A key element of the multicore software crisis is a
lack of abstraction: most parallel code mixes coordination and
computation, and assumptions about the architecture are often
hard-coded, tying the code to a specific architecture.
For problems with regular parallelism, portable parallel performance
may still be achieved by static compilation techniques that specialise
the code for the given architecture.
However, the more common case of irregular parallelism
can't be tackled statically;
instead dynamic specialisation and dynamic scheduling
AJITPar (Adaptive Just-In-Time Parallelisation) aims
to achieve portable parallel performance by combining dynamic
trace-based just-in-time compilation of a high-level parallel
functional language with dynamic demand-driven scheduling of
AJITPar is funded by EPSRC (EP/L000687/1), from October 2013 to May 2017.
