Hi Antonio,
[@list: sorry for the spam, I'm not sure if Antonio is subscribed and
mistakenly replied only to the list...]
I've investigated a bit and have produced two patches that make the FT
benchmark work.
patch 1 fixes some confusion when creating different cnodes and
increases the size of the page cnode by a factor of two. This fixes your
immediate problem of not being able to run the FT benchmark.
Additionally, changing the page cnode size should now be as easy as
modifying PAGE_CNODE_BITS in include/barrelfish_kpi/init.h.
patch 2 fixes the FT benchmark itself which was not working because the
default stack size on Barrelfish (64kB) is too small for the fft
implementation which creates rather large arrays on the stack. This
patch is not necessary if you're using a release older than
release2014-08-29.
Best,
-- Simon
