   > Cross posting to here. I think it worth to think about memory allocation strategy.
Specificially, we should design an API that contains a simple allocator(which is arena like
and allocate memory from a stack, and release everything once done), and use that allocator
for all memories in the program(including data structures and tensors). This will completely
eliminate the usage of system calls and allow the program o run in bare metal.
   
   
   @tqchen Removing all external allocator use and go with an embedded arena allocator sounds
a little bit fishy.  Bare-metal platforms does not necessarily lack a proper allocator; `newlib`,
for example, provides a pretty usable `dlmalloc` implementation.  Are there any other concerns?
