configure in.
Thanks,

I have checked the required Cygwin openmpi libraries and they are all
installed. When I run ./configure --with-cc=mpicc --with-cxx=mpicxx
--with-fc=mpif90, it returns:
$ ./configure --with-cc=mpicc --with-cxx=mpicxx --with-fc=mpif90
Please send the full output when you run with the monitors I mentioned turned
on. If one approach is converging and one is not then we should be able to see
this in differences in the convergence output printed for the two runs getting
further and further apart.

BTW: If you have WSL2 on windows - it might be easier to build/use PETSc.

Make sure you have cygwin openmpi installed [and cywin blas/lapack]
$ cygcheck -cd |grep openmpi

* You could try hypre or another preconditioner that you can afford,
like LU or ASM, that works.
* If this matrix is SPD, you want to use
-fieldsplit_0_pc_gamg_esteig_ksp_type cg
-fieldsplit_0_pc_gamg_esteig_ksp_max_it 10
These will give better eigen estimates, and that is important.
