Hi,

I learned from this paper [1] that Yade's poromechanically coupled DEM+PFV scheme can be accelerated by 170x by combining four techniques: matrix factor reuse, multithreaded factorization, GPU accelerated factorization, and parallel task management.

I'm wondering that are these four technologies, especially the matrix factor reuse technique, currently being implemented in YADE? How can I apply these four techniques to the coupling problem in practice?

Thanks
Peilun
