Multiple jobs bug in makefile of FFTW3 interfaces

Lu__You — Wed, 28 Feb 2018 13:18:03 GMT

Dear MKL Team,

I find that the current makefile of the FFTW interfaces, for example, /opt/intel/compilers_and_libraries_2017.4.196/linux/mkl/interfaces/fftw3xf/makefile, do not allow multiple jobs using the -j X command line argument. The bug is minor and it should be easy to fix. The current rule for make lib is:

lib: clean mkresdir $(INSTALL_DIR)/$(INSTALL_LIBNAME) cleanup

which runs a cleanup step in the end. However when one job deletes the folder containing the compiled object files, the rest jobs are still building and will encounter an error. It will be really nice to speed up the build if you could fix this issue. Thank you so much.

Kind regards,

You
