Hi, the tool is the free Oracle Solaris Studio Performance Analyzer. I like it for its nice graphical output even when you use different compilers. It is compatible with OpenMPI...

What would be useful, if you got the profiler going and FFTW having `-ggdb`, would be to try the `pfft/tests/openmp/simple_check_c2c_omp.c` with larger array size (I used 512) and appropriate number...

Just to add that an equivalent in pure FFTW3 is running properly. I am not sure if this is a regression, but I think my program used to work with...

I used stock FFTW 3.3.4. One of the computers has pfft commit cd4619163026e8d14b8b1e097aa214ae9311f52c. It doesn't crash with less processes.

Yes, I am. I have multiple versions of OpenMPI in different modules, but I have various libraries compiled for OpenMPI 2 and I would have to recompile everything when switching...

OK, there were some issues with OpenMPI 2 and I actually realized my own software was actually compiled with OpenMPI 3, but after switching the modules the results are virtually...

Not sure if I got PETSc to compile. It is quite unfortunate I have to do it in the first place as Linux distributions do have PETSc and MUMPS available...

I think `implicit none` can be omitted for procedures which get `implicit none` from their host, both internal and module procedures. At least that is my personal style and I...

There are some tricks for poor man's templates where instead of C macros one can use implicit typing and standard include statement. consider ``` #define mytype type(abc) subroutine abc_sub #include...

My practice is to add the name after the `end subroutine` if the subroutine gets longer than one page in my editor. It's a subjective criterion and sometimes I forget...
