I add the benchmark for Maple 15 in http://www.imcce.fr/trip/features.php
I take care to report the time used in the multiplication step for
SDMP and not the time used in the construction of the Maple DAG.
For example, I use the following code for the sparse example:
with(CodeTools):
sdmp:-info(1)

As far as I understand on my side, the problem with parallelization is
that malloc locks threads, therefore I can only parallelize code that
does not allocate memory. That's why I can not
I was surprised to still see a bit of this in practice on an 8x Core2 system
with the example from our paper:
f := (1 + x + y + 2*z^2 + 3*t^3 + 5*u^5)^12:
g := (1 + u + t + 2*z^2 + 3*y^3 + 5*x^5)^12:
What happens here is that we construct the result one term at a time, and
doing that requires a

My question was motivated by the fact that SDMP in Maple 14 seems to
be slower *in real time* with more than 4 cores for sparse
multiplication

Very similar. SDMP was refactored for Maple 15. It's size was cut in half,
it was made re-entrant to allow parallel polynomial algorithms, and we now
support Zp for multiprecision p. We added Kronecker s
I believe they are advertising on SDMP polynomial multiplication for
the parallel symbolic compution. TRIP has an interesting benchmarks
about that:

I'm curious to know if performance of Maple 15 are following the same
as for Maple 14.
