No login node is intel-broadwell and compute node is intel-skylake. Problem is
that the supercomputer I am compiling on has no way to access compute node
(interactive job) directly for compiling. I am not sure if dealii allows for
cross compilation.
I've never tried that. Maybe Martin has experience with that?
Unfortunately nothing that would help - I always managed to run at least
the configuration (cmake) on the same architecture whereas I indeed
built (make) on a different architecture once the compilation was
finished through and with a fixed '-march=knl' for example. But we
should definitely support cross-compilation. I'm not sure how our
support was - I will test this before the release.
As to the present case: Phani, have you tried to submit the compilation
job, i.e., "cmake -D .... && make -j xx" through a job file? That should
invoke the right microarchitecture; some machines do not have all
compile tools such as cmake available as modules on the nodes, though.
Best,
Martin
