visual studio 2015 supports modules . i'm excited feature, , although know has important implications on , above build time, that's interest right now. i'm thinking of larger code bases of order of half million lines of code or more, have lot of #include s in header files. my previous approach have been manually or automatically remove unnecessary includes in favor of forward declarations, etc, , use precompiled headers. result typically significant improvement in build times, memory of order of 2-3 times. seems should consider using modules, might lot less effort , deliver arguably better engineered , more future-proof solution. can comment potential effect on compile speed of going down module route instead, larger code bases measured in 100s of thousands or millions of lines of code?

i have following python script, create dask dataframe using existing pandas dataframe. i'm using multiprocessing scheduler, since function use pure python. scheduler creates 8 processes (one each partition) running sequentially, 1 @ time. dask_data = ddf.from_pandas(data, npartitions=8) dask_data = dask_data.assign( images_array_1=dask_data.images_array_1.apply(lambda x: [] if x == "" else [int(el) el in x.split(',')], name='images_array_1'), images_array_2=dask_data.images_array_2.apply(lambda x: [] if x == "" else [int(el) el in x.split(',')], name='images_array_2') ) dask_data.compute(get=dask.multiprocessing.get) i'm using dask parallelize computation, dataset small enough stay in main memory. is possible run every process in parallel?
