Can anyone help me to locate a literature reference for the concept of
a Cactus Stack? I have also heard it called a Saguaro Stack after a
particular species of cactus with a form such as:
! ! ! !__!
!__! ! !
Each ! represents the stack frame for an instance of a procedure,
and in practice could be of any height.
Each of the branches of the tree represents a separate stack of frames which
must coexist with those to its left and right.
When implementing a language such as occam which supports parallel
processes with stack frames of statically determinable sizes, these stack
frames may be mapped onto a linear address space by allocating space
for all parallel branches which need to coexist in sequential blocks
When the parallel processes have all terminated, all their stacks may be
I am writing a paper in which I need to refer to this concept and would
like to credit its inventor or an early user which I expect was over 20
years ago. Does anyone remember?
