Forward inference techniques such as sequential Monte Carlo and particle
Markov chain Monte Carlo for probabilistic programming can be implemented in
any programming language by creative use of standardized operating system
functionality including processes, forking, mutexes, and shared memory.
Exploiting this we have defined, developed, and tested a probabilistic
programming language intermediate representation language we call probabilistic
C, which itself can be compiled to machine code by standard compilers and
linked to operating system libraries yielding an efficient, scalable, portable
probabilistic programming compilation target. This opens up a new hardware and
systems research path for optimizing probabilistic programming systems.Comment: In Proceedings of the 31st International Conference on Machine
