making Sage the main "driver" calling your code wrapped as a Cython extension would another option, probably faster and certainly easier to implement than an embedded python. In particular, if the main part of your code is already a dynamic library, this would be not much extra coding... > > > > > On Jan 10, 2018 23:54, "Jori Mäntysalo" <jori.ma...@uta.fi <javascript:>> > wrote: > > On Wed, 10 Jan 2018, Berkeley Churchill wrote: > > (@Jori: unfortunately starting one process and doing all the computations >> at once won't work for us because we need to dynamically generate the n+1st >> computation based on the output of the nth computation.
