SMP scaling with surface tension problem

ck5285 · July 6, 2009, 05:39

Hi All
would like to know if anyone tried to run surface tension, laminar flow problem with more than 8 CPU cores with SMP? Any significant scaling beyond 8 cores?

Thanks

Hi no one ever do simulation involve surface tension with Flow-3D? any inputs?

not with 8+ cores with SMP. MPI - yes, it's been done.

Mike
so do we expect scaling improve with SMP in v9.4?

no, the smp performance in 9.4 has not been greatly improved. the plans are to invest in it for the following release to go to 8-16 cores and take advantage of the i7 architecture.
