unrecognised option at configure
DGCaprace opened this issue · comments
Hi,
I would like to use the recommended --enable-oned --enable-stride1
options, as advertised in the documentation, when configuring the install of the library. However, I get the following warning when executing the configure script:
configure: WARNING: unrecognized options: --enable-oned, --enable-stride1
Are these options ignored? deprecated? or have they been made default and one doesn't need to specify them?
Hi Dr. Pekurovski,
Thanks for the quick reply: I was referring to the table of arguments on the install page of the online readthedoc of P3DFFT++ which still has these options, to date. Then, could you please confirm that P3DFFT v3 always use stride-1 accesses in the calls to FFTW? Same question for --enable-useeven: are you always padding in order to call MPI_Alltoall
instead of MPI_Alltoallv
?
