Hi Devs,
I am building from source and had a few questions.
-
MAX_JOBS
env var doesn’t seem to have any effect on parallel compile. htop shows activity on <10% of cores throughout build process. -
I am using following command to inject “-O3” flag in setup.py parameters. (My objective is to unroll and vectorize loops for a 64-core/256HT CPU.)
sed -i ‘s/'-Wno-write-strings'/'-Wno-write-strings' , '-O3'/’ setup.py
Is there an environment variable I can use to specify optimization flags? I can submit a pull request to add such a flag if you’d like because sed method is brittle.
- MKL libraries are in conda3/pkgs/mkl-2018.0.0-hb491cac_4/lib/ folder, but not being detected during build. Does MKL detection rely on
CMAKE_LIBRARY_PATH
env var, or something else?
Thanks!
