Hi Alan!
Indeed, parallelism is another avenue. SymEngine can be compiled in a
"thread-safe" mode, which enables to then use it in parallel. It's slightly
slower, since the reference counted pointer becomes an atomic (so the idea
below about not using reference counted pointers might help here
For speed up how about parallel processing? Looking at Ryzen processors
16 cores and 32 threads are quite affordable these days. Is parallel
python mature code these days?

Hi,
I am CCing the symengine list also. Let me say a few words about the design and
goals of SymEngine. It's a result of many years of experience with SymPy and
implementing high performance code in general. The goal is the fastest possible
symbolic manipulation. So we do not want to introduce
I think the only way is to move SymPy away from its current approach
of automatically evaluating things when expressions are constructed.
To take a concrete example from
https://github.com/sympy/sympy/issues/10800, consider this expression:
a = 2*Integral(sin(exp(x)), (x, 1, oo))+2*Si(E)
This

How could the future of the fast expression evaluation be suggested?
Would it be making the assumption system faster?
Or would it be choosing carefully between 'easy assumptions' and 'hard
assumptions' with time complexity analysis?
Or would it be not using assumption system at all, but may be

Hi Oscar,
Here's a few things that are different in SymEngine than SymPy.
> As an example it would be trivial in SymPy to make substitutions
involving large expressions and many replacements much faster with a
small redesign. The problem though is backwards compatibility: each
expression class
