Hello
I am new to ABINIT and I have some questions about the input and output files. Question is I would like to ask about a warning that appears in the log file for calculations using a parallel version of abinit 7.0.5:

getng.F90:199:WARNING
The second and third dimension of the FFT grid, 0 0 were imposed to be multiple of the number of processors for the FFT, 1
For input ecut= 9.990000E+00 best grid ngfft= 108 108 40
max ecut= 1.016626E+01

==== FFT mesh ====
FFT mesh divisions ........................ 108 108 40
Augmented FFT divisions ................... 109 109 40
FFT algorithm ............................. 401
FFT cache size ............................ 16
getmpw: optimal value of mpw= 5428

Thank you in advance for any help.
