We've tried
@Barry : Perahps config/BuildSystem/config/packages/fftw.py should use the
--host option when configure for PETSc is run with-batch=1.
If anyone here knows what --host must be set to for KNL, I'd appreciate it.
PS : I know that Intel-MKL-FFT provides FFTW api. If I'd want to try with
this, is
Hi Barry,
fftw-configure fails on login node. I'm attaching the error message at the
bottom of this email. I tried request 1 hour of time on a compute node to
compile fftw on it but for some reason 1 hour is not enough to compile
fftw, hence I was forced to use cray-fftw-3.3.8.1 for which I had
I assume the example runs fine with --download-fftw on theta?
Is the cray-fftw-3.3.8.1 compatible with the MPI you are using?
Perhaps the cray-fftw-3.3.8.1 assumes extra padding in the array lengths
then standard fftw. You could add some extra length to the arrays allocated by
PETSc
Hi PETSc-developers,
I'm trying to run ex143 on a cluster (alcf-theta). I compiled PETSc on
login node with cray-fftw-3.3.8.1 and there was no error in either
configure or make.
When I try running ex143 with 1 MPI rank on compute node, everything works
fine but with 2 MPI ranks, it crashes due
