Ok, looking forward to jedi master's advice ! :)
By the way, I installed and ran the same project on (1) another macOS system,
my laptop, and (2) a Google Cloud 'HiCPU' Ubuntu VM. I added the setup
commands
in the same repo under 'gcp_commands.sh'. It is quite simple in fact. I wanted
to compare the perfs: Added the result at the bottom of the README.
A few feedbacks:
you're pointing at an obsolete pythran.cfg as base reference which leads to a
few unnecessary lines. It's usually not needed to customize all fields, only
the one you change. In your case
[compiler]
cflags=-std=c++11 -fno-math-errno -w -I/usr/local/opt/llvm/include # not
quite sure why you need that though
ldflags=-L/usr/local/opt/llvm/lib # added
CC=/usr/local/opt/llvm/bin/clang # added
CXX=/usr/local/opt/llvm/bin/clang++ # added
should be enough
Concerning your #pythran export, a quick look at the call site makes me think
you could use a numpy array instead of a list, thus saving extra conversion
time.
I'm curious about the openmp crash... I'll try to reproduce it on Linux.
