[blind] why does not full supported with multithread?

HELLO

i’m using blind from deform mesh, but i found my cpu work only single multithread and not multithread?
this is normal or future feature supported full multithreads?

THEN i ask all you:
you can write here a list for full supported multithread:
-render blender
-cycles blender

  • other?

From what i remember sculpting with Multiresolution is multithreaded , but sculpting with Dyntopo i don’t think it is.
Some of the simulations are , not sure which ones though (the Ocean one is multithreaded) , and i remember people mentionning that the Blender Internal render is multithreaded, no idea about Cycles but it should be too.
